| 摘 要： | 斑点叉尾(鮰)(Ictalurus punctatus)苗种培育分为三个环节,对苗种培育池塘条件、生态环境因素、营养饵料及投喂方式、放养密度、饲养管理方式等进行了试验研究.结果表明,仔鱼流水池暂养适宜面积约为12m2、放养密度在10 000尾/m2以下,采用浮游动物与蛋白质含量40％的配合饵料相结合的方式进行投喂；夏花苗种培育适宜池塘面积1 400～2 533 m2,放养密度45.0尾/m2;大规格鱼种池塘培育的第一阶段适宜池塘面积约为3 333 m2,放养密度12.00～15.00尾/m2,投喂蛋白质含量36％～38％的配合饵料,第二阶段适宜池塘面积约为6 667 m2,放养密度6.00～6.75尾/m2,投喂蛋白质含量36％的配合饵料;大规格鱼种网箱培育第一阶段适宜网箱面积20～25 m2,放养密度1 000尾/m2,投喂蛋白质含量36％～38％的配合饵料；第二阶段网箱面积以30～33 m2为宜,放养密度500尾/m2,投喂蛋白质含量36％的配合饵料. |

| Abstract: | The key factors,including pool condition,ecological environmental condition,nurtitional diet,feeding,stocking density and management,were studied in three health nursing stages of channel catfish.For temporary culturing of catfish,the suitable flow pool area was 12 m2;stocking density was 10 000 ind./m2;and the proper feeding was zooplankton mixing commercial food with 40% proteins.For larval culturing,the suitable pool area was 1 400～2 533 m2,stocking density at 45.0 ind./m2.For first stage of large size fingerling pool culturing,the suitable pool area was 3 333 m2,stocking density at 12.00～15.00 ind./m2,and feeding commercial food with 36%～38% proteins.For second stage of large size fingerling pool culturing,the suitable pool area was 6 667 m2,stocking density at 6.00～6.75 ind./m2,and feeding commercial food with 36% proteins.For first stage of large size fingerling net cage culturing,the suitable area was 20～25 m2,stocking density at 1 000 ind./m2,and feeding commercial food with 36%~38% proteins.For second stage of large size fingerling net cage culturing,the suitable area was 30～33 m2,stocking density at 500 ind./m2,and feeding commercial food with 36% proteins. |
