The aim of this review is to assess the ethical implications of finfish aquaculture, regarding fish welfare and environmental aspects. The finfish aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal (...) welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists. However, most biologists are at present acknowledging the probability of fish being sentient creatures. Current aquaculture practices are affecting fish welfare during all four of the cited stages, both on physical and mental levels, as well as on the ability of fish to carry out natural behaviors. The effect fish farming has on the environment is here separated into five different categories: the decline of wild fish populations; waste and chemical discharge; loss of habitat; spreading of diseases; and invasion of exotic organisms. There is evidence of severe negative effects on the environment when looking at these five categories, even when considering the difficulty of studying environmental effects, due to the closely interacting variables. The ethical arguments and scientific evidences here reviewed have not all come to the same conclusions. Nevertheless, the general agreement is that current aquaculture practices are neither meeting the needs of fish nor environment. Thus, the obvious environmental and animal welfare aspects of finfish aquaculture make it hard to ethically defend a fish diet. (shrink)

EU regulations explicitly preclude recirculation aquaculture systems (RAS) for aquaculture grow-out from organic certification because they are not close enough to nature (Regulation (EEC) No. 710/2009). Meanwhile, according to another EU regulation, one criterion for organic food production is its contribution to sustainable development (Regulation (EEC) No. 834/2007). Against this background, one might argue that in spite of their distance to nature RAS are innovative solutions to sustainability issues in food production. The paper will deal with the claim (...) that RAS for aquaculture could be one innovative solution to sustainability issues. In this respect, the picture is ambivalent. In the past, the organic movement (OM) has searched for innovative alternatives to industrial forms of agriculture and food production that are non-sustainable. Hence, the majority of the OM does not feel fit to support industrial RAS, even though one might argue that these systems comply with many of the European OM’s founding principles. While there are potential positive effects for a sustainable development, we might still regard these systems as techno-scientific solutions to social problems. This paper discusses innovation narratives related to RAS from the perspective of post-normal innovation critique. It first presents potential contribution to a more sustainable food sector. It then contrasts these arguments within critical assessments of innovation narratives for sustainable development. Finally, the paper concludes by discussing moral challenges of RAS for the OM’s self-conception. (shrink)

From a certifier’s perspective, this paper deals with the question of how to bring together the values of producers and consumers in globalized food markets. It is argued that growth and mainstreaming of organic food production cannot be achieved solely by ethically aware consumers signalling their more sustainable purchase decision to the market. In fact, the intrinsic motivation of producers is an indispensable requisite for such a development. It is then the organic movement’s and the certifier’s task to bring together (...) the values of consumers and producers. This challenge is explored in the following by using the example of organic aquaculture. Based on one of the author’s experience in the field of aquaculture certification since the late 1990s, in about twenty countries and with most aquaculture animal species, the paper examines critical value-based aspects that are prominent from the perspective of sustainability. These are: use of problematic substances in aquaculture production, stocking density, origin of feedstuff, certification procedure, and small-scale farming versus large aquaculture companies. On this basis, the paper describes and analyses attempts to formulate respective organic certification standards. In order to bring about organic aquaculture, it is argued that consumers’ choices alone are not sufficient and that successful transformation to sustainable aquaculture also needs to take into account values and preferences of producers.

The principles of organic farming espouse a holistic approach to agriculture that promotes sustainable and harmonious relationships amongst the natural environment, plants, and animals, as well as regard for animals’ physiological and behavioral needs. However, open aquaculture systems—both organic and conventional—present unresolved and significant challenges to the welfare of farmed and wild fish, as well as other wildlife, and to environmental integrity, due to water quality issues, escapes, parasites, predator control, and feed-source sustainability. Without addressing these issues, it is (...) unlikely that open net-pen aquaculture production can be compatible with the principles inherent to organic farming. (shrink)

Aquaculture is the fastest growing animal producing sector in the world and is expected to play an important role in global food supply. Along with this growth, concerns have been raised about the environmental effects of escapees and pollution, fish welfare, and consumer health as well as the use of marine resources for producing fish feed. In this paper we present some of the major challenges salmon farming is facing today. We discuss issues of relevance to how to ensure (...) sustainability, by focusing on animal production systems, breeding approaches, sources for feed ingredients, and genetic engineering strategies. Other crucial issues such as animal welfare, environmental quality, and ethics are elaborated with regard to relevance for the sustainability of aquaculture. Additionally, we comment on socio-economic distributive implications by intellectual property rights (IPR) strategies on access to genetic material and traceability. To improve sustainability of salmon farming we suggest that there is a need for new approaches to guide research, for identification of ethical issues, and for engaging stakeholders in resolving these challenges.

The ethical issues raised by aquaculture were analyzed. A modification of the Ethical Matrix of the Food Ethics Council for the evaluation of novel foods was used; the Ethical Matrix was changed in order to include the various aquaculture production stages separately. The following stages were distinguished: the breeding stage, the growth/feeding stage, the “other-handling” stage (that includes disease and treatment, transportation of organisms, killing procedure, and DNA vaccinations), and the commercialization stage. The ethical issues concerning the producers, (...) the consumers, the environment, and the aquacultured organisms, are discussed. This scheme was fitted to the intensive cage-culture of carnivorous fish. The differences with other forms of aquaculture are discussed, and how the scheme extrapolates to them. The ethical evaluation of aquaculture, in practice, will be rather a utilitarian balancing of cost and benefits of the respective actions. The desired characteristics of an ethical evaluation have been also outlined. Ethical evaluation should not be limited to a purely scientific analysis; it should be holistic, comparable to available alternatives, and should have the flexibility to incorporate new data generated in the fast growing/continuous changing aquaculture sector.

