为提高精养斑点叉尾(鱼回)的经济效益,美国俄克拉何马州立大学水产研究站在精养斑点叉尾(鱼回)(400尾/m~3)的水泥池中混养罗非鱼25、50、75尾/m~3与单养斑点叉尾(鱼回)进行比较试验.放养的斑点叉尾(鱼回)的平均体重为1.93g,混养的奥利亚罗非鱼的平均体重为35.9g.6~10月水温19.85~29.25℃,溶氧4.14~6.95mg/l.试验140d发现:在混养不同数量罗非鱼的池中,斑点叉尾(鱼回)的体长(264~333mm)和体重(174.2~456.6g)
In order to improve the economic benefits of intensive channel catfish (fish back), Oklahoma State University Aquatic Research Station mixed culture in a pool of intensive channel catfish (400 fish / m ~ 3) The non-fish 25,50,75 tails / m ~ 3 were compared with the single feeding channel catfish (fish back) .The average weight of broodstock (fish back) stocked was 1.93g, The average body weight of fish was 35.9g.6 ~ October water temperature 19.85 ~ 29.25 ℃, dissolved oxygen 4.14 ~ 6.95mg / l .Test 140d found: in the polyculture of different numbers of tilapia pool, channel catfish (fish back) Of body length (264 ~ 333mm) and weight (174.2 ~ 456.6g)
