| Description
| - The study of perch fry food biology in polyculture with carp and parental fish was performed with fish originating from natural pond spawning. Zoobenthos was the main food resource of perch fry, particularly chironomid larvae supplemented by zooplankton (mostly cladocerans Bosmina longirostris, Chydorus sp., Ceriodaphnia sp., Alona sp. and copepods). Chironomid larvae and cladocerans showed the positive coefficients of selectivity. Perch fry > 25 mm did not consume rotifers. Chironomid larvae were also the most important food item of 2+ carp and adult perch. Cannibalistic nutrition with respect to their own progeny was registered in adult perch. Food similarity (= competition) between perch fry and adults amounted to 33.2% and between perch fry and 2+ carp fluctuated between 2.3 - 34.8%. Adult perch and carp compete in 50.0% range.

- Studie potravní biologie plůdku okouna v polykultuře s kaprem a rodičovskými rybami byla provedena na rybách pocházejících z přirozeného výtěru v rybníce. Základ potravy plůdku okouna tvořil zoobentos, hlavně larvy pakomárů (Chironomidae), zooplankton, především perloočky (Bosmina longirostris, Chydorus sp., Ceriodaphnia sp., Alona sp.) a klanonožci. Larvy pakomárů a perloočky vykazovaly rovněž pozitivní koeficienty selektivity. Plůdek okouna ve velikosti nad 25 mm již nekonzumoval vířníky (Rotatoria). Larvy pakomárů byly nejvýznamnější potravní složkou rovněž kapra 2+ a adultních okounů. V potravě dospělých okounů se však často objevovalo rovněž vlastní potomstvo. Potravní shoda (= kompetice) mezi plůdkem a dospělými okouny činila 33,2% a mezi plůdkem okouna a kaprem se pohybovala mezi 2,3 - 34,8%. Adultní okoun a 2+ kapr si však konkurují v 50,0% rozsahu.
