Paper represents results for research related to paddlefish and sterlet rearing technology optimization. Obtained data allows us to state that stocking ponds with larva having average individual bodymass (AIB) as much as 135mg leads to receiving sterlet fingerlings with AIB 2.7-3.5g, survival rate – 62.1- 65.8%, fish productivity – 138.6 kg/ha. Maximum results for paddlefish such as survival rate (29.3%), AIB (278g) and fish productivity were obtained while stocking ponds with 800mg larva
