Feeding strategies and resource utilization of 0+ perch, Perca fluviatilis L., in littoral zones of shallow lakes

摘要

Feeding strategies and resource utilization of 0+ perch, Perca fluviatilis L., in littoral zones of shallow lakesThe aim of the study was to analyze the diet and feeding strategies of 0+ perch, Perca fluviatilis L., in two lakes (Gos?awskie and Do?gie Wielkie) with different trophic and thermal regimes. Water temperature was higher in Lake Gos?awskie (Mann-Whitney test, PSida crystallina, larval Chironomidae). Perch feeding intensity in Lake Do?gie Wielkie was positively correlated with body length, while in Lake Gos?awskie it remained at the same level.