In the 1950s, embryology in socialist China underwent a series of changes that adjusted the disciplinary apparatus to suit socialism and the national goal of self-reliance. As the Communist state called on scientists to learn from the Soviets, embryologists’ comprehensive view on heredity, which did not contradict Trofim Lysenko ’s doctrines, provided a space for them to advance their discipline. Leading scientists, often trained abroad in the tradition of experimental embryology, rode on the tides of Maoist ideology and repositioned their (...) research. Some of their creative realignment of previous research questions, materials, and traditions to Marxist philosophy and agricultural objectives generated productive programs. In particular, Tong Dizhou translated Engels’s dialectics of nature into a research question about cytoplasmic inheritance. His continuing investigation on it led to the first goldfish “clone” through a nuclear transplantation experiment; Zhu Xi and his associates transferred a goldfish model in embryology into studies on improving carp aquaculture, leading to a rare success in the Great Leap Forward of 1958. These directions for embryology continued well into the 1960s. At a time when global embryology was diversifying and began to be molecularized, eventually forming “developmental biology,” socialist embryology took shape in China with a different set of epistemic and practical commitments. The history of its development challenges and enriches our understanding of the concrete process of change in one discipline under Mao, showing ways in which scientists creatively adapted state-sanctioned ideologies and visions to do productive work outside the framework of molecular biology during the Cold War.

Industrial shrimp farming has been promoted by international development and financial institutions in coastal indebted poor countries as a way to obtain foreign exchange earnings, reimburse external debt, and promote development. The promotion of the shrimp industry is a clear example of a more general trend of support of export-oriented primary products, consisting in monocultures of commodities, as opposed to the promotion of more diverse, traditional production directed to feed the local population. In general, it is assumed that export-oriented (...) class='Hi'>aquaculture and agriculture, in a framework of liberalization policies, facilitates economic growth and this is associated with poverty reduction and the improvement of food security. However, it has been shown that the promotion of export-oriented production, mostly in the hands of big corporations, can have detrimental consequences for the livelihoods of local populations and the environment. As a result, international institutions, NGOs, and the industry aim to minimize these impacts by promoting sustainable export-oriented production. But some impacts may remain, since the main issue is the primary focus on international deregulated markets and the search for cheap primary products. To illustrate the relationships between the mainstream concept of development, the environmental and social impact of industrial farming systems, and the promotion of export-oriented production in developing countries, this article analyzes the case of the shrimp aquaculture industry.

New agricultural technologies are often justified morally in terms of their expected benefits, e.g., feeding the world's hungry. Such justifications stand or fall, not only on whether such benefits are indeed forthcoming, but on whether or not they are outweighed by attendant dangers. The practical details of easch case are, therefore, all-important. In this paper agriculture and aquaculture are examined from the perspective of ecosystem integrity, and with further reference to the uncertain effects of anthropogenic changes in the earth's (...) atmosphere. The principle of integrity provides a strong justification for a cautious approach to new technologies, and particularly so in the case of transgenics. (shrink)

Aquaculture is the fastest growing animal-production sector in the world. This leads to the question how we should guarantee fish welfare. Implementing welfare standards presupposes that we know how to weigh, define, and measure welfare. While at first glance these seem empirical questions, they cannot be answered without ethical reflection. Normative assumptions are made when weighing, defining, and measuring welfare. Moreover, the focus on welfare presupposes that welfare is a morally important concept. This in turn presupposes that we can (...) define the capacities of fish, which is an empirical undertaking that informs and is informed by ethical theories about the moral status of animals. In this article we want to illustrate the need for a constant interaction between empirical scientific research and ethics, in which both fields of research make their own contribution. This is not a novel claim. However, the case of fish sheds new light on this claim, because regarding fish there is still much empirical uncertainty and there is a plurality of moral views on all levels. Therefore, we do not only want to show the necessity of this interaction, but also the added value of a cooperation between ethicists and empirical scientists, such as biologists, physiologists, and ethologists. We demonstrate this by considering the different steps in the process of reflection about and implementation of fish welfare. (shrink)

