摘　　要：为了给平原人工驯养棘胸蛙提供种苗及培育蝌蚪回归大自然以保持生态平衡的需要，本课题从１９８７年起开展生殖激素对棘胸蛙人工催熟、催情、催产作用研究，筛选出高效的催产剂ＬＲＨＡ３。四年来共进行２５次试验，催产率达４５．５％～１００％，受精率７０％～９９．３％，获得受精卵１．２万余粒，培育蝌蚪０．８万尾，相当一部分已成长到中蛙。课题还对受精卵的培育，蝌蚪的饲养作了研究。Gonadotrophin has been used as a general oxytocin for toad and other frogs. Few experiments have been done on the Rana spinosa David. Since 1987, some Gonadotrophins have been used to induce the ovulation of R. spinosa. Results showed that LRH-A3 was very efficient. 25 experiments were done in 4 years. The ovulation rate was 44. 5 % ￣ 100 %, fertilized rate was 70% ￣ 99. 3%. 12 thousand fertilized spawn-eggs and 8 thousand hatched tadpoles have been obtained since 1987. Among which, some of them have changed into middle frogs and were active in artificial ecosystem.
