The effect of fish size and stocking density on the weaning success of pond-cultured pikeperch Sander lucioperca L. juveniles

Popis výsledku v původním jazyce

The effect of initial fish size (small with TL = 40.3 +/- A 2.3 mm and W = 0.42 +/- A 0.15 g, medium with TL = 56.2 +/- A 2.7 mm and W = 1.66 +/- A 0.4 g, and big with TL = 71.0 +/- A 3.2 mm and W = 2.95 +/- A 0.65 g) and stocking density of identical fish with TL = 40.3 +/- A 2.3 mm and W = 0.42 +/- A 0.15 g (1; 2; 4; 8 fish l(-1)) on weaning success was evaluated in pond-cultured pikeperch. The trial was divided into weaning (12 days) and post-weaning (16 days) periods. Small juveniles reached significantly higher specific growth rate (SGR = 1.6 +/- A 0.2 % day(-1)) and survival rate (S = 81.7 +/- A 2.7 %) and lower cannibalism (C = 3.0 +/- A 0.75 %) compared to medium and large juveniles (SGR = 0.3-0.5 % day(-1), S = 65.3-76.5 %, C = 6.5-7.5 %) during the weaning period. The higher survival rate was found at the two higher densities (S = 72.0-79.1 %) during the weaning period. The lowest survival rate (S = 38.9 +/- A 2.7) was observed at the lowest fish density.
