title: [Effect of food deprivation on quantitative and time characteristics of feeding of goldfish Carassius auratus in norm and under action of adrenaline].
abstract: There was studied effect of intraperitoneally administered adrenaline (0.14 mg/kg) on volume and time characteristics of feeding (duration of single, grouped, and total nutrition) of goldfish Carassius auratus (L.) previously maintained on normal and restricted (for 10 and 15 days) diet. The fish on restricted diet demonstrated the biphasic alimentary response to the adrenaline administration, similar with that in the normally fed fish: a decrease of volume, duration of the grouped and total feeding at the first phase of action of hormone and an increase--at the second phase; however, the value of the response at the first phase of the hormone action was lower, whereas at the second phase--higher than in the fish obtaining a sufficient amount of food prior to the experiment. Duration of the single feeding rose in fish of all groups including the control one, the maximum increase being observed in the goldfish submitted to food deprivation. The glycogen content in hepatopancreas of the normally fed goldfish exceeded by the end of the experiment 4.5-6 times that in the food-deprived ones. The obtained results confirm suggestion that a decrease of the level of reserve substances in the body leads to a decrease of the fish receptivity to the stress hormone--adrenaline and, hence, to a change of the value of its effects on the food-searching goldfish activity, with preservation of dynamics of the parameters.
