趋暖避寒是动物在冬季的本能反应,鱼类也不例外。海洋中鱼类的趋暖避寒行为体现出季节性洄游的特点。淡水鱼在冬季的活动受水温的制约,它们会在水域中的高温区或高温层觅食栖息或冬眠。水温是冬钓的最重要的参考因素,撇开竿、钩、线、漂、坠、饵等使用因素,冬钓应依水温“四定”: 一、选择高水温时间从而确定 Warming cold is the instinct of animals in winter, fish is no exception. The warm and cold behavior of fish in the ocean reflects the characteristics of seasonal migration. The activity of freshwater fish in the winter is restricted by the temperature of the water, which will seek habitat or hibernation in the hot or hot areas of the water. Water temperature is the most important winter fishing reference factor, aside from the use of rods, hooks, lines, floats, fall, bait and other factors, winter fishing should be based on water temperature “four fixed”: First, select the high water temperature to determine the time
