南海海域三疣梭子蟹的幼体培育Larval Rearing of Portunus trituberculatus in the South Sea of China

摘要(Abstract)：
幼体期Z1和Z2投喂扁藻和轮虫,Z2后期开始以轮虫和卤虫无节幼体混合投喂,Z3后用卤虫无节幼体投喂,大眼幼体用不同饵料培育,进行南海海域三疣梭子蟹幼体培育,结果表明:溞状幼体平均成活率为15.3%;Z2变态为Z3、Z4变态为M为溞状幼体培育的敏感期,幼体的阶段成活率较低;以卤虫无节幼体、冰冻卤虫成虫、活卤虫成虫为饵料,均能使培育大眼幼体至幼蟹,其中活卤虫成虫投喂、加防残网片培育效果最好,成活率达80%。
