养鱼饲料中的动物性蛋白长期以来以进口鱼粉为主。进口鱼粉不仅价格高,耗费大量外汇,而且还很难买到,严重地阻碍了鱼类养殖业的发展。为了充分开发和利用本地饲料资源,我们用湖北地区盛产的经济价值不高的小米虾和虾壳粉。代替鱼粉进行了鲤鱼的养殖试验,其效果良好。现报道如下:材料与方法首先设计出鲤鱼饵料配方,然后根据配方按比例称取、粉碎,再制成φ1—2毫米的颗粒。试验在丹江口水库风凰山库湾网箱中进行,网箱规格为4×7×2米,网目2.5公
Animal protein in fish feed has long been dominated by imported fishmeal. Imported fishmeal is not only expensive, consumes a lot of foreign exchange, but also difficult to buy, seriously hindered the development of fish farming. In order to fully exploit and utilize local feed resources, we use the millet shrimp and shrimp shell flour, which are rich in economic value in Hubei Province. Instead of fishmeal carp breeding test, the effect is good. Are reported as follows: Materials and methods first designed carp bait formula, and then according to the formula weighed, crushed, and then made φ1-2 mm particles. The test was carried out in the Fenghuangshan Bay Cage of Danjiangkou Reservoir with a cage size of 4 × 7 × 2 m and a mesh of 2.5 km
