摘 要:介绍了云南省曲靖市沿江乡种草养鱼的经验。该乡渔业生产比重仅次于粮食生产而居第二位,过去以酒糟等精饲料养鱼,成本高,效益低,鲜鱼产量仅有2055kg/hm2;现在采取种草养鱼,扩大了饲料来源,降低了饲养成本,提高了产量和效益,鲜鱼产量达到了3835.3kg/hm2,比过去提高了86.63%。这一措施为当地经济生产开辟了一条新途径。he experence of growing herbage and fish culture in Yanjiang Township of Qujing City,YunnanProvince was introduced.Fishery proportion of the township was the second only to cereal production.
