"The aim of our experiment was comparison of two weaning methods of juvenile pikeperch: direct (variant A, dry feed without natural food) and combined (variant B, co-feeding of dry feed and frozen chironomids). Six thousand individuals of juvenile pikeperch with mean initial total length (TL) 38.61 mm, weight (W) 0.45 g and condition factor (K) 1,34 (n = 100, average) from pond were randomly distributed into six plastic tanks in the recirculation system. After 21-day rearing period, the weaning success was evaluated. In the variant B there was achieved significantly higher (p<0,007) survival (58.37%) in comparison with the variant B (27.87%). However, some fish in the variant B preferred only chironomids and did not intake any dry feed. TL of these fish was only 48.23 mm, W 0.76 g and K 1.08.
