本文测定了倒刺鲃鱼种的临界水温和溶氧量。倒刺可生存的水温范围约是4℃～37℃,开始致死的临界上、下限水温分别为3℃和38℃;鱼开始浮头和窒息时的水溶氧量分别为1.84mg/1和0.96mg/1。并对有关问题进行了初步的比较探讨。
In this paper, the critical water temperature and dissolved oxygen of barbed catfish species were determined. Barb survive the water temperature range is about 4 ℃ ~ 37 ℃, start lethal threshold, the lower limit of the water temperature were 3 ℃ and 38 ℃; fish began floating head and asphyxia of water-soluble oxygen were 1.84mg / 1 and 0.96mg /1. And carried on the preliminary comparison discussion to the related question.
