Effects of nutritional status and environmental factors on the endocrine regulation of feeding in freshwater fish

In fish, food intake is ultimately regulated by feeding centers of the brain, which receive and process information from endocrine signals from both brain and peripheral tissues such as the gastrointestinal tract. These endocrine signals induce [orexigenic, such as orexin, neuropeptide Y (NPY) and g...

Description
Summary:In fish, food intake is ultimately regulated by feeding centers of the brain, which receive and process information from endocrine signals from both brain and peripheral tissues such as the gastrointestinal tract. These endocrine signals induce [orexigenic, such as orexin, neuropeptide Y (NPY) and ghrelin] or inhibit  [anorexigenic, such as cocaine and amphetamine regulated transcript (CART), leptin, peptide Y (PYY), cholecystokinin (CCK), proopiomelanocortin (POMC)] food intake, and maintain energy homeostasis (1, 2). Levels of energy stores, feeding status (e.g. fasting) and diet composition, as well as environmental conditions (e.g. temperature, pH, oxygen levels) influence feeding and the expression of endocrine appetite regulators.
