Abstract. Arabesque greenling Pleurogrammus azonus is an important commercial species in the waters of Russia and Japan. In the Russian waters of the Japan Sea, regular study of its biology was conducted in the waters of the Primorsky Krai, where annual trawl surveys were performed. Material collections covered the entire calendar year. Endogenous rhythms (internal biological clocks) play a crucial role in the coordination of biorhythms of the Arabesque greenling Pleurogrammus azonus. This assumption is confirmed by the different duration of exogenous and endogenous rhythms: the dynamics of the temperature index has a pronounced periodization equal to one astronomical year, and the duration of the mixed rhythms in the dynamics of physiological processes and main components changes with age. The relationship of somatic and generative growth with temperature oscillation is subjected to age-related variability. In juveniles, this relationship is not clearly traceable. At the beginning of puberty period, significant connections are manifested. Then the dependence of growth indicators on the temperature oscillation is reduced, as the selective ability of the Arabesque greenling to choose the temperature range increases. Selective ability to environmental conditions is largely determined not by individual but by group behavior.
