本文进行了大弹涂鱼室内人工繁殖和育苗研究.性激素注射雌性亲鱼864尾,雄性亲鱼846尾,以陶瓷管道诱导产卵和人工授精的方法获得受精卵,采用塑料箱和塑料桶两种容器孵化受精卵,比较了不同的仔稚鱼培育密度和培育方法与成活率的关系.研究结果表明,雌鱼的催熟率为40.0%～65.0%;管道产卵率为10.0%～26.0%,管道内卵子的平均受精率为60.0%～75.0%,人工授精卵平均受精率为45.0%～65.0%;管道内卵子在塑料箱内的孵化率为17.8%～28.0%,人工授精卵在塑料桶内的孵化率为38.5%～57.0%;共投放初孵仔鱼264000尾,经42～46d培育后变态为幼鱼,共培育出幼鱼31098尾,幼鱼平均全长为1.89cm,平均成活率为11.78%.
In this paper, artificial breeding and nursery research were conducted in indoor labs with large bouncy fish.The sex hormones were injected into 864 female broodstocks and 846 male broodstock to obtain fertilized eggs by means of ceramic tube-induced spawning and artificial insemination. The eggs were incubated in plastic containers and plastic barrels The results showed that the rate of ripening of female was 40.0% ~ 65.0%, the rate of spawning of pipe was 10.0% ~ 26.0% The average fertilization rate of eggs was 60.0% -75.0%, and the average fertilization rate of artificial insemination eggs was 45.0% -65.0%. The hatching rate of eggs in the plastic box was 17.8% -28.0% The hatching rate was 38.5% -57.0%. 264000 tails of newly hatched larvae were planted and transformed into larvae after 42-46 days. 31087 tails of juveniles were co-cultivated with the average length of 1.89cm and the average survival rate of 11.78 %.
