Feeding of small-sized European perch, Perca fluviatilis, in a littoral zone of a restored lake

摘要: Abstract The study focuses on the feeding of small-sized European perch, Perca fluviatilis, in a lake after stocking with predatory fish and their effect zooplankton view ongoing restoration. It has been assumed that predator-prey interactions should lead to increased trophic activity perch littoral zone. studies were carried out from June October 2008. results catches indicated small eliminated open water recorded only zone lake. In diet, total 19 food items found, primarily represented by invertebrates: Cladocera, Copepoda, Diptera sporadically Rotifera. Herbivorous forms, i.e. Calanoida or Daphnia sp., frequently picked as (F = 40–50%). most important component was zooplankton, which accounted, average, for 90% numbers consumed animals nearly 65% terms mass. Cladocera constituted larger part selected than but late spring partly summer. Significant pressure large filterfeeders genus is expected periodically.
