摘　　要：选择条件相同的面积均为0.30hm^2的6口池塘,分别采用直接发塘培育法(对照组)和分级培育法(试验组)进行黄颡鱼(Pseudobagrus fulvidraco)大规格苗种培育对比试验,黄颡鱼水花放养密度为300万尾/hm^2。经过60d的培育,结果表明:对照组的3口鱼塘黄颡鱼平均成活率为40.43%,平均规格为8.18cm,平均产量为9576.30kg/hm^2;试验组的3口鱼塘平均成活率为60.38%,平均规格为9.44cm,平均产量为18072.8kg/hm^2。由此可见分级培育法要优于直接发塘培育法。Large-sized Pelteobagrus fulvidraco larvae were cultivated with direct cultivation method(control group)and graded cultivation method(experimental group)in six 0.3hm2 ponds under the same condition.The stocking density of P.fulvidraco was three million fries/hm^2.According to the results,after 60 dof cultivation,the average survival rate of P.fulvidraco larvae in three ponds of the control group reached 40.43%,with an average size of 8.18 cm and an average yield of 9576.30kg/hm^2;the average survival rate of P.fulvidraco larvae in three ponds of the experimental group reached 60.38%,with an average size of 9.44 cm and an average yield of 18072.88kg/hm^2.In conclusion,the graded cultivation method was superior to the direct cultivation method.
