摘要
本文从鱼种产量,经济效益,能量利用率,氮素利用率,鱼种的肉质等诸方面对主施沼液和主施鸡粪培育鱼种与套养蚌种进行比较研究。结果表明,主施沼液者佳,主施鸡粪者差。作者在试验过程中对肥饵和水质定期进行了测定,指出主施沼液培育鱼种是一条简单易行,成活率高,质量好,成本低,效益高的途径。
Fish and clams breeding with digested liquid sludge and thicken manure res- pectively in the aspects of production of fish fry, production and its economic efficiency, utilization rate of energy and nitrogen element and the meat quality of fish fries are compared and studied.The results show that digested liquid sludge is much better than chicken manure in the fish and clams breeding. Based on the regular analysis and determination of the quality of manure,bait and water in the experiment, it is suggested that breeding fish fry with digested liquid sludge is the simpler and better way for increasing fry survival rate, fish quality, and economic efficiency and for lowering investment cost,
