摘  要：
研究了体重、水温、盐度、pH、光周期和体色对丁(Tinca tinca)幼鱼耗氧率的影响。结果表明:在水温(20±0.5)℃下,丁[体重(126.9～151.6)g,体长(21.71～22.64)cm]的耗氧率有明显的昼夜节律性,一昼夜出现两个耗氧高峰,分别在6:00和18:00;耗氧率(Y)与体重(W)呈负相关,关系式为:Y=0.6807W-0.3034(r=-0.9983);耗氧量(Yˊ)与体重呈正相关,关系式为:Yˊ=0.6787W0.697(r=0.9995)。在(15～30)℃水温范围内,耗氧率(Y)随着水温(T)的上升而增大,关系式为:Y=0.106T0.4688(r=0.9943)。盐度升高(0～9),耗氧率先升高后降低。耗氧率随着pH值(6.0～9.0)的升高而降低。体色和光周期对丁耗氧率有显著的影响(P<0.05)。

摘  要：
The effects of weight,temperature,salinity,pH,body color and photoperiod on oxygen consumption rate were studied at(20±0.5)℃ in this paper,with juvenile tench Tinca tinca samples of(126.9~151.6)g body weight and(21.7~22.6)cm body length.The results showed that diurnal rhythm of the consumption was observed in the experiment,the two oxygen consumption peaks occurred at nearly 6:00 and 18:00.The oxygen consumption(Yˊ) increased with body weight(W) increasing,while the oxygen consumption rate(Y) decreased with the body weight increasing,the correlation formulas was Yˊ=0.6787W0.697(r=0.9995)and Y=0.6807W-0.3034(r=-0.9983).And the oxygen consumption and the oxygen consumption rate(Y) raised with the increase of water temperature(T) from 15℃to 30℃(the correlation formulas was Y=0.106T0.4688,r=0.9943)and decreased with the increase of pH from 6.0 to 9.0.When salinity changed from 0 to 9,the oxygen consumption rate raised in the beginning then decreased.And the oxygen consumption rate was effected by body color and photoperiod significantly(P<0.05).
