摘要
为石斑鱼种间杂交经济型利用提供基础资料,以云纹石斑鱼为母本,赤点石斑鱼为父本进行种间远源杂交,对杂交子一代的生长及越冬作了系统观察。结果表明,用人工授精的方法可以取得杂交受精卵,受精卵的受精率、孵化率均在90%左右,杂交子一代比对照组仔鱼畸形率高;杂交子一代的生长趋势接近母本云纹石斑鱼,体色接近父本赤点石斑鱼,在室内可以正常越冬。云纹石斑鱼♀与赤点石斑鱼♂进行经济型杂交是可行的。
The research aimed to provide basic data for the interspecific hybridization economy utilization of grouper species. We conducted hybridization between Epinephelus moara （ ♀ ） and Epinephelus akaara （ ♂ ） by artificial methods. The growth and wintering were made systematic observations of the hybrid F1. Rate of fertilized eggs and rate of hatched eggs were about 90%. Rate of abnormal larva of hybrid was higher compared the control group. The growth trend in hybrid F1 was close to female Epinephelus moara, and the body color in hybrid F1 was close to paternal Epinephelus akaara. The hybrid F1 could live through the winter nor-mally and they could be utilized in the aquaculture production in the future.
