Fish population density in Rybinsk Reservoir pelagic area

Abstract

The density of individual species and the total density of pelagic fishes at stations in the Rybinsk Reservoir was evaluated in 1991, 1994, 2006, and 2007. A reliable difference was found to exist between the total fish density in pelagic areas in the 1990s and the 2000s. The density of many species (smelt, zander, perch, and zope) showed considerable variations in both abundance and biomass.
