Yet, a growing body of evidence related to cognitive (Braithwaite 2006), neuroanatomic (Portavella and Vargas 2005;Rodriguez et al 2006) and emotional (Sneddon 2007;Yue et al 2008) aspects of fish behaviour provides strong support for sentience (the ability to feel) in fish.…”

Behaviour represents a reaction to the environment as fish perceive it and is therefore a key element of fish welfare. This review summarises the main findings on how behavioural changes have been used to assess welfare in farmed fish, using both functional and feeling-based approaches. Changes in foraging behaviour, ventilatory activity, aggression, individual and group swimming behaviour, stereotypic and abnormal behaviour have been linked with acute and chronic stressors in aquaculture and can therefore be regarded as likely indicators of poor welfare. On the contrary, measurements of exploratory behaviour, feed anticipatory activity and rewardrelated operant behaviour are beginning to be considered as indicators of positive emotions and welfare in

“…In fish, the regulation of stress involving psychological components is not well studied and there is even a current debate about whether fish possess sufficient psychological capacities for mental assessment of stressful situations (e.g. Rose 2002Rose , 2007. However, there is a body of indirect indicators supporting the possibility that fish may develop similar mental processes.…”

“…This is however a matter of controversy since, to some authors, the lack of neocortex is a number one reason to deny any form of consciousness to fish (Rose, 2002(Rose, , 2007Iwama, 2007). Furthermore, only very simple forms of learning (habituation, simple classical conditioning) were traditionally attributed to fish, all regulated at the brainstem level (Rodriguez et al, 2006).…”

Galhardo L, Oliveira RF. Psychological Stress and Welfare in Fish. Annu Rev Biomed Sci 2009;11:1-20. The ability to respond to stress is vital to the survival of any living organism, though sustained reactions can become detrimental to the health and welfare of animals. Stress responses of vertebrates are known through several studies in their physiological, behavioural and psychological components, under acute and chronic contexts. In fish, the physiological and behavioural aspects of stress are considerably well known phenomena and show striking similarities to those of other vertebrates. However, the psychological component is not well known. Some authors deny mental experiences to fish on the basis of their lack of neocortex. Nevertheless, recent studies have shown neuroendocrine, cognitive and emotional processes in fish that are not only equivalent to other vertebrates, but also allow inferring some forms of mental representation. The integration of psychological elements in fish stress physiology is insufficiently studied, but, as discussed in this article, there is already indirect evidence to admit that some form of stimuli appraisal can take place in fish. This fact has profound implications on the regulation of the stress response, as well as on fish welfare and its management.

“…For example, Rose (2002Rose ( , 2007 considers that fish are incapable of experiencing the emotional component of pain because they lack a neo-cortex. However, there are many examples of different brain structures performing similar roles in different species.…”

Brydges NM, Braithwaite VA. Measuring Animal Welfare: What Can Cognition Contribute? ARBS Annu Rev Biomed Sci 2008;10:T91-T103. In this review, we explore a variety of techniques that are currently available to investigate the welfare of non-human animals (referred to from now on as animals) with a particular focus on studies of animal cognition. We consider some of the more traditional measures of animal welfare: biological function, physiology and inference, and discuss different ways in which we might assess welfare requirements. We then consider whether cognitive assays can help us determine what animals want or prefer, and whether it is possible to use cognition to discover the mental or affective state of an animal (i.e. positive or negative affective states). We defend that certain aspects of cognition will play a fruitful role in helping us to understand animal 'mental welfare' and, in this way, we make a case for how cognition can be usefully applied in a welfare context.
