摘 要:[目的]了解棘胸蛙蝌蚪胚后发育变化过程及蝌蚪饲养技术。[方法]采用模拟生境法,对粤北天井山林场棘胸蛙蝌蚪进行人工饲养,观察发育状况,并与自然环境下的蝌蚪进行对比。[结果]蝌蚪从卵膜孵化后需31~32 d才进入胚后发育。蝌蚪胚后发育共需60~61 d,其中26~30期需12~17 d、31~37期需24~26 d、38~41期需9~13 d、42~46期需11~12 d。蝌蚪自孵化出膜经91~92 d可变态成幼蛙。经独立样本T检验,该试验饲养的蝌蚪与野外自然环境下相同分期的蝌蚪,头体长及全长总体平均值之间差异不显著。[结论]采用模拟生境法,人工饲养的蝌蚪发育正常,饲养状况良好。[Objective] The aim was to study the feed technology of tadpole and postembryonic development of Paa spinosa tadpole.[Method] Through simulating the ecological environment to feed Paa spinosa tadpole in Tianjinshan tree farm of North Guangdong,then,observing the development condition and comparing with tadpole in the natural environment.[Result] It took about 31-32 days for tadpole to develop from incubation to postembryonic development and 60-61 days to complete the postembryonic development.It included 12-17 days to complete 26-30 stages,24-26 days to complete 31-37 stages,9-13 days to complete 38-41 stages,11-12 days to complete 42-46 stages.From incubation to froglet,it needed 91-92 days.There was no significant deference in body size between the captive and natural tadpoles in the same stage by independent sample T test.[Conclusion] Using simulation of ecological environment,the results indicated that the growth of captive tadpole was normal and the living conditions were good.
