一、前言 海洋鱼类在不同的生活时期对海水温度的适应性是不同的。就是相同的鱼类,栖息于不同的海区,其对水温的适应性也是不同的,由于鱼类对海水温度的适应性最为敏感,当水温变化在0.1—0.2℃之间时,都会引起鱼类行动的变化。如小黄鱼(PseudosciaenaPolyactis Bleeker)在黄海越冬场时期适温范围为8.0—12.0℃,春汛生殖洄游停留在烟威渔场适温范围为5.0—6.5℃到达渤海莱洲湾产卵场时,进入渔场的温度为8.0℃以上,
I. INTRODUCTION The adaptability of marine fish to seawater temperature is different during different lifetimes. Is the same fish, habitat in different sea areas, their adaptability to the water temperature is also different, because the fish are most sensitive to the adaptability of seawater temperature, when the water temperature changes between 0.1-0.2 ℃, will cause the fish Changes in action. For example, when the Pseudosciaena polyactis Bleeker reaches 8.0-12.0 ℃ during the wintering period of the Yellow Sea, the reproductive migration in spring flood reaches a temperature of 5.0-6.5 ℃ in the farmyard, Is above 8.0 ° C,