Improvements in production methods over the last two decades have resulted in aquaculture becoming a significant contributor to food production in many countries. Increased efficiency and production levels are off-setting unsustainable capture fishing practices and contributing to food security, particularly in a number of developing countries. The challenge for the rapidly growing aquaculture industry is to develop and apply technologies that ensure sustainable production methods that will reduce environmental damage, increase productivity across the sector, and respect the diverse (...) social and cultural dimensions of fish farming that are observed globally. The aquaculture industry currently faces a number of technology trajectories, which include the option to commercially produce genetically modified (GM) fish. The use of genetic modification in aquaculture has the potential to contribute to increased food security and is claimed to be the next logical step for the industry. However, the potential use of these technologies raises a number of important ethical questions. Using an ethical framework, the Ethical Matrix, this paper explores a number of the ethical issues potentially raised by the use of GM technologies in aquaculture. Several key issues have been identified. These include aspects of distributive justice for producers; use of a precautionary approach in the management of environmental risk and food safety; and impacts on the welfare and intrinsic value of the fish. There is a need to conduct a comparative analysis of the full economic cycle of the use of GM fish in aquaculture production for developing countries. There is also a need to initiate an informed dialogue between stakeholders and strenuous efforts should be made to ensure the participation of producers and their representatives from developing nations. An additional concern is that any national licensing of the first generation of GM fish, i.e., in the USA, may initiate and frame an assessment cycle, mediated by the WTO, which could dominate the conditions under which the technology will be applied and regulated globally. Therefore, an integrated analysis of the technology development trajectories, in terms of international policy, IPR, and operational implications, as well as an analysis of a broader range of ethical concerns, is needed.

Social license reflects environmental and social change, and sees community as an important stakeholder and partner. Science, scientists, and science policy have a key role in the processes that generate social license. In this paper, we focus on the interaction between science and social license in salmon aquaculture in south-eastern Tasmania. This research suggests that social license will be supported by distributed and credible knowledge co-production. Drawing on qualitative, interpretive social research we argue that targeted science, instilled by appropriate (...) science policy, can underpin social license by supporting emerging, distributed, and pluralistic knowledge production. Where social license is important and environmental contexts are complex, such knowledge production might support environmental governance, and so improve outcomes in coastal zone management and beyond.

Aquaculture plays a significant role in both economic development and food production. Maintaining an ecological environment with good water quality is essential to ensure the production efficiency and quality of aquaculture. Effective management of water quality can prevent abnormal conditions and contribute significantly to food security. Detecting anomalies in the aquaculture environment is crucial to ensure that the environment is maintained correctly to meet healthy and proper requirements for fish farming. This article focuses on the use of (...) deep learning techniques to detect anomalies in water quality data in the aquaculture environment. Four deep learning anomaly detection techniques, including Autoencoder, Variational Autoencoder, Long-Short Term Memory Autoencoder, and Spectral-Residual Convolutional Neural Network, were analysed using multiple real-world sensor datasets collected from IoT aquaculture systems. Extensive experiments were conducted for temperature, dissolved oxygen, and pH parameters, and the evaluation analysis revealed that the Long-Short Term Memory Autoencoder anomaly detection method showed promising results in detecting anomalies for the temperature and oxygen datasets, while the Spectral-Residual Convolutional Neural Network demonstrated the best performance on the pH datasets.

Climate cuisine is about eating the future you want into being. In this article, I examine how seaweed recipes can be forms of climate fiction through the way that the reader is invited to participate in sustainable foodways. I examine several popularizations of seaweed aquaculture that imagine practices of eating and growing seaweeds. Their formal similarities center on participation: they include the direct address of the reader through the second person voice, and position themselves as instructional models. Bren Smith’s (...) Eat Like a Fish (Smith, Eat like a fish: My adventures as a fisherman turned restorative ocean farmer, Penguin, 2019) interpellates the reader as eater, invited to cultivate eating habits that, on a societal scale, would produce a more materially sustainable relation with the planet. The vignette “Ghost Bar,” which appears in Holly Jean Buck’s After Geoengineering: Climate Tragedy, Repair, and Restoration (Buck, After geoengineering: Climate tragedy, repair, and restoration, Verso, 2019), sensorily emplaces the reader in a future seaweed farm as a window into the kinds of livelihoods and forms of work that could be part of mitigating global warming. I trace the similarities between Smith's recipes and Buck’s interpellation of a reader, both of which use the second-person mode addressing an unmarked “you,” inviting this “you” to imagine and actualize the future dish or future scenario they sketch. While these texts have their own limitations at the level of the social imagination, such popularizations of seaweed aquaculture model an important way of understanding the intimacies of climate fiction and recipes. Recipes not only popularize the sustainable eating of seaweeds, but actively constitute a form of climate fiction through their intention to actualize more seaweedy futures. (shrink)

The global seafood industry is a vital source of food, income, livelihoods, and culture. Seafood demand is steadily rising due to growth in the global human population, affluence, and per capita consumption. Seafood supply is also growing, despite declining wild fish stocks, with phenomenal advances in aquaculture, that is, the cultivation of aquatic organisms. Aquaculture supplied 42 % of the world’s fish in 2012 and is forecast to eclipse capture fisheries production by 2030. The balance between these two (...) seafood production systems has profound implications for global food security, income distribution, and ecological sustainability. Here, a qualitative analysis of the ethics and sustainability of capture fisheries and aquaculture is presented. An innovative practical ethics approach is introduced which adapts the ethical matrix, a conceptual tool for analyzing the wellbeing, autonomy, and justice of different interest groups, and Rapfish, a rapid appraisal technique used to evaluate the sustainability of fisheries along six performance modalities, including ethics. Using case studies of global large- and small-scale capture fisheries and generalized carnivorous and omnivorous aquaculture systems, I show that human institutions and social actors interact in complex governance processes to influence seafood ethics and sustainability.

