| 运用封闭流水式实验方法研究温度、盐度、pH和流速对卵形鲳鲹(Trachinotus ovatus)幼鱼耗氧率和排氨率的影响。实验结果表明,随着温度的升高,耗氧率和排氨率均是先增大后减小,当温度为27℃时,耗氧率和排氨率达最大值,温度对卵形鲳鲹幼鱼耗氧率和排氨率的影响显著(P<0.01);耗氧率和排氨率随着盐度的升高均出现降低的趋势,盐度对耗氧率和排氨率的影响均显著(P<0.01);随着pH的升高,耗氧率的变化不明显(P>0.05),排氨率呈先增大后减小的趋势,pH对卵形鲳鲹幼鱼排氨率的影响显著(P<0.05);随着流速的增大,耗氧率和排氨率先增大后减小,在流速为150 ml/min时达最大值,流速对卵形鲳鲹幼鱼耗氧率和排氨率的影响均达显著水平(P<0.01)。 |
| 英文摘要: |
| The effects of temperature, salinity, pH and water velocities on oxygen consumption and ammonia excretion of Trachinotus ovatus were determined by the closed flow experimental methods. The results showed that the oxygen consumption and ammonia excretion of juvenile T.[KG-*9]ovatus would be increasing as water temperature increasing, and the volumes reached to a peak value at 27℃. Water temperature had significant effects on oxygen consumption and ammonia excretion (P<0.01).The oxygen consumption and ammonia excretion of juvenile T.ovatus decreased as the salinity increasing, and salinity also had significant effects on the oxygen consumption and ammonia excretion (P<0.01). As the pH increases, the oxygen consumption did not change significantly (P>0.05). The value of pH had a significant effect on the ammonia excretion (P<0.05), the ammonia excretion was increased first, then decreased with pH increasing. Oxygen consumption and ammonia excretion of juvenile T.ovatus increased gradually as water velocity increasing and reached to peak values at 150 ml/min, then decreased gradually as water velocity over 150 ml/min. The effects of water velocities on oxygen consumption and ammonia excretion in juvenile T.ovatus were significant (P<0.01). |
