摘要
选用8种饲料——鱿鱼、环棱螺、舌鳎、鲫鱼、海虾、螯虾、硬颗粒及软颗粒饲料,对花鲈(Lateolabraxjaponicus)鱼种进行饲养试验,比较不同饲料的生长效果。结果表明,花鲈鱼种的日增重率与所摄取食物的干重占体重的百分比呈直线正相关;8种饲料以软颗粒饲料的饲料系数最低,为0.88,其能量利用效率最高,达31.31%。
Eight sorts of typical feed commonly used in aquaculture, i.e. squid, river shells , tonguefish, crucian carp, sea shrimp , crayfish, pellet and soft pellet were chosen to separately feed fingerlings of sea bass ( Lateolabrax japonicus ) in the experiment, and the utilization rates of different feed were compared. The results showed that there was straight positive correlation between the daily growth rate in fish weight and the percentage of the dry weight of feed taken by fish to its body weight. Feed coefficient of soft pellet was the least, only 0.88 and its energy utilization rate reached 31.31%, being the best.
