Physiological parameters and problems of energy budget estimation in mediterranean and balck sea fishes

摘要

During several expeditions in Mediterranean in 1970-1980s on the scientific vessel Adademic Kovalevsky (Institute of the Biology of the Sourthern Seas, Sevastopol) some parameters of energy metabolism of fishes were studied. It was shown that fat (triacylglicerol) accumulation, their utilization for energy metabolism, effect of food supply on these processes in Mediterranean fishes have features of similarity and difference with Black Sea ones. Principal scheme of energy balance for Black Sea fishes may be used for Mediterranean ones. At the exumple of horse mackerel Trachurus mediterranus energy consumption, utilization, expenditure for growth and metabolism was analysed, Intensity and efficiency of porduction formation was studied. Such investigation has perspectives for estination of energy and substance balance (budjet) not only for mass species of fishes but invertebrate animals of both water bodies too.
