摘要:

以鳜（Siniperca chuatsi）、瓦氏黄颡鱼（Pelteobagrus vachelli）、鲫（Carassius auratus）、鳙（Aristichthys nobilis）等四种暖水性鱼类为研究对象，分别在（28±1）℃和（10±1）℃条件下测定它们的临界游泳速度，采用SPSS17.0统计软件进行数据的分析比较。通过比较体长相近的鱼类，鳜的绝对临界游速和相对临界游速均显著性低于鳙（P＜0.01），瓦氏黄颡鱼的绝对临界游速和相对临界游速均显著性低于鲫（P＜0.01）。通过比较两种温度条件下同种鱼的临界游泳速度，结果发现四种鱼在这两种温度条件下的临界游速均有极显著性差异（P＜0.01），在（28±1）℃条件下四种鱼的临界游泳速度极显著性高于（10±1）℃条件下它们的临界游泳速度。

Abstract:

The critical swimming speed was measured in mandarin fish (Siniperca chuatsi), darkbarbel catfish (Pelteobagrus vachelli), crucian carp (Carassius auratus) and bighead carp (Aristichthys nobilis) at 28±1℃ and 10±1℃. The experiment was conducted in the annular flume (Fig 1). It mainly consists of two parts: power part and swimming area. The relationship between flow velocity in the tank and the impeller speed was showed in Fig 2 and the flow velocity could be adjusted by controlling the impeller speed. SPSS 17.0 software was used for data processing. Duncan’s multiple comparison procedure was used to compare the means of different groups. Comparing with the swimming performance among the species with similar length, it was discovered that the absolute critical swimming speed and relatively critical swimming speed of mandarin fish was significantly lower than bighead carp while the absolute critical swimming speed and relatively critical swimming speed of darkbarbel catfish was significantly lower than crucian carp (Table 1). A comparison of the critical swimming speed between two acclimation temperatures (Fig 3), the results showed that the temperature had extremely significant impacts on swimming performance. The critical swimming speed of fish at normal temperature was significantly higher than that at low temperature.
