Two replicates per treatment were applied. These three methods were evaluated regarding specific growth rate (SGR), condition coefficient (K), survival and cannibalism. Mean initial total length (TL) of fish was 35.22 ± 2.15 mm and mean individual weight (w) was 0.31 ± 0.05 g. There were 600 individuals in each circular tank. The initial stock density was 2 fish.l<sup>-1</sup>. Fish survival during a 14-day period of rearing ranged from 34.33 % (variant C) to 50.33 % (variant A). Significantly (P &lt; 0.05) better conversion performance was achieved with variants A and B than with the variant C regarding all parameters.
