近年来,名特优水产品养殖因经济效益高而正在吸引着越来越多的从业者。河蟹因味道鲜美、营养丰富、外销量大,而成为名特优水产品养殖的重要品种之一。但是,据笔者调查,目前有相当一部分河蟹养殖者的经济效益低下,究其原因有很多,我们认为主要是大多数养殖者在投喂饲料方面常常是有啥喂啥,不能全面地满足河蟹营养需要,形成河蟹营养缺乏、蜕壳困难、生长缓慢、抗病力弱、发病率高等现象。有鉴于此,浙江省绍兴农垦饲料厂利用中国水产科学研究院淡水渔业研究中心的技术,生产出了818河蟹全价颗粒饲料。本文就该种饲料在实际生产中的饲喂情况作一总结。

Crab because of the delicious taste, nutrient-rich, large volume of export, and become famous Teyou aquaculture one of the important species.
