Dynamics of the size and age composition of the arabesque greenling Pleurogrammus azonus in the pelagial of the russian waters in the sea of Japan

Abstract

In the pelagial of the Russian waters of the Sea of Japan, juveniles and adults of the Arabesque greenling Pleurogrammus azonus are found from March to November. The average size of fingerlings of Arabesque greenling increase from South to North. Larger sizes of fingerlings in the north are determined by earlier spawning, compared to the south. Density aggregations of Arabesque greenling in the pelagic zone is much smaller than in the bottom layers of water. High migration activity is characteristic of a smaller hart of individuals.
