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 and study the Pseudobagrus fulvidraco “all male 1 ” fingerling technology, we compared the breeding of “all male 1” yellow catfish and yellow catfish in four fish ponds test. The test fish ponds were respectively given specifications of 3 ~ 5 cm / tail yellow catfish, “all male No. 1” and specifications of 3 ~ 5 cm / tail catfish. The results showed that the production performance of yellow catfish “All male 1” was better than that of yellow catfish, the feed conversion efficiency was higher than that of yellow catfish, the feed coefficient was 20% lower than that of yellow catfish, and that of yellow catfish Number of fish species per unit output reached 510 kg / 667m2, the unit profit reached 7093 yuan / 667m2; Catfish fish species per unit yield of 367.6 kg / 667m2, unit profit of 3069 yuan / 667m2.
