摘要: 采用Winkler法研究了温度、盐度、pH和麻醉剂对长鳍篮子鱼幼鱼(体长(3.325±0.205) cm,体质量(0.706±0.155) g)耗氧率的影响。结果表明:长鳍篮子鱼幼鱼耗氧率随着温度升高而增加,其回归关系可用对数函数 Y =1.3819ln X -3.55( r =0.9475, P <0.01)表示,其生长的适宜温度为24 ℃~32 ℃;幼鱼耗氧率随着盐度的降低而逐渐增加,其回归关系可用线性函数 Y =-0.1802 X +1.7551( r =0.9837, P <0.01)来表示;在不同的pH下耗氧率有显著性差异( P <0.01),pH值在6.0时耗氧率最低,9.0时耗氧率最高;耗氧率随着丁香酚、MS-222的浓度升高而逐渐降低,各实验组的耗氧率要显著低于对照组,丁香酚和MS-222可以作为长鳍篮子鱼幼鱼运输过程中的麻醉剂。

Abstract: By using Winkler′s method, this paper studied the variation patterns of the oxygen consumption rate of juvenile Siganus canaliculatus  (body mass (0.706±0.155) g, body length (3.325±0.205) cm) under effects of different water temperature, salinity, pH, and anaesthetics. The oxygen consumption rate of juvenile S. canaliculatus  was increased with the increase of water temperature and the decrease of water salinity, and the regressive correlations could be represented by logarithmic equation Y = 1.3819 ln X -3.55 ( r =0.9475,  P <0.01) and linear equation Y =-0.1802 X +1.7551  (r =0.9837,  P <0.01), respectively. The optimum temperature for the juvenile′s growth was from 24 ℃ to 32 ℃. Water pH also had significant effects (P<0.01) on the oxygen consumption rate which was the lowest at pH 6.0 and the highest at pH 9.0. The oxygen consumption rate decreased with increasing concentration of eugenol and MS-222, and was significantly lower in experimental groups than in control group. Eugenol and MS-222 could be used as the anaesthetics for the long distance transportation of juvenile  S. canaliculatus .
