The heterosis estimates for growth and survival traits in sterlet and Siberian sturgeon purebreds and hybrids
Original language description
The aim of the present study was to estimate and compare the growth and survival traits of the hybrids and purebreds produced by crossing the Siberian sturgeon (Acipenser baerii) (S) and sterlet (Acipenser ruthenus) (St) in order to determine the heterosis effect in the F1 generation. We compared the breeding conditions, mean body weight (BW) and cumulative survival in the artificially produced hybrid crosses of sterlet and Siberian sturgeon with respect to their pure parental species in indoor and outdoor aquaculture systems at different developmental stages. Fertilization and hatching rates were found to be significantly higher in S x S purebred compared to St x S hybrid. The highest values of BW were recorded in St x S hybrid (557.54 +/- 179.7 g) on 862 days post-hatch (dph) while the highest cumulative survival was recorded in S x S purebred (14.3%). The recorded cumulative survival and mean BW was significantly lower in St x St purebred. The highest positive heterosis was recorded for mean BW of St x S hybrid (51.3% on 862 dph) throughout the sampling points. The studied sturgeon hybrids had higher mean BW compared to St x St purebred under suboptimal rearing conditions. Although there was no clear demonstration of the superiority in performance of reciprocal hybrids over purebreds, the St x S hybrid can be used for achieving better productivity in aquaculture systems.