This study brings an organizational identity perspective to the debate regarding corporate social responsibility (CSR) and multinational corporations (MNCs). The basic proposition is that organizational identities warrant closer attention since they influence CSR strategies. It is further argued that a more explicit distinction between principles and practices, or between 'being' and 'doing', is needed when debating whether multiple organizational identities are required for MNCs operating in locations characterized by different stakeholder demands. In terms of identity construction, two translation processes are (...) suggested to be pertinent; from hypernorms to organizational principles and the translation of organizational principles to practices. The first translation is relevant since 'hypernorms' alone do not create the distinctiveness needed for an organizational identity to develop and the second translation helps in explaining the ability to endorse local contracts.

The Tasmanian salmon industry has become one of the state's most profitable industries to date. Though production conditions notoriously lack transparency, there is a clear dependency on the mass production of complex nonhuman animals who are kept in inappropriate conditions and subject to harmful industry practices. This article explores why the Tasmanian Environmental Protection Agency recently approved the construction of the largest salmon hatchery in Australia, despite serious environmental sustainability and welfare concerns. It considers the likely impact of the new (...) hatchery on the welfare of both the farmed nonhuman animals and the surrounding free-ranging life and advocates for industry improvements that are guided by considerations of nonhuman animal welfare and environmental sustainability.

This paper reviews development research and policies on freshwater fish in South and Southeast Asia. We conduct a systematic review of academic literature from three major science-based policy institutions to analyze development research and policies that have accompanied the ongoing transition from freshwater capture fisheries to aquaculture in the region. Using a ‘food fish system’ framework allows for the identification and systematic comparison of assumptions underpinning dominant development policies. We analyze the interrelations between the production, provisioning, and consumption of (...) wild and farmed fish and demonstrate a shift toward food fish systems thinking in the sampled literature. We discuss gaps and weaknesses in the literature, as identified through the application of the food fish systems framework and present an agenda for future research aimed at securing the potential of fish as food.

Sustainable development poses highly complex issues for those who attempt to implement it. Using the Brundtland Commission’s definition of sustainable development as a vantage point, this article discusses the issues posed by the production of one kind of food, farmed Atlantic salmon, as a means of illustrating the complexity, interconnectedness and high-data requirements involved in assessing whether a given industry is sustainable. These issues are explored using the three commonly accepted aspects of sustainability – its environmental, social and economic aspects (...) – and the dilemmas posed by the need to make the trade-offs necessary among these. It concludes by arguing that decisions of this complexity require complex and multiple decision-making structures and suggests four that are essential for the task. (shrink)

The future of salmon aquaculture depends on the adoption of alternative feed resources in order to reduce the need for fish meal and fish oil. This may include resources such as species from lower trophic levels, by-products and by-catch from fisheries and aquaculture, animal by-products, plants, genetically modified (GM) plants, nutritionally enhanced GM plants and products from microorganisms and GM microorganisms. Here, we report on a deliberative assessment of these alternative feed resources, involving 18 participants from different interest (...) groups within Norwegian salmon aquaculture. The participants defined a broad range of appraisal criteria concerning health and welfare issues, economical issues, environmental issues, and knowledge and social issues. A number of uncertainties, in the form of incomplete knowledge, diverging opinions, and context specific factors were identified when the participants evaluated the alternatives. Our findings support the need for more research on the suitability of alternative feed resources for farmed salmon. Additionally, the study underlines the importance of facilitating deliberative assessments in order to map the plurality of perspectives and explore qualitative aspects of uncertainty. Such initiatives improve the information base upon which decisions on future feed resources for farmed salmon are made. (shrink)

The development of the aquaculture industry in Canada has triggered a conflict of a scope never seen before. As stated in Young and Matthews’ The Aquaculture Controversy, this debate has “mushroomed over the past several decades to become one of the most bitter and stubborn face-offs over industrial development ever witnessed in Canada” (Young and Matthews in The aquaculture controversy in Canada. Activism, policy and contested science. UBC Press, Vancouver, p 3, 2010). It opposes a wide variety (...) of actors: from industrial investors, scientists, politicians and environmentalists to Native associations and communities, citizens groups and local stakeholders. The opposition is fierce between those in favor of a flourishing and modern aquaculture of industrial nature and those who fear the dreadful consequences of such an industry. In particular, the possible implementation of biotechnology innovations, such as a genetically modified salmon, has made this debate coextensive with the GMO debate, thus multiplying the opposition’s spectrum of arguments against the industry. Throughout the debate, Canadian environmental NGOs like the Suzuki Foundation and Greenpeace Canada have assumed leadership over the opposition to aquaculture development with certain success. Their participation in the debate features numerous ethical concerns related to environmental health, a respect for wilderness and local human communities. Such a position can be associated overall with a form of ecocentric ethics or concern. Nevertheless, a careful examination of the technical solutions proposed by these NGOs reveals their embeddedness in biocentrism. Through the example taken from the Canadian debate on aquaculture development, this paper aims to highlight the conceptual difficulty of enacting ecocentric ethical positions beyond formal arguments. Because ecocentrism implies a true paradigm shift, not only in mentality, but also in the way we conceive our technical interventions in nature, biocentrism remains an important practical method to enact ethical positions related to environmental concerns in public debates.

