摘要：

Triploid was induced by hydrostatic pressure in Pseudosciaena crocea. Pressure shock of 500kg·cm-2 was administered to eggs for 2 min at 3 min after fertilization. The triploid rate was 92.1%. The nucleus diameters （major axes） and volumes of erythrocytes in triploid were measured respectively 1.28 and 1.70 times those in diploid. The triploid growth rates （body length, weight） were not significantly different compared to the diploid controls. The gonadal development was studied through tissue section. The result showed that the triploids had undeveloped gonads and were sterile.
