The aim of this study was to check the possibilities of exploitation of summer zander (Sander lucioperca) fry for production of stock material under controlled conditions. Two groups of these fish were converted from natural diet to artificial diet using the semi-moist feeding mixtures (variant A) and trout feed (Dan-Ex 1352 - variant B). The average total length of imported fish was 44,3 mm and the average idividual weight was 0,606 g. There were 255 individuals in each tank. The initial stock density was 2,34 g.l-1 (3,86 ks.l-1). The water temperarute during this experiment fluctuated in intervals 21 ů 23 oC. Our simple experiment confirmed possibility of exploitation of summer zander fry to intensive rearing of stock material.
