The appropriate choice and intake of food and nutrients have a great beneficial impact on health, growth, reproduction and lifespan of fish. Nevertheless, nutritional requirements vary according to the life cycle and physiological status of animals. Feeding is a complex behavior regulated by neuroendocrine/endocrine signals from the brain and periphery, in which hypothalamic neuroendocrine factors such as neuropeptide Y, agouti-related neuropeptides, proopiomelanocortin and cocaine- and amphetamine-regulated transcript peptides, among others, could play an important role. In addition to the “classical” neuroendocrine factors (e.g., gonadotropin-releasing hormone, dopamine, kisspeptins, GABA, serotonin, neuropeptide Y…), new actors as gonadotropin-inhibitory hormone, spexins, neurokinins/tachykinins and secretoneurins have gained increasing importance in the regulation of fish reproduction over the last decades. It is interesting to note that some of these neuroendocrine factors could modulate food intake and gonadal development/maturation and reproductive performance through the hypothalamic-pituitary-gonadal-liver axis. The present Research Topic aims to provide an updated vision on the neuroendocrine regulation of fish feeding and reproduction, with emphasis on those factors modulating both physiological processes.
The main objective of the present Research Topic is to provide a comprehensive and updated vision on the neuroendocrine control of feeding and reproduction in fish, focusing especially on the factors that could modulate both physiological processes. The Research Topic welcomes original and review articles reporting recent advances in physiological actions, brain distribution, signaling pathways and regulatory patterns, such as transcriptional regulation and epigenetic modification, of neuroendocrine systems modulating feeding and reproduction in fish.
1. Novel neuropeptides that could play a modulatory role in both feeding and reproduction in fish: physiological, molecular and neuroanatomical evidences of its actions and interactions.
2. Novel signaling pathways and regulatory patterns, such as transcriptional regulation and epigenetic modification, of neuroendocrine systems modulating feeding.
3. Functional significance and signaling pathways of neuroendocrine factors involved in the regulation of reproduction (such as GnIH, kisspeptin, spexin, neurokinin B, secretoneurin).
