美国的斑点叉尾鮰池塘养殖素以单养为主,近年来做过一些混养试验,并证明混养可以提高鱼塘总产量。奥本大学科研人员发现,斑点叉尾鮰池塘单养每公顷可放养4400尾而收获量为1400公斤。当每公顷混加1240尾罗非鱼于池中,则每公顷可收获斑点叉尾鮰1568公斤、罗非鱼266公斤,使总产量达到每公顷1834公斤,比单养增产27.3%。这种鱼与罗非鱼混养时可以不增加或少增加投饵量,这是因为这两种鱼不争食,可以摄食藻类和饵料残渣,两者混养不但不影响斑点叉尾鮰的生长,还可
In the United States, Channel catfish pond aquaculture is dominated by monoculture. In recent years, it has done some polyculture experiments and proved that polyculture can increase the total output of fish ponds. Auburn University researchers found that the Picotus tabanulate pond monotrophs per hectare can be stocked 4400 and harvest 1400 kg. When 1240 tilapia were mixed in the pool per hectare, 1,568 kilograms of catfish and 266 kilograms of tilapia were harvested per hectare, bringing the total output to 1834 kilograms per hectare, an increase of 27.3% over monoculture. This fish with tilapia polyculture can not increase or increase the amount of feeding, it is because these two kinds of fish do not fight, you can take algae and bait residue, both polyculture not only does not affect the growth of Channel Catfish, but also
