黄颡鱼“全雄1号”与黄颡鱼饲养效果对比分析

Contrast research on cultivating of “All-male No. 1 ” and ordinary Pseudobagrus fulvidraco

为探索研究鱼池培育黄颡鱼（ Pseudobagrus fulvidraco）“全雄1号”鱼种技术，在四口鱼池中进行了“全雄1号”黄颡鱼和黄颡鱼鱼种培育对比试验。分别向试验鱼池投放规格3～5 cm/尾黄颡鱼“全雄1号”和规格3～5 cm/尾黄颡鱼夏花鱼种。结果表明：黄颡鱼“全雄1号”生产性能优于黄颡鱼，其饲料转化效率高于黄颡鱼、饵料系数比黄颡鱼低20％；黄颡鱼“全雄1号”鱼种单产达到510 kg/667m2，单位利润达到7093元/667m2；黄颡鱼鱼种单产为367.6 kg/667m2，单位利润为3069元/667m2。

In order to explore the cultivating technology of “all-male No.1 ” Pseudobagrus fulvidraco fingerling in fish ponds, comparison experiments on cultivating fingerling of “all-male No.1” P.fulvidraco and ordinary P.fulvidraco were carried out in 4 fish ponds .“All-male No.1” and ordinary P.fulvidraco summerlings of the same stocking size 3~5 cm/fish were stocked respectively in different test ponds . The results showed that the feed coefficient of “all-male No.1”P.fulvidraco was 20%lower than that of ordinary P.fulvidraco.The productions of “ all-male No.1 ” P.fulvidraco were 510 kg/667 m2 , and the profits were 7 093 yuan/667 m2; while the productions of ordinary P.fulvidraco were 367.6 kg/667 m2 , the profits were 3 069 yuan/667 m2 .
