用配合饲料Ⅰ ,Ⅱ和白鲢肉、泥鳅肉、猪肉、田螺肉等 ,在室内饲养黄颡鱼 6 0天。结果表明 ,6种饵料在黄颡鱼消化道中出现率、鱼体重增加率和胃、肠蛋白酶与淀粉酶活性均以配合饲料Ⅰ最高 ,白鲢肉次之 ,表明黄颡鱼具有较强的消化能力。在水温 2 1℃时 ,黄颡鱼耗氧率为 1 4 4mg/h·kg,比养殖前增高了 1 3.8% ,窒息点为 0 .30 9mg/L ,与养殖前的差异不显著。因此 ,黄颡鱼可进行人工养殖
With compound feed Ⅰ, Ⅱ and silver carp, loach meat, pork, snail meat, etc. Cattle indoors 60 days. The results showed that the incidence of six kinds of bait in the digestive tract of yellow catfish, fish weight gain and stomach, intestinal protease and amylase activity were highest with feed Ⅰ, followed by silver carp, indicating that catfish with strong digestion ability. At the temperature of 21 ℃, the oxygen consumption rate of yellow catfish was 114.4mg / h · kg, an increase of 1.38% compared with that before breeding, and the point of suffocation was 0.309mg / L, which was not significantly different from that before breeding. Therefore, yellow catfish can be cultured
