Brain regulation of growth hormone secretion and food intake in fish

Abstract

Growth in fish is regulated by the brain neuroendocrine—growth hormone (GH)— insulin-like growth factor axis (Peter and Marchant, 1995; Peng and Peter, 1997). However, growth cannot be realized without adequate food intake. A question to be answered in fish is whether there is any connection between the regulation of food intake and the brain neuroendocrine — GH — insulin-like growth factor axis. An additional question of relevance to aquaculture is whether the brain neuroendocrine — GH — insulin-like growth factor axis and food intake can be manipulated to stimulate faster growth rates of farmed fish?
