摘  要：
在湖南省岳阳洞庭黄龙水产养殖股份有限公司生态养殖基地的鱼池中,分别投喂桂牧1号草、美国矮象草、苎麻3种饲草,研究草鱼主养池塘中鱼类的生长及效益。150 d的养殖试验结果表明:桂牧1号草组的草鱼增重率、特定增长率均显著高于美国矮象草组、苎麻组(P<0.05),其中苎麻组的草鱼增重率、特定增长率又显著高于美国矮象草组(P<0.05);各试验组中,鲢鱼和青鱼的增重率、特定增长率差异均无统计学意义(P>0.05),但美国矮象草组中的鳙鱼增重率、特定增长率显著高于其他2组(P<0.05);桂牧1号草组鲢鱼成活率显著高于美国矮象草组、苎麻组(P<0.05),其中苎麻组又显著高于美国矮象草组(P<0.05),各试验组中的草鱼、鳙鱼、青鱼成活率差异均无统计学意义(P>0.05);投喂桂牧1号池塘中的鱼类总产量及效益最高,分别为934.25 g/m2、26 967.75元/hm2。综合分析,投喂桂牧1号池塘中的鱼类生长良好,且养殖效益最高。

摘  要：
A 150-day feeding trail was conducted in land-based fish ponds in the experimental base in Dongting Huanglong Company,Yueyang,Hunan to compare fish yield and economic efficiency in ponds mainly culturing grass carp fed with grass cultivar Guimu No.1,dwarf elephant grass and ramie,respectively.The results showed that the growth rate(GR),specific growth rate(SGR) of grass carp feeding Guimu No.1 were significantly higher than those of grass fish feeding dwarf elephant grass or ramie(P <0.05),and the GR,SGR of grass carp feeding ramie were significantly higher than these of grass fish feeding dwarf elephant grass(P <0.05).The GR,SGR of silver carp and black carp showed no significant difference in all test ponds(P >0.05),but GR,SGR of bighead carp in ponds fed with dwarf elephant grass were higher than those fed with the other two grasses(P <0.05).The survival of silver carp in pond fed with Guimu No.1 was significantly higher than other ponds(P <0.05),but survival of grass carp,bighead carp and black carp showed no significant difference in all ponds(P >0.05).The pond fed with Guimu No.1 had the highest fish yield and economic benefits,which were 934.25 g/m2,26 967.75 yuan/hm2 respectively.The results above showed that grass carp pond fed with Guimu No.1 had the highest economic benefits with fishes growing well.