The status of wild capture fisheries has induced many fisheries and conservation scientists to express concerns about the concept of using forage fish after reduction to fishmeal and fish oil, as feed for farmed animals, particularly in aquaculture. However, a very large quantity of forage fish is being also used untransformed (fresh or frozen) globally for other purposes, such as the pet food industry. So far, no attempts have been made to estimate this quantum, and have been omitted in (...) previous fishmeal and fish oil exploitation surveys. On the basis of recently released data on the Australian importation of fresh or frozen fish for the canned cat food industry, here we show that the estimated amount of raw fishery products directly utilized by the cat food industry equates to 2.48 million metric tonnes per year. This estimate, plus the previously reported global fishmeal consumption for the production of dry pet food suggest that 13.5% of the total 39.0 million tonnes of wild caught forage fish is used for purposes other than human food production. This study attempts to bring forth information on the direct use of fresh or frozen forage fish in the pet food sector that appears to have received little attention to this date and that needs to be considered in the global debate on the ethical nature of current practices on the use of forage fish, a limited biological resource.

As the world population is growing and government directives tell us to consume more fatty acids, the demand for fish is increasing. Due to declines in wild fish populations, we have come to rely more and more on aquaculture. Despite rapid expansion of aquaculture, this sector is still in a relatively early developmental stage. This means that this sector can still be steered in a favorable direction, which requires discussion about sustainability. If we want to avoid similar problems (...) to the ones we have experienced with livestock farming, we need to generate knowledge of the biology, profitability, environmental aspects, consumer awareness, and product appreciation of particular fish species. However, the discussion about a sustainable aquaculture also raises the question how we should treat fish. This moral question is regularly addressed as a problem of applied ethics with a focus on tailoring ethical principles to practical questions. In this article we do not deny the importance of the practical accounts, but we start from the fundamental question whether and why fish matter in our moral deliberations, i.e., from the discussion on moral status. We elaborate the distinction between moral considerability and moral significance in order to show both the importance and the limitations of the discussion about moral status for practical problems in aquaculture. We illustrate these points with a case-study about the farming of a specific fish species, the African catfish. (shrink)

Nanoparticles have multifaceted advantages in drug administration as vaccine delivery and hence hold promises for improving protection of farmed fish against diseases caused by pathogens. However, there are concerns that the benefits associated with distribution of nanoparticles may also be accompanied with risks to the environment and health. The complexity of the natural and social systems involved implies that the information acquired in quantified risk assessments may be inadequate for evidence-based decisions. One controversial strategy for dealing with this kind of (...) uncertainty is the precautionary principle. A few years ago, an UNESCO expert group suggested a new approach for implementation of the principle. Here we compare the UNESCO principle with earlier versions and explore the advantages and disadvantages by employing the UNESCO version to the use of PLGA nanoparticles for delivery of vaccines in aquaculture. Finally, we discuss whether a combined scientific and ethical analysis that involves the concept of responsibility will enable approaches that can provide a supplement to the precautionary principle as basis for decision-making in areas of scientific uncertainty, such as the application of nanoparticles in the vaccination of farmed fish.

In the last decades aquaculture is receiving great attention because of its health-related benefits.The objective of this work was to verify the socioeconomic profile and identify the fish consumption of individuals residing in the municipality of Seara, located in the west of Santa Catarina state, as well as the quantity they consume and the reasons that would make them consume more fish. The research has a quali-quantitative, descriptive, and transversal nature. 376 individuals were interviewed, with a questionnaire consisting of (...) 30 objective and subjective questions. This research project was submitted to and approved by the Ethics and Research Committee of the Universidade Federal da Fronteira Sul (UFFS). The results showed that as the level of education and income increases, so does the amount of fish consumed by the interviewees. It was noticed that a large part of the population consumes fish, however the amount consumed is below the recommended. Among the reasons that would make the population increase their fish intake are more accessible prices and incentives. (shrink)

This book explores food from a philosophical perspective, bringing together sixteen leading philosophers to consider the most basic questions about food: What is it exactly? What should we eat? How do we know it is safe? How should food be distributed? What is good food? David M.

However, until recently, few have considered food a standard subject for (...) serious philosophical debate. Each of the essays in this book brings in-depth analysis to many contemporary debates in food studies—Slow Food, sustainability, food safety, and politics—and addresses such issues as “happy meat,” aquaculture, veganism, and table manners. The result is an extraordinary resource that guides readers to think more clearly and responsibly about what we consume and how we provide for ourselves, and illuminates the reasons why we act as we do.

