Gonadal development of Siberian Sturgeon ( Acipenser baeri ), Russian Sturgeon ( A.gueldenstaedti ), Amur sturgeon ( A.schrencki ), Heilongjiang Hybrid Sturgeon ( Huso dauricus ♀ × A.schrencki ♂ ) and Europe Hybrid Sturgeon ( H.huso ♀ × A.ruthenus ♂ ) from 12 test groups was observed during November 2007 to November 2009.Their gonads could develop to stage Ⅳduring different seasons, with egg diameter reaching or exceeding 2.8 mm. In February 2009, 5 Siberian Sturgeons and 13 Russian Sturgeons were randomly selected for artificial reproduction, and all were induced to ovulate successfully except one Russian Sturgeon individual, suggesting that sturgeons can be artificially propagated at any seasons throughout a year. Their fecundity had seasonal fluctuations. It was showed that Amur sturgeon, Siberian Sturgeon, Russian Sturgeon and Heilongjiang Hybrid Sturgeon’s fecundity was negatively correlated with their body weight, with correlation coefficients at-0.021 ( P <0.01),-0.159 ( P <0.01),-0.145 ( P <0.01) and-0.062 ( P <0.01), respectively. Fecundity of the European Hybrid Sturgeon was positively related with body weight and the correlation coefficient was 0.051 ( P <0.01).Otherwise, curve fitting of body weight and egg weight showed that the body weight and egg weight were positively correlated in several species of sturgeon. Our results indicate that artificial breeding of all these 5 species of sturgeon is feasible all year round.
