翘嘴鳜的人工繁殖与胚胎发育观察
Artificial Propagation and Embryonic Development Observation of Mandarin Fish
【摘要】 采用不同配伍外源激素对性成熟翘嘴鳜催情,发现:20~24°C下,催产素PG+LRH-A+HCG的效应时间更短;25~29°C下,则催产素PG+HCG效应时间更短。采用人工受精的方法获得受精卵,在水温18~22°C观察翘嘴鳜胚胎发育的时序和特点,从受精卵发育到破膜仔鱼经过了68h17min;翘嘴鳜胚胎发育可分为7个阶段26个时期。文章还详细记录了翘嘴鳜胚胎发育各个阶段的形态特征。
【Abstract】 Different compatibility oxytocin was used in mandarin fish to reach sexual maturity,it is found that in 20~24 °C,PG+LRH-A+HCG had more shorter effective time;and in 25~29 °C,PG+HCG had shorter effective time.In this study,artificial insemination way was used to get the zygote,and observed the time sequence and characteristics of the embryonic development,with the water temperature being from 18 °C to 22 °C.It took 68 hours 17 minutes for zygote to develop to newly hatched larve.Siniperca chuatsi embryonic development can be divided into seven stages,26 periods.
【Key words】 mandarin fish(Siniperca chuatsi); embryonic development; artificial propagation;
