本实验采用静水封闭呼吸室法,研究了pH (5、6、7、8、9、10)、盐度(0、2、4、6、8、10)对禾花鲤耗氧率、窒息点的影响,并且建立了pH、盐度与耗氧率、窒息点的回归方程模型。实验结果表明:pH、盐度(S)对禾花鲤幼鱼耗氧率和窒息点有显著影响(P < 0.05)。当pH、盐度分别为7.3、1.55时,窒息点(DAP)最低,回归方程为DAP = 0.0248pH2 − 0.3558pH + 1.6129 (R2 = 0.929)、DAP = −0.0012S3 + 0.025S2 − 0.0668S + 0.4644 (R2 = 0.9958);当pH、盐度分别为6.0、2.0时,耗氧率(R0)最低,回归方程为:R0 = −0.003pH3 + 0.0723pH2 − 0.548pH + 1.6602 (R2 = 0.9602)、R0 = −0.0001S3+ 0.002S2 − 0.0022S + 0.3037 (R2 = 0.965)。当溶氧不充足时,pH、盐度分别为7.3、1.55的环境条件下,有助于提高禾花鲤耐低氧能力。 In this experiment, the static water closed breathing chamber method was used to study the pH (5, 6, 7, 8, 9, 10) and salinity (0, 2, 4, 6, 8, 10) on the oxygen consumption rate and asphyxiation point of Procypris merus
. The regression equation model of pH, salinity and oxygen consumption rate, and suffocation point was established. The experimental results showed that pH and salinity (S) had significant effects on the oxygen consumption rate and asphyxiation point of juveniles of
Procypris merus
(P < 0.05). When the pH and salinity were 7.3 and 1.55, respectively, the asphyxiation point (DAP) was the lowest. The regression equations were
DAP
= 0.0248pH2 − 0.3558pH + 1.6129 (R2 = 0.929), and DAP = −0.0012S3 + 0.025S2 − 0.0668S + 0.4644 (R2 = 0.9958); when the pH and salinity are 6.0 and 2.0 respectively, the oxygen consumption rate (R0) is the lowest, and the regression equations were: R0= −0.003pH3 + 0.0723pH2 − 0.548pH + 1.6602 (R2 = 0.9602), and R0 = −0.0001S3+ 0.002S2 − 0.0022S + 0.3037 (R2 = 0.965). When dissolved oxygen was insufficient, the hypoxia tolerance of the
Procypris merus
was improved under the environmental conditions of pH 7.3 and salinity 1.55, respectively.
