摘要:用“升索牌”牙鲆专用饵料作为残饵、以静水法培养法研究了氨氮在水-残饵界面的迁移速度.结果表明,在5,10,20和30 ℃时的迁移速度分别是0.289 8±0.057 2,R=-0.01 6±0.000 4t+0.285 5±0.030 2,0.269 1±0.149 0和0.241 5±0.080 5μmol·g-1·h-1.该残饵的鱼当量为0.04~0.54尾牙鲆.即对于牙鲆而言,如果投喂的饵料为“升索牌”饲料,那么残饵使养殖容量降低的比率为0.04~0.54(m/(cc)-α),平均为0.23±0.14(m/(cc)-α).

Abstract: The transportation speed of ammonia across the water-feed-remains interface was determined by one static water system,during which the feedstuff with the trademark Shengsuo was used as the feed-remains.At 5,10,20,30 ℃,the speed was 0.289 8±0.057 2,R=-0.01 6±0.000 4t+0.285 5±0.030 2,0.269 1±0.149 0,0.241 5±0.080 5μmol·g-1·h-1,respectively.And the fish equivalent of this kind of feedstuff was 0.04~0.54 inds/g.From the point of the ammonia excretion of P.olivaceus Temminck et Schlegel,if the cultivated P.olivaceus Temminck et Schlegel is fed by the feedstuff with the trademark Shengsuo,the mean reduction ratio of holding capacity which caused by the feed-remains is 0.23±0.14(m/(cc)-α) and the range is 0.04~0.54(m/(cc)-α).

Key words: feed-remains, nutrients, water temperature, transportation speed, fish equivalent
