摘要
通过生物技术调控棘胸蛙繁殖,可提前并能集中产卵,达到同步孵化、批量出苗的目的。采用生殖激素绒毛膜促性腺激素(HCG)和促黄体素释放激素A3(LRH-A3)对棘胸蛙进行人工催产作用。结果表明,HCG对棘胸蛙无催产作用,LRH-A3有明显的催产作用但卵受精不完全,而二者的组合处理不但催产作用明显,且卵受精完全。在4—6月用HCG+LRH-A3激素组合催产后,棘胸蛙卵至变态为幼蛙的时间为73～89天,均在9月以前完成由蝌蚪至幼蛙的变态。用HCG+LRH-A3激素组合对棘胸蛙进行生物调控,可以在实际生产中推广应用。
The reproduction of Rarta spinosa David was artificially controlled by using biotechnology, in order to advance and centralize the ovulation, synchronize incubation and batch breeding of tadpole. HCG and LRH-A3 were used to make artificial inducing spawning of R. spinosa. No inducing effect of HCG was found on spawning of R. spinosa. LRH-A3 had obvious effect on spawning, but the insemination of R. spinosa was inadequacy. The combination of HCG and LRH-A3 not only had significant function on spawning, but also made complete insemination. After treated with HCG＋LRH-A3 in April to June, the growth time from spawn to young frog was 73-89 d, all before September. The combination of HCG and LRH-A3 could be used to artificial control R, spinosa in practical breeding.
