| 摘要: |
| 在实验室内测定30尾斑点叉尾鮰鱼苗的群体耗氧率和窒息点。鱼苗平均体长2.11cm,平均体重0.10 g。试验用水为曝气24 h以上的自来水,水的碱度2.60 mg N/L,硬度1.15mg N/L,pH值7.2,溶氧5.86mg/L。结果表明,在水温28.2℃~28.5℃时的斑点叉尾鮰鱼苗的耗氧率为0.5233mg/g·h,耗氧量为0.0544毫克/尾·小时,窒息点为0.5226mg/L。斑点叉尾鮰的耗氧率呈现出明显的昼夜变化。 |

| Abstract: |
| Thirty fishes of Ictalurus punctatus with 2.11 cm long and 0.10 g weight on average were tested. The tap water before used was treated with oxygen for 24 hours or above. The hardness of water is 1.15 mgN/L, pH 7.2, alkalinity 2.60 mgN/L, dissolved oxygen 5.86 mg/L. At 28.2℃~28.5℃ of water temperature,the oxygen consumption rate of I. punctatus is 0.5233 mg/g· h;the amount of oxygen consumption is 0.0544 mg/individual·h, and the stifle point is 0.5226 mg/L. The oxygen consumption rate has a obvious fluctuation of day and night. |
