摘要
中间球海胆 (Strongylocentrotusintermedius)八腕后期幼虫 ,在KCl添加浓度 10 0mmol/L海水中 ,分别处理 5 ,10 ,15min后 ,均变态为正常稚海胆。中间试验及生产应用结果表明 ,经KCl处理 ,幼虫的附着时间缩短了 36h ,附着率则分别增加了 40 4% ,2 7 7%。
This paper studied the effect of KCl on the larval metamorphosis of the sea urchin Strongylocentrotus intermidius .The larvae were induced normally by exposure to sea water supplemented with KCl concentrations of 100 mmol/L within 5 min,10 min,15 min,respectively.The result show,on the medial examinations and the applications of large-scale production,the settling time of the larvae of sea urchin Strongylocentrotus intermidius are shortened 36h and the rate of their settling are increased 40 4% and 27 7%,respectively,when the larvae are induced metamorphose by exposure to sea water supplemented with KCl.
