dc.description.abstractNeuropeptides are highly variable but widely conserved molecules, the main functions of which are the regulation and coordination of physiological processes and behaviors. They are synthesized in the nervous system and generally act on other neuronal and non-neuronal tissues or organs. In recent years, diverse neuropeptide isoforms and their receptors have been identified in different fish species, regulating functions in the neuroendocrine (e.g., corticotropin-releasing hormone and arginine vasotocin), immune (e.g., vasoactive intestinal polypeptide and somatostatin), digestive (e.g., neuropeptide Y), and reproductive (e.g., isotocin) systems, as well as in the commensal microbiota. Interestingly, all these processes carried out by neuropeptides are integrated into the nervous system and are manifested externally in the behavior and affective states of fish, thus having an impact on the modulation of these actions. In this sense, the monitoring of neuropeptides may represent a new approach to assess animal welfare, targeting both physiological and affective aspects in fish. Therefore, although there are many studies investigating the action of neuropeptides in a wide range of paradigms, especially in mammals, their study within a fish welfare framework is scarce. To the best of our knowledge, this is the first review that gathers and integrates up-to-date information on neuropeptides from an animal welfare perspective. In this review, we summarize current findings on neuropeptides in fish and discuss their possible implication in the physiological and emotional state of fish, and therefore in their welfare.eng
