长期以来,花白鲢在我国滤食性网箱鱼类中堪称“主角”,虽有成本低,投入少的优势,但产值效益难以提高。随着我国市场的开发,鲢鱼已不能满足大众口味,百姓菜篮子对鱼食品的种类要求越来越高,一些质量较高的品种越来越受到欢迎。近年来,水库渔业所科研人员在清江隔河岩水库成功利用不投饵滤食性网箱养殖的匙吻鲟,就是从美国引进的一个高档品种,经5个月驯养,当年苗种成活率达到100%,每平方米单产3.23公斤,平均每尾达到2.5公斤,获利润4424元,平均每养殖一尾匙吻鲟创利润130.12元。它的成功移植,为优化我国滤食性网箱品种开辟了一个崭新的天地。滤食性网箱养殖是一种对水环境影响较小的环保型养殖方式,而不投饵网箱养殖匙 For a long time, silver carp in China’s filter-feeding cage fish called “protagonist”, although the cost is low, the advantages of less investment, but the output value of the benefit is difficult to increase. With the development of the market in our country, the silver carp can no longer meet the public tastes. People’s baskets demand higher and higher types of fish food, and some higher quality varieties are more and more welcomed. In recent years, researchers at Reservoir Fisheries successfully used paddy sturgeon cultured in the Geheyan reservoir in Qingjiang River to feed the cage without feeding the filter cage, which is a high-grade variety introduced from the United States. After five months of domestication, the survival rate of the seedlings reached 100% , Yielding 3.23 kilograms per square meter, an average of 2.5 kilograms per tail, a profit of 4424 yuan, an average of each breeding a spoonfish sturgeon a profit of 130.12 yuan. Its successful transplantation has opened up a brand new world for the optimization of filter cage species in China. Cage feeding cage culture is a less impact on the water environment, environmentally friendly farming methods, rather than feeding the cage culture spoon
