摘要
为调整水产养殖品种结构,提质增效,濮阳县引进罗非鱼进行养殖,采用搭建温室大棚,利用地热井调节池塘水温,通过水质调控、高效增氧和加强病害防治等措施,165 d左右把罗非鱼大规格鱼种养殖成商品鱼,饲料系数1.26,取得良好的经济效益。
In order to adjust the structure of aquaculture species,improve quality and increase efficiency,tilapia was introduced in Puyang county.Greenhouses have been built and geothermal wells have been used to regulate the temperature of pond water,and breeding is carried out through measures such as water quality regulation,efficient aeration,and enhanced disease control.For about 165 days,large-sized fingerlings were bred into commercial fish with a feed coefficient of 1.26,which achieved good economic benefits.
