Abstract

somatostat; glucagon S such as sul and glucagon are known to fluence the nutritional metabolism of fish (1, 16). sul is a potent anabolic agent that has been observed to stimulate amo acid and glucose uptake and enhance glycogen synthesis salmon vitro (17). sul also decreases plasma fatty acids and hepatic triacylglycerol hydrolysis salmon (28). Glucagon stimulates mobilization of hepatic glycogen and lipids as well as hepatic gluconeogenesis (16). The secretory activity of pancreatic islets results traislet coordation as well as control of peripheral metabolic actions; such effects fe-tune the nutritional physiology of the organism. For example, glucagon and somatostat-25 (the PANCREATIC 0363-6119/91 $1.50 predomate form of somatostat the pancreas of salmon, a product of somatostat gene II; cf. Ref. 20) has been shown to reduce sul titers (19, 29). The fluence of nutritional state on the secretory activity of the endocre pancreas of fish has been evaluated by a number of experiments. Recently, fasted salmon and have been shown to exhibit reduced plasma sul and plasma glucagon concentrations; however, sul levels were depressed relatively more than glucagon levels (13, 27). Normal glycemic levels mataed fasted salmon for up to 3 wk are supported, part, by hepatic glycogen
