No reason for keeping 0+perch (Perca fluviatilis L.) with the prey fish

Popis výsledku v původním jazyce

Growth and survival of 0+ perch were studied in 4 ponds with the topmouth gudgeon (Pseudorasbora parva) and without it. In the end of April, all ponds were stocked by free-swimming perch larvae (120,000 ind ha(-1)). In June, topmouth gudgeon was introduced as forage fish (40 kg ha(-1)) into two of the experimental ponds. Topmouth gudgeon significantly influenced neither the total abundance of zooplankton nor the abundance of its groups (Rotifera, Cladocera, Copepoda). The most important food item for perch (TL } 29 mm) was macroinvertebrates (especially Chironomidae). In the ponds with topmouth gudgeon, copepods and cladocerans were more important than in ponds without it. Specific growth rate of perch was 0.01 mm day(-1) in all ponds. Final mean totallength (TL +/- A SD) of perch was 73 +/- A 13 and 70 +/- A 6 mm in the ponds with topmouth gudgeon and without it, respectively. Only 1 % of the perch reached higher TL than that recorded in the ponds without the topmouth gudgeon. Surviv
