Description
| - The diet changes in gillnet catch rates and vertical distributions of pelagic fishes were determined in a deep, moderately eutrophic European reservoir. In late summer, when steep vertical gradients in temperature and dissolved oxygen developed in the reservoir, monofilament gillnets (12.5-70 mm bar mesh) covering the upper 7.5 m of the water column were set at two open-water locations over 44- and 46-h periods, respectively. Gillnets divided the sampled strata (i.e., the epilimnion and metalimnion) into five horizontal layers each 1.5 m thick. Captured fish were removed from the nets at regular 2-h intervals. The catches were numerically dominated by bleak Alburnus alburnus, roach Rutilus rutilus, perch Perca fluviatilis, bream Abramis brama and asp Aspius aspius. Catch rates varied considerably with the time of day. The total gillnet catch per 2-h was on average 3-4 times higher at twilight than during the day or at night. Decreased net visibility and increased fish activity were likely responsible
