Growth and Adaptive Significance of Various Forms of Energy Processes in Marine Fishes of Arctic.

Based on expeditions and experimental studies, energy characteristics underlying the interaction of energy exchange processes were assessed quantitatively in fishes of the Arctic. The linear and weight growth was studied for the first time in the nonmigratory species Arctic flounder Liopsetta glacialis (Pallas, 1776) of the Kara Sea. It was found that deceleration of biosynthetic processes leads to a relative decrease in the proportion of entropy generated by metabolic processes in cold-water marine fish species, while the growth becomes more efficient at low temperatures.
