The aim of this experiment was to check the growth rate of the (1+) juvenile sterlet. The experiment was proceeded during the 42-days period (25 July - 4 September 2005) in the hatchery of the Pohořelice Pond Fisheries. The fish were kept in four flow through tanks. In total, 45 individuals were stocked in each tank. Fish were fed by experimental (44/12) and commercial diet (Pro Aqua Brutfutter 57/15, Skretting) in two repetitions. Our experiment confirmed very good growth ability of the juvenile sterlet, together with low FCR parameter. Sterlet may be considered as an appropriate fish for intensive aquaculture and also, as a native species of the Czech Republic for stocking into Czech running waters.
