【Abstract】 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.更多还原
