摘要
以水库上、下层水体作养鳗水源,利用大坝内外水位落差,通过虹吸管自动灌水,使鳗池池水保持微流。试验水泥池4只共1.32亩,计放养鳗苗37983尾共280公斤,经198天饲养,收获成鳗915.5公斤,幼鳗1275.6公斤。成活率95.14％,饵料系数1.86。
Eels were cultured in four concrete tanks with microflowing water, which was si-
phoned from the upper and lower layers of the reservoir,in an area of 1. 32mu. 37983 elvers about
280kg were stocked in total. After 198 days,915. 5kg of adult and 1275. 6kg of young eels were har-
vested,with an survival rate of 95. 14 % and an food coefficiont of 1. 86
