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)。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 （Y ＇ ） increased with body weight （W） increasing, while the oxygen consumption rate （Y） decreased with the body weight increasing, the correlation formulas was Y ＇ = 0. 6787 W 697 （ r = 0. 9995 ） and Y = 0. 6807 IV- 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. 106T4688, 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 ）.
