| Description
| - Zooplankton and macroinvertebrates are the main food sources of perch in their first year of life, although older perch may switch to piscivory. However, piscivorous 0+ perch have been also found in a variety of water bodies. Growth of 0+ fish increases significanly when fish switch from feeding on zooplankton or benthic invertebrates to piscivory. Fish growth is dependent on temperature, food level (including prey type, prey size and its density), and extent of competitive interactions and cannibalism. The growth of fish in their first year of life is an important factor regulating competetive interactions within fish communities and the recruitment of adults. It may affect the structure and dynamics of fish communities with implications for lake food-web structure. In order to understand this early piscivory of 0+ perch, a laboratory study of its growth response was evaluated to answer how different feeding level (zooplanktonic versus fish preys) and predator density may affect growth rate.

- Zooplankton a makrobezobratlí jsou obecně hlavními potravními zdroji okouna během jeho prvního roku života, zatímco starší věkové ročníky mohou přejít na dravý způsob života. 0+ piscivorní okouni byli však nalezeni v mnoha typech vod. Růst 0+ ryb se signifikantně zvyšuje když jedinec přechází z predace na zooplankton nebo bezobratlé na dravý způsob života. Růst ryb je závislý na teplotě, potravních podmínkách (druhu kořisti, její velikosti a početnosti) a výsledcích konkurenčních interakcí a kanibalismu. Růst ryb v jejich prvních roce života je důležitým faktorem regulujícím konkurenční interakce uvnitř společenstva ryb a může ovlivňovat strukturu a dynamiku rybích společenstev s důsledky na složení potravní základny. K porozumnění piscivorie u 0+ okouna byla studována jeho růstová schopnost v laboratorních podmínkách k zodpovězení otázek - jak různé potravní zdroje (zooplankton, ryb) a densita predátora ovlivňují růst. K pokusu byly požiti juvenilní okouni (průměr - 41.7 # 4.4 mm SL) původem z (cs)
