“…A number of different fish behavioural patterns have been related to this defensive system (Huntingford et al, 2006;Ashley & Sneddon, 2008). In response to a threatening event, they may include protective motor reactions like flee, hide or shoaling.…”

“…They are capable of highly flexible and specialised behaviour, depending from complex neuroendocrine, cognitive and emotional processes (for reviews see Bshary et al, 2002;Braithwaite & Huntingford, 2004;Chandroo et al, 2004a;Ashley & Sneddon, 2008;Braithwaite & Boulcott, 2008).…”

“…They found that morphine had an analgesic effect, reducing pain-related behaviours and opercular beat. Ashley and Sneddon (2008) reviewed studies involving opiate production, as mediators of nociception and pain, and their specific receptors in fish. Sneddon and her team (2003b) have shown how familiarisation with novel objects can reduce the typical fear response of rainbow trout (as described above).…”

“…Yue and colleagues (2004) have shown how the behavioural responses of rainbow trout to fearful stimuli are of a non-reflexive nature and how they can make conscious choices to avoid future frightening stimuli. Ashley and Sneddon (2008) review studies where the administration of benzodiazepines (anti-anxiety drugs) to fish can reduce the typical fear response.…”

“…Due to the lack of language, the subjective state of a given emotion cannot be studied in animals in the same way as it is in humans. Therefore, the correspondent physiological and behavioural responses are the focus of the research on emotions (Ashley & Sneddon, 2008).…”

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.
