| Description
| - Size-related changes in diet of perch (Perca fluviatilis L.) and pikeperch (Sander lucioperca L.) were studied throughout their first year of life until the fry reached about 30 mm SL. In general, ontogenetical changes in diet were similar in both species. Smallest larvae (< 9.5 mm SL) consumed predominantly nauplii and copepodite instars of cyclopoid and calanoid copepods. Rotifers played minor role, especially when evaluating their biomass contribution, but in very low numbers occurred also in the diet of pikeperch larger than 20 mm SL. Cladocerans - Daphnia galeata and Diaphanosoma brachyurum appeared already in the diet of the smallest fry, but their importance increased once the fry reached about 15 mm SL and from that body length especially Daphnia spp. were the most important part of the diet of both species. Even in the largest fry group no piscivorous perch or pikeperch were reported. In the second part of the study pikeperch piscivory is disscussed on an example of case study of its pond

- Změny v potravě v průběhu ontogeneze byly studovány u 0+ okouna (Perca fluviatilis ) a candáta (Sander lucioperca ) až do dosažení cca. 30 mm celkové délky těla a ukazují na velice podobnou potravní biologii u obou druhů. Nejmenší larvy (< 9,5 mm SL) konzumovaly především nauplia a kopepoditová stádia klanonožců (Calanoida, Cyclopoida). Vířníci nepatřily mezi významnou potravní skupinu zvláště se zřetelem k jejich dostupné biomase, ale ve velmi malém podílu se vyskytovali i u jedinců candáta větších než 20 mm SL. Perloočky - Daphnia galeata a Diaphanosoma brachyurum se vyskytovaly v potravě již u nejmenšího sledovaného plůdku, ale jejich významnost se zvyšovala teprve po dosáhnutí délky těla nad 15 mm. Od této délky tvořili nejvýznamnější složku potravy u obou druhů zástupci rodu Daphnia spp. Ani u největšího plůdku nebyly v potravě zaznamenány ryby. Druhou část práce tvoří nastínění skutečností doprovázených přechodem na piscivorii na příkladu monokulturního odchovu ročka candáta. Rozdíly v (cs)
