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℃。
The results show that: (1) The fish have a certain choice of water temperature. With the change of water temperature, the temperature of fish keeps the same directional change as the change of water temperature. The choice of warm water species is more biased toward the higher temperature than warm species. If the water temperature rises quickly or the water temperature originally adapted to the fish species is lower, the temperature of the fish species will be biased towards the low temperature direction. ② The water temperature selected by the main catch of the lamp around the sea in different months is 1 ~ 3 ℃ higher than the middle of the month’s water temperature, most of them are concentrated in the high 1 ~ 2 ℃. ③ The temperature of the main fishing targets in winter and spring is 20 ~ 24 ℃, while the selected water temperature in summer and autumn is 26 ~ 29 ℃. The main species of fish in different months of choice temperature range of 2 ~ 6 ℃, most of 3 ~ 5 ℃.