Our paper contributes to Science, Technology and Society scholarship on the practices and technologies of containment. We build on existing work in STS that has analyzed containment as a performative sociotechnical system that generates and sustains new realities, new systems, and new relationships. Our contribution draws from the problem of containment in salmon aquaculture. The stakes for containing salmon are very high. Farmed salmon escapes are environmentally damaging to ecosystems and wild salmon populations, and they put additional pressure on (...) an industry that has a very poor environmental record. We consider in detail Newfoundland and Labrador’s “Code of Containment” that works to keep farmed salmon in cages and prevent them from escaping into the wild. Through our analysis of the Code, we argue that containment is not only about holding inside. It is also about holding together, an obsolete meaning of the term “to contain.” We add to STS scholarship by arguing that containment and its associated Code in Newfoundland holds together a large scale, industrial aquaculture sector that tolerates persistent farmed salmon escapes into the wild from ocean-based cages. We conclude by examining the broader implications of our analysis for STS scholarship on the practices and technologies of containment. (shrink)

Future global food insecurity due to growing population as well as changing consumption demands and population growth is sometimes suggested to be met by increase in aquaculture production. This raises a range of ethical issues, seldom discussed together: fish welfare, food security, human health, climate change and environment, and public concern and legislation, which could preferably be seen as pieces in a puzzle, accepting their interdependency. A balanced decision in favour of or against aquaculture needs to take at (...) least these issues into consideration. It is further argued that in the parallel discussion on increased livestock production animal welfare is an inevitable element both in relation to current legislation in many countries but also in relation to our perception of moral, whereas awareness of fish welfare is low. Both EU legislation and labelling concerning fish is mainly limited to environmental aspects. It is argued that EU shows a split perception of fish, on the one hand acknowledging scientific evidence of fish capacities but on the other excludes fish from detailed legislation. Combining the claim of the Treaty of Lisbon to pay full regard to animal welfare and scientific evidence fish are sentient it is concluded that fish welfare need to be considered in any farming practice and any ethical consideration of increased aquaculture. This might be facilitated taking a basis in our own vulnerability and interdependence, combined with moral responsibility to show sentient beings a ‘loving kindness’—an extension of Cora Diamond’s argument regarding mammals.

In Scotland, residents have fought open-net salmon farms and their toll on human and nonhuman bodies for decades. This paper recollects seven years of work in Skye and Raasay, two islands off the northwest coast of the country, developing strategies to divest away from salmon aquaculture. Addressing the contemporary wave of underwater clearances created by UK’s top food export industry, it unpacks the implementation of a transition into alternative horizons by embracing the legacies of toxicity inherited from salmon extractivist (...) industries. CLIMAVORE, a framework developed as a research-led artistic practice by the authors, investigates how to eat in the new seasons of the climate crisis. In a season of marine dead zones, it facilitates new approaches to aquaecology and coastal care that cultivate coastal livelihoods. CLIMAVORE began with a new public forum, shaped as a multispecies intertidal table, established in Skye in 2017 to envision environmentally regenerative and socially reparative forms of food production based on metabolic interactions between humans and depleted landscapes that benefit a plethora of species. CLIMAVORE’s site responsive methodology relies on a socially-engaged art practice, consisting of fieldwork, interviews, working groups, oral histories, performative meals, cooking and building apprenticeships, tidal gardening, material testing and public art installations. Ongoing collaboration with residents, scientists, and policymakers critically explores ways of living not only on but with the coast. This new holistic approach to coastal nourishment provides methodologies for ecological praxis as well as a platform for researchers and the general public to imagine an alternative ecological future: the tidal commons.

Advanced biopreservation technologies using subzero approaches such as supercooling, partial freezing, and vitrification with reanimating techniques including nanoparticle infusion and laser rewarming are rapidly emerging as technologies with potential to radically disrupt biomedicine, research, aquaculture, and conservation.

With the potential to process the world's agricultural and food waste, provide sustainable fodder for livestock, aquaculture, and pet animals, as well as act as a source of novel biomolecules, the black soldier fly, Hermetia illucens, has been launched into the leading position within the insects as feed industry. Fulfilment of these goals, however, requires mass‐rearing facilities to have a steady supply of neonate larvae, which in‐turn requires an efficient mating process to yield fertile eggs; yet, little is known (...) about adult reproductive behavior, nor what physiological factors lead to its emergence. Moreover, fertile egg production tends to be highly variable in colony. Therefore, this review brings together what is currently known of the organismal biology of H. illucens, compiling information on adult morphology, physiology, biogeography, genomics, and behavioral ecology. As a holistic synthesis, it highlights several directions of interest for research to follow. (shrink)

This article presents and evaluates arguments supporting that an approval procedure for genome-edited organisms for food or feed should include a broad assessment of societal, ethical and environmental concerns; so-called non-safety assessment. The core of analysis is the requirement of the Norwegian Gene Technology Act that the sustainability, ethical and societal impacts of a genetically modified organism should be assessed prior to regulatory approval of the novel products. The article gives an overview how this requirement has been implemented in the (...) regulatory practice, demonstrating that such assessment is feasible and justified. Even in situations where genome-edited organisms are considered comparable to non-modified organisms in terms of risk, the technology may have—in addition to social benefits—negative impacts that warrant assessments of the kind required in the Act. The main reason is the disruptive character of the genome editing technologies due to their potential for novel, ground-breaking solutions in agriculture and aquaculture combined with the economic framework shaped by the patent system. Food is fundamental for a good life, biologically and culturally, which warrants stricter assessment procedures than what is required for other industries, at least in countries like Norway with a strong tradition for national control over agricultural markets and breeding programs.

