虾夷马粪球海胆 (Strongylocentrotusintermedius)人工育苗中 ,亲胆采用 0 5mol/LKCl溶液围口膜注射法催产 ,孵化密度 2 0～ 30个 /ml,个体培育期间以投喂角刺藻效果最好。当幼虫培育积温达 36 7～ 36 9℃ (约 2 0～2 1d)附着变态 ,平均变态率为 2 6 9%。共得稚胆 334万枚。
In the artificial breeding of Strongylocentrotus intermedius, the density of 20 ~ 30 / ml of hatchling was induced by the injection of 0 5mol / L KCl into the sea urchin. . When the larvae incubation temperature reached 36 7 ~ 36 9 ℃ (about 20 ~ 21d) metamorphosis, the average metamorphosis rate of 269%. A total of 3.34 million naive children.
