This book investigates how fish experience their lives, their amazing senses and abilities, and how human actions impact their quality of life. The authors examine the concept of fish welfare and the scientific knowledge behind the inclusion of fish within the moral circle, and how this knowledge can change the way we treat fish in the future. In many countries fish are already protected by animal welfare legislation in the same way as mammals, but in practice there is still a major gap between how we ethically view these groups and how we actually treat them. The poor treatment of fish represents a massive animal welfare problem in aquaculture and fisheries, both in terms of the number of animals affected and the severity of the welfare issues. Thanks to its interdisciplinary scope, this thought-provoking book appeals to professionals, academics and students in the fields of animal welfare, cognition and physiology, as well as fisheries and aquaculture management.

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to mammals. Each chapter of this book has been written by specialists in their field. The subject matter is wide ranging and covers in detail concepts of animal welfare in addition to more specific aspects of fish welfare. Philosophical concepts of welfare are discussed along with more practical areas of fish welfare encompassing all husbandry and management activities that have a potential to affect the welfare of the fish in our care. This book is an essential purchase for fish veterinarians, fish farmers, fish biologists and those involved in the aquaculture industry and its regulation.

While there has been increasing interest in recent years in the welfare of farm animals, fish are frequently thought to be different. In many people's perception, fish, with their lack of facial expressions or recognisable communication, are not seen to count when it comes to welfare. Angling is a major sport, and fishing a big industry. Millions of fish are caught on barbed hooks, or left to die by suffocation on the decks of fishing boats. Here, biologist Victoria Braithwaite explores the question of fish pain and fish suffering, explaining what we now understand about fish behaviour, and examining the related ethical questions about how we should treat these animals. She asks why the question of pain in fish has not been raised earlier, indicating our prejudices and assumptions; and argues that the latest and growing scientific evidence would suggest that we should widen to fish the protection currently given to birds and mammals.

The welfare of fish in aquaculture is of increasing public concern in Europe and thus of growing importance for fish farmers. Although the topic can be regarded as controversial, due in particular to the lack of available knowledge, there is nevertheless an urgent need for fish farmers, authorities and scientists to develop criteria, approaches and practices to monitor and safeguard the welfare of cultured fish. The objective of this document is to provide the opinion of EIFAAC Member institutions– as the reference body in the field of inland fisheries and aquaculture – on how, given the current state of scientific knowledge, fish welfare issues can be integrated into best practice guidelines for fish culture. This report deals with the welfare of farmed finfish and neither addresses capture fisheries, be they commercial or recreational, nor welfare issues related to the culture of crustaceans and molluscs. The report focuses on the welfare issues of on-growing fish while giving little to no attention to larvae/fry and broodstock. Likewise, the report focuses primarily on the culture conditions for farming of fish and gives little attention to welfare aspects related to transport and slaughter. Finally, emphasis is given to the culture of freshwater fish, but marine species are included where appropriate. It is understood that the principal welfare issues are comparable for freshwater and marine fish culture.

Welfare is a multidimensional concept that can be described as the state of an animal as it copes with the environment. Captive environments can impact farmed animals at different levels, especially fishes, considering their highly complex sensory world. Understanding the ethology of a species is therefore essential to address fish welfare, and the interpretation of behavioral responses in specific rearing contexts (aquaculture or experimental contexts) demands knowledge of their underlying physiological, developmental, functional, and evolutionary mechanisms. In natural environments, the stress response has evolved to help animals survive challenging conditions. However, animals are adapted to deal with natural stressors, while anthropogenic stimuli may represent stressors that fishes are unable to cope with. Under such circumstances, stress responses may be maladaptive and cause severe damage to the animal. As welfare in captivity is affected in multiple dimensions, multiple possible indicators can be used to assess the welfare state of individuals. In the past, research on welfare has been largely focusing on health indicators and predominantly based on physiological stress. Ethological indicators, however, also integrate the mental perspective of the individual and have been gradually assuming an important role in welfare research: behavioral responses to stressors are an early response to adverse conditions, easily observable, and demonstrative of emotional states. Many behavioral indicators can be used as non-invasive measurements of welfare in practical contexts such as aquaculture and experimentation. Presently, research in fish welfare is growing in importance and interest because of the growing economic importance of fish farming, the comparative biology opportunities that experimental fishes provide, and the increasing public sensitivity to welfare issues.

Fish welfare is currently one of the most important concerns in aquaculture, and knowledge on how to improve fish welfare should be practical and implementable for all aquaculture farms. The objective of this Research Topic is to extend the current knowledge on fish welfare and to identify more comprehensive and practical indicators of the existing standard for fish welfare that are easily, more comprehensive and practical indicators in order to make it easy to implement on fish farms. A secondary objective is to identify which welfare issues are most relevant. It is important to mention that good fish welfare cannot simply be extrapolated from terrestrial animals. It has to take into consideration that different species of fish must also be taken into consideration. Whether these are species of commercial interest or not, they have different behaviour and respond differently to stress, and consequently, require a species-specific approach to improving their welfare. Intensive fish production systems have important negative consequences for the animals including impaired health and erratic behaviour. For many industries, their main goal is to achieve higher production whilst majority of the time, welfare is not take it into consideration. Better conditions for intensively produced farm animals, including fish, should result in improved efficiency and performance and higher quality product for consumers. We welcome papers demonstrating such effects. This research topic is related to the welfare of farmed fish. Fish welfare is related to how we treat our fish: the type of feed, how often we feed them, the stocking density that it is used, the environment where they are growing, how we grow them, from fertilized egg to fish ready to sell for public consumption. This Research Topic should address fish welfare during the whole growth period, and may also include papers on the attitudes and perceptions of stakeholders, including fish farmers and public about fish welfare.

Fishes are by far the most species-rich vertebrate taxon, and it is also the vertebrate group with the most strikingly diverse repertoire of behaviours and behavioural adaptations. As such, they provide us with many opportunities to explore the fascinating complexities of animal behaviour. Central questions addressed in this book include: How do se

Consumers, producers, stakeholders, governmental regulatory agencies and NGOs are becoming increasingly concerned with the conditions in which aquatic organisms are reared worldwide. High demand for fish for human consumption represents a challenge that has to be fulfilled by an ever-growing aquaculture production. In this scenario, animal care over the entire life and production cycle must be guaranteed while avoiding significant economic losses. As a result, research is needed to maximize yields and minimize adverse outcomes by optimizing rearing conditions while keeping in mind the welfare of cultured fish. In this Research Topic we will focus on relevant aspects related to fish response to both biotic and abiotic stressors as a means of improving their welfare, integrating both physiological and behavioral responses. In fish the adaptive responses to rearing may differ depending on several factors, including the characteristics of the stimuli and the intrinsic properties of the species or the selected line. If complete adaptation is missing, the application of single or multiple stimuli may result in a stress response. Stress responses have been linked to systemic adjustments which negatively impacts the immune system of fish, as well as their growth and reproductive performance. Therefore, one of the main interests of this Topic is to understand the allostatic responses of aquatic organisms to several stimuli/ factors that may be present during rearing. An additional focus of this Topic will be on conditions that may improve fish welfare by decreasing the stress response, such as implementing adequate swimming conditions. The focus of the Topic is to contribute to our present knowledge to better understand the physiological response of aquatic organisms, which is central to improving aquaculture practices. Emphasis will be placed on potentially existing interactions between physiological and endocrine pathways to build an overall stress response. Another aspect that will be considered in this Topic is how intraspecific variability may affect the stress response.
