摘 要：
研究结果表明 :①鱼类对水温具有一定的选择范围 ,随水温的变化 ,鱼类对温度的选择保持与水温变化方向相同的定向变化。暖水种的选择温度比暖温种更偏向高温方向。如果水温上升较快或鱼种原来所适应的水温较低 ,鱼种对温度的选择就会偏向低温方向。②本海域灯围主要捕捞对象在不同月份所选择的水温 ,大多数比该月水温的中间值高 1～ 3℃ ,较多集中在偏高 1～ 2℃。③主要捕捞对象在冬、春季的选择水温为 2 0～ 2 4℃ ,在夏、秋季的选择水温则为 2 6～ 2 9℃。主要鱼种在不同月份中的选择温度变化幅度为 2～ 6℃ ,多数为 3～ 5℃。

摘 要：
There is some selective water temperature range in fishes.Fishes keep up the same direction with water temperature variety in temperature selection.The seletive temperature of warm species tends to higher temperature than that of temperate species.If temperature goes up faster or temparature of fish adapted was lower,selective temperature of these fishes tend to lower.Seletive temperature of main species fished is 1-3℃ higher than the median temperature of that month, 1-2℃ higher in the majority of species.Variable range of selective temperature in main species is mainly 2-6℃,3-5℃ .Selective temperature in main species fished is 20-24℃ in winter and spring, 26-29℃ in summer and autumn.
