A comparative study on the feeding of eel, , (L.), bream, , (L.) and ruffe, , (L.) in Lake Võrtsjärv interactions would arise only in case of limited food resources in the years with a low biomass of . A significant correlation (.= 0.88; . < 0.05) was found between the mean biomass of fourth-instar larvae of . in the lake sediment and in the stomach of ruffe in different years. The diet compositio

Habitat use and recruitment: a comparison of long-term recruitment patterns among fish species in a on by walleye by YOY yellow perch, and (3) correlation with water temperature and productivity (indexed through total phosphorus levels, TP). Buffering from predation by walleye was likely important for the species in the first group, as indicated by positive correlations between inter-annual abunda

Hydrothermodynamic features of mass exchange across the sediment-water interface in shallow lakesolumes with positive buoyancy. The effectiveness of such mass transfer is several orders greater than that of molecular diffusion. This hypothesis was checked by special field and laboratory experiments which were carried out on shallow Lake Krasnoye. The mathematical model of this phenomenon was de