Este trabajo surge a partir de la investigación general de las técnicas hidropónicas teniendo en cuenta sus ventajas y desventajas para de esta forma poder encontrar aquel factor determinante a través de una comparación de técnicas hidropónicas que permitan clasificarlas y escoger la mejor opción que genere menos impacto ambiental negativo y demuestre ser más productivo en los entornos urbanos. Adicionalmente, un factor determinante en las ciudades es su espacio limitado por lo que la mejor opción también deberá incluir un (...) óptimo manejo del espacio que permita a casi cualquier individuo poder aplicarlos desde su entorno sin recurrir a excesivas modificaciones. Como principal resultado se escogió a la Hidroponía recirculante como método predominante por los excelentes resultados que se obtienen con relación a los demás, adicionalmente, este puede ser fácilmente aplicado en los ambientes urbanos por su versatilidad y buen manejo de recursos.

When, if ever, is it better to spend money to improve pig welfare over chicken welfare? Which species of fish is worst off in commercial aquaculture operations? When, if ever, would humans benefit less from a policy than animals stand to lose? The answers to these questions involve making interspecies welfare comparisons—assessments of how well or poorly the members of one species are faring compared to the members of another species. It’s important to answer these questions, as governments, NGOs, (...) and private actors regularly make decisions that assume particular views about them. However, there is no accepted method for making interspecies welfare comparisons; welfare assessment tools are designed to make comparisons within species, not across them. This volume addresses this crucial gap in the literature: it proposes a methodology for making such comparisons, it puts that methodology into practice, and then reports some tentative, proof-of-concept results. This book reports the results of a collaborative, 20-month, interdisciplinary project on making interspecies welfare comparisons. It includes contributions from philosophers, neuroscientists, comparative psychologists, animal welfare scientists, and many others. Unlike many edited volumes, this book is the product of a joint enterprise with a specific, shared goal: to develop a way to make principled comparisons between courses of action that affect different kinds of animals. This book reflects the contributors’ collective view about one way to achieve that goal. (shrink)

This article discusses the extent to which Global Value Chain governance may lead to animal welfare improvement and help to alleviate animal suffering in food producing chains. Our approach relied on scrutinizing two of the most used compulsory certification templates which are enforced by major buyers to their suppliers in order to assure responsible activity in the farmed fish chain and in the wild-captured fish chain. Since fish may experience intense suffering in regular activities involved in catching, maintenance, transport and (...) management, we analyzed whether those instruments can contribute to improve the welfare of fish. Although positive outcomes may be expected in aquaculture production, serious welfare issues regarding wild-capture fish are brought to the fore and preliminary action is proposed. We present recommendations for improving the positive impacts of such certification schemes in GVCs and argue that sustainability-driven standards could also embrace more AW-focused criteria in order to contribute with reducing unnecessary animal suffering in the fish chain.

IntroductionNowadays, biotechnology has a significant influence on different aspects of human life. The applications of biotechnology are so broad, and the advantages so compelling, that virtually every industry is using this technology. Developments are under way in areas as diverse as pharmaceuticals, diagnostics, textiles, aquaculture, forestry, chemicals, household products, environmental cleanup, food processing, and forensics, to name a few. Biotechnology is enabling these industries to make new or better products, often with greater speed, efficiency, and flexibility. Biotechnology is any (...) technological application that uses biological systems, living organisms, or derivatives thereof to make or modify products or processes for specific use. It applies the knowledge of biology to enhance and improve the environment, health, and food supply. Using biotechnology, scientists work to develop environment-friendly alternatives to fossil fuels and plastics; new medicines, vaccines, and. (shrink)

If we are to better understand and negotiate current and future problems in the food supply chain, it will be essential to pay more attention to the role and position of professionals involved. 'Professionals in food chains' addresses questions as: What are the main ethical challenges for professionals in the food supply chain? Who within this complex field holds responsibility for what? What does it mean for the food-related professions to operate in an atmosphere of immense social tension and high (...) expectations? Which virtues are required to do a 'good' job? In brief: What can be said about the roles, responsibilities, and ethics of professionals across this dynamic field? Topics covered include general issues on professional roles and responsibility, sustainable food supply chains, novel approaches in food production systems, current food politics, the ethics of consumption, veterinary ethics, pedagogical/educational and research ethics, as well as aquacultural, agricultural, animal, and food ethics.

This paper explores citizens’ views about the welfare of farmed fish and the mental abilities of fish with a large survey data sample from Finland (n = 1,890). Although studies on attitudes towards animal welfare have been increasing, fish welfare has received only limited empirical attention, despite the rapid expansion of aquaculture sector. The results show that the welfare of farmed fish is not any great concern in the Finnish society. The analysis confirms the distinct character given to farmed (...) fish compared to traditional farmed animals. Salmon are rated low in their mental abilities, including the capacity to feel pain, which may weaken ethical concerns for fish welfare. When analyzing the social determinants surrounding the rating of the welfare of farmed fish, it was shown that fish welfare attitudes follow general animal welfare attitudes regarding age and place of residence as fish welfare tends to be rated more negatively among younger age groups and among urban residents. However, no clear connection could be identified between gender and the rating of fish welfare, which may suggest that the distinct cultural categorization of fish diminishes the typical gender difference identified in animal attitudes. It is concluded that in order to improve awareness about fish welfare, there is a need to increase dissemination of scientific knowledge about fish and their welfare. Moreover, further research should be directed toward studying the moral positioning of fish and the distinct moral categorization they receive. (shrink)

