精养鱼池的增产措施,重点依赖于饵料的投入,相应地提高了饲养成本,同时受池塘内淡水溶氧量的制约,鱼苗的投放密度受到限制,饵料的有效利用率也随之下降,因此影响产量的提高。 采用立体养殖技术,将投放饵料的一部分(约占三分之一)喂猪,通过猪排泄的粪便,投入沼气发酵 Intensified fish pond stimulation measures, relying mainly on the input of bait, raising the cost of feeding accordingly, while limited by the amount of fresh water dissolved oxygen in the pond, the feeding density of fry is limited, the effective utilization of food also will be reduced, Thus affecting the yield increase. The use of three-dimensional culture technology, part of the food will be fed (about one-third) pigs, excretion of pig excrement, into biogas fermentation
