Abstract
[Objective]The purpose of the research was to find a feasible sex control technology for culturing Rana chensinensis artificially. [Method]The control technologies with drug, temperature and ions were used in the sex induction of R. chensinensis and the sex induction technology suitable for culturing R. chensinensis artificially was selected out. [Result]All the 57 tadpoles induced by 100 μg/L estrogen differentiated to be female. Among the 32 tadpoles induced by 500 μg/L estrogen, there were 23 tadpoles differentiated to be intermediate gender and 9 tadpoles differentiated to be holandry. Among the 25 tadpoles induced by 1 000 μg/L estrogen, there were 21 tadpoles differentiated to be holandry and 4 tadpoles differentiated to be intermediate gender. When the ion content was l 500 mg/L, the individual average body length and body weight were increased most and the differentiation proportion of female frogs was enhanced from 46.7% to 82.4%. When the ion content was higher or lower than 1 500 mg/L, the increments of individual average body length and body weight were decreased. The water temperature in hiruike could not exceed 12 ℃ in early May, could not exceed 15 ℃ in middle May, could not exceed 18 ℃ in early Jun. and could not exceed 20 ℃ in middle Jun. [Conclusion]The research provided technical support for culturing R. chensinensis artificially.关键词
