鳜和乌鳢最适温度的研究

THE OPTIMUM TEMPERATURES FOR THE MANDARIN FISH(SINIPERCA CHUATSI)AND THE NORTHERN SNAKEHEAD(CHANNA ARGUS)

  • 摘要: 研究了体重47.2-40.2g的鳜和4.0-46.2g的乌鳢的最适摄食和生长温度.结果表明,鳜的最大摄食率随温度的上升而增大,在2-3℃之间形成"最适温度平台";低温(10-2℃)时,乌鳢的最大摄食率随温度的上升而增加,在2-30℃之间形成"最适温度平台",之后随温度的增加而下降;鳜的特定生长率随温度的增加而加快,在2-3℃形成"最适温度平台";乌鳢的特定生长率受体重和温度的交互影响 .

     

    Abstract: Studies on the optimum temperatures for food consumption and growth in the mandarin fish Siniperca chuatsi)Basilewsky) weighing 47.2-540.2g and the northern snakehead weighing 47.2-540.2g and the northern snakehead Channa argus)Cantor)weighing 45 0-546 2g were conducted in the laboratory. The maximum rate of food consumption in the mandarin fish increased with increasing temperature, and an "optimum temperature platform" was formed between 25-35℃. At lower temperatures)10-25℃), the maximum rate of food consumption in the northern snakehead increased with increasing temperature and an "optimum temperature platform" was formed between 25-30℃. A further increase in temperature led to decreased rates of food consumption. The specific growth rate in the mandarin fish increased with increasing temperature, and an "optimum temperature platform" was formed between 25-35℃. The specific growth rate in the northern snakehead was interacted both by body weight and temperature. weighing 45 0-546 2g were conducted in the laboratory.