Labelling schemes are practical arrangements aimed at making 'ethical' products widely available and visible. They are crucial to expanded development of ethical markets and hence to the addition of moral dimensions to the normally amoral behaviour linking consumers and retail and production businesses. The study reported here attempts to assess the contribution of UK ethical, social and environmental certification and labelling initiatives to 'sustainable' consumption and production. The research sought to assess the overall potential of initiatives to inject human values (...) into the supply-distribution chains, through a qualitative survey of 15 of the 26 main UK initiatives: in social justice, animal welfare and environmental sustainability from the agriculture, food processing, timber, aquaculture, textiles and personal care sectors. By analysing the basic characteristics and concepts of these labels and investigating the emergence of labelling initiatives, we assess whether labels help add an ethical dimension, or whether, in some respects, they also reduce such missions to the technical management of adding only another 'utility' to a product. The analysis assesses whether the gradual 'mainstreaming' of ethical initiatives such as 'Fairtrade' risks subsuming ethical goals within business participants' competitive and profit-oriented logics. However, the contrasting perspectives revealed between rival labelling initiatives show that the scope and functions of labelling projects go beyond the manifest ones of information communication between consumers and producer and actually introduce elements of socio-political regulation. These are essential for more sustainable and ethical business practices and are an integral part of any humanisation of business involvement. (shrink)

Concerns have been voiced about the ethical implications of patenting practices in the field of biotechnology. Some of these have also been incorporated into regulation, such as the European Commission Directive 98/44 on the legal protection of biotechnological inventions. However, the incorporation of ethically based restrictions into patent legislation has not had the effect of satisfying all concerns. In this article, we will systematically compare the richness of ethical concerns surrounding biotech patenting, with the limited scope of ethical concerns actually (...) addressed in the patent system. As sources of our analyses we will use literature and document studies and a survey with important stakeholders and experts related to Norwegian patenting in the aquacultural biotechnology sector. We will structure the analyses with an ethical matrix, developed for this purpose. Showing the misalignment of the discussions within and outside the patent system, we suggest that an important reason for the ethical controversy still surrounding patenting is that ethical questions keep being framed in a narrow way within the system. Until a richer set of ethical considerations is addressed head-on within the patent system, the patent system will continue to evoke academic and interest group criticism, potentially contributing to a legitimacy crisis of the whole system.

There is an increasing body of literature proposing to include animal welfare in the United Nations Sustainable Development Agenda. The main argument is the potential positive effect that improving the welfare of animals could have over the health and welfare of humans. However, recent literature suggests that the welfare interests of animals should also be considered. Based on these premises, an analysis of the practical implications of including animal welfare in the United Nations Sustainable Development Goals is granted. The aim (...) of this study is to address this by applying the case of animals in the agriculture and aquaculture systems. Animal farming inherently affects the welfare of a substantial number of sentient animals while, the welfare of farmed animals has been connected to human wellbeing and several environmental issues. The study highlights the feasibility of incorporating the welfare of farmed animals into a future version of the SDGs. It does so by developing a model based on a set of human-focused (anthropocentric) and animal-focused (sentientistic) targets for each of the 17 goals. It has been argued that expanding the scope of the SDGs from anthropocentrism to sentientism creates a synergy between human and animal welfare and, on top of that, is progress towards sustainability.

The welfare of farmed fish is often regarded with less concern than the welfare of other husbandry animals, as fish are not universally classified as sentient beings. In Norway, farmed fish and other husbandry animals are legally protected under the same laws. Additionally, the legislature has defined a number of aquaculture-specific amendments, including mandatory welfare courses for fish farmers who have a key role in securing animal welfare, also with regards to noting welfare challenges in the production process. This (...) article uses fish welfare courses as a site from which to inquire about the common-sense understanding of fish welfare in Norwegian fish farming. The focus is specifically on fish farm employees, their experiences of welfare-related issues and contradictions in their daily work, and the struggle to act responsibly in aquaculture settings. Through participant observation at welfare courses, as well as interviews and conversations with fish farm workers, the article details how challenges are experienced ‘on the ground’, and suggests how fish farm workers’ own experiential knowledge might be mobilized to improve the general welfare of farmed fish.

To better detect fish in an aquaculture environment, a high-accuracy real-time detection model is proposed. An experimental dataset was collected for fish detection in laboratory aquaculture environments using remotely operated vehicles. To overcome the inaccuracy of the You Only Look Once v3 algorithm in underwater farming environment, a suitable set of hyperparameters was obtained through multiple sets of experiments. Then, a real-time image recovery algorithm is applied before YOLOv3 to reduce the effects of both noise and light on (...) images whilst keeping the real-time capability, leading to a mean average precision of 0.85 and frame rate of 17.6 fps, respectively. Finally, compared with the base detection model using only the YOLOv3 algorithm, the enhanced detection model presented results in a reduction of miss detection rate from 23% to only 9% across different environments and with the detection accuracy of the target in different environments being improved from 8% to 37%.
