Abstract—Based on the data of trawl surveys, changes in the structure of species composition and flatfish
abundance (Pleuronectidae) in waters off Primorye are shown in the period embracing over 20 years (1983 to
2004). In waters off Primorye, 14 flatfish species were recorded in catches. At the present time, the structure of
the flatfish part of the fish community in waters off Primorye has undergone considerable changes in compari-
son with the 1980s: the proportion of deepwater flatfish has considerably increased against the background of
a decrease in the abundance of coastal species. A general decrease in the numbers and biomass of flatfish in
waters off Primorye is recorded, which is caused by natural reasons against the background of an inconsiderable
fishery intensity.
