Kolpakov, P. Milovankin] The distribution and seasonal dynamics of fish abundance in the estuary of the Razdol'naya River (Peter the Great Bay) depending on several abiotic factors are considered. It is established that fish biomass increases with an increase in salinity and decrease in water temperature (both in space and time). Freshwater stenohaline species dominate in the upper part of the estuary, semianadromous and freshwater euryhaline species dominate in the middle part, and semianadromous and marine species dominate in the lower part. The seasonal succession of ichthyocenosis includes two periods: warm (May-October) and cold (November-April). The warm period is characterized by a low biomass (4-10 g/m2) and maximum species richness (22-29 species) against the background of a decrease of the penetration into the estuary of high-saline waters and an increase in the water discharge, turbidity, and temperature. Freshwater species dominate in catches, and subtropical migrants appear. In the cold period, species richness is minimal (2-12 species), and biomass is, on the contrary, very high (on average, 71-374 g/m2); water temperature and discharge are minimal. In catches, the proportion of semianadromous and marine species is maximum.
