池塘集约化养殖加州鲈的试验

Study on Rearing Large Mouth Bass in Pond

在合肥地区，平均尾重３８ｇ的加州鲈鱼种，以每公顷放养１０１７０的密度，并投喂适口的活饵料，年底可育成平均尾重４２６ｇ的商品鱼，养殖成活率可达８２．６％，产量单产３５７９ｋｇ／ｈｍ２。

The young Large-mouth basses that average bady weight was 38g were reared in pond in the early of year in Hefei.The rearing density was 10170 fish per hm 2 .The palatable live feedstuff fishes were fed at unfixed date.By the end of the year ,its average bady weight had met the denmand of commerical size (about 426g/per fish).The rate of survival was about 82.6%.The yield of commercial large mouth bass was 3 579kg/hm 2。
