Název v původním jazyce

The effect of depth, distance from dam and habitat on spatial distribution of fish in an artificial reservoir

Popis výsledku v původním jazyce

Spatial distribution of fish community in the Římov Reservoir was studied in 1999?2007. Effects of depth, distance from dam to the tributary and habitat type on fish community characteristics were tested. Fish were recorded in all depths and parts of reservoir. Effects of environmental variables were significant and most variability was explained by depth, then by distance from dam and habitat type. CPUE and BPUE of all species decreased with depth and responses of individual species to depth were similar for juvenile and adult fish. Number of species, CPUE and BPUE of all species except perch increased heading towards the tributary. Responses of juvenile fish to distance from dam differed from that of adult fish. Structure of fish community differed in benthic and pelagic habitats with species preferably occupying epipelagic (bleak, asp, rudd and juvenile bleak, roach and bream) or littoral waters (perch, pikeperch, ruffe, roach, bream and juvenile percids).
