3种膨化颗粒饲料养殖黄颡鱼效果对比试验

Comparison of Three Extruded Pellets Feeding on Yellow Catfish

在相同养殖模式和管理措施前提下,进行膨化饲料饲养黄颡鱼试验,结果表明,含粗蛋白30%、41%和42%的3种膨化饲料饲料系数分别为2.23、1.48、1.50;从经济性、生物学评价体系进行比较,含粗蛋白41%和42%的膨化饲料适合于黄颡鱼的养殖。

Under the same culture model and management measure,three extruded pellet-feeding on catfish were tested. The experimental results showed that for the three extruded pellets with 30%,41% and 42% crude protein, the feed coefficients were 2.23,1.48 and 1.50 respectively. According to the economical and biological evaluate system the latter two extruded pellets are suitable for Pelteobagrus fulvidraco farming.
