【Abstract】 The methods of artificial rearing and artificial induced metamorphosis of larvae and juveniles of Anthocidaris crassispina is reported in this paper. Its planktonic larvae can be divided into 5 phase, i.e. Prism larvae, Two arm larvae, Four arm larvae, Six arm larvae and Eight arm larvae, and take 11d to complete these changes. The chaetoceros muelleri is found to be a suitable. But the young urchin shows preference to benthonic diatom. The maximum shell diameter of young urchin gets 1.5 mm when the period of rearing is one month. The transparent plate from PE is the suitable material for young urchin to adhibit.[WT5F1]更多还原
