摘要

Studies conducted in April-October showed that the Japanese sandfish Arctoscopus japonicus occurred in Peter the Great Bay in the near-bottom water layers at a depth of 1.5 to 550 m at a temperature of -0.2 to 16.5 degrees C; however, distribution of the species varied during this period significantly. After a period of pelagic development, young fish with a length (FL) from 3.5 cm pass to the benthic mode of life and leave in July the coastal area. In summer, juveniles live at a depth of approximately 25-55 m; in the autumn, they spread over the shelf. Maturation of some individuals in the first year of life was not observed in the bay; it is typical only for the southern areas of the range. In the warm season, the majority of older fish adhere to the bathymetric range of 40-60 m and adjacent depths. In the autumn, before spawners approach the coast for spawning they descend into deeper waters and penetrate into the lower part of the shelf and onto the continental slope.
