| 摘 要： | 研究了低pH(6.0—3.6)对草鱼呼吸活动机能及耗氧代谢的影响.结果表明,在pH4.6—3.6条件下,草鱼呼吸和气体代谢活动受干扰的程度随酸度增大而急剧加重.其具体表现为:呼吸率加快,咳嗽反应增加,呼吸深度加大.耗氧率起始升高继而迅速下降,并在极端pH(3.6)下最终引起机体组织缺氧而致死.对于pH5.6,草鱼各类呼吸与代谢指标未受明显影响,基本属于正常.供试草鱼对低pH反应的灵敏程度依次为:咳嗽率>呼吸率>耗氧率>呼吸深度.

| Abstract: | The results of the effects of low pH (6.0-3.6) on grass carp indicated that the respiratory activity and oxygen consumption metabolism at pH 4.6-3.6 was disturbed at higher degree to increscent acidity. The symptoms were increase in ventilation rate, cough rate and depth of breathing, and sharp decrease in oxygen consumption rate after an increase at the beginning. The sensitivities of grass carp to
low pH Were Orderly: cough rate>vcntilation rate>oxygen consumption rate>depth of breathing. These symptoms disappeared at pII 5.6. |
