鲢鳙鱼由于季节和气温的变化,它们在水中生活的深度也有相应变化。在夏秋时节的一天当中,早晨一般游弋在距水面1米左右的深度上,中午阳光强时,会下到1~3米深处,下午太阳西下后,它们又上升到水面。故许多钓鱼人常看到这样的景象:早晚看见鲢鳙在水面卷起一个个浪花,中午却风平浪静,就是因为它们有以上生活规律所致。
Silver carp and bighead carp due to seasonal and temperature changes, their depth of life in the water also have a corresponding change. During the summer and fall of the day, the morning is generally cruising at a depth of about 1 meter from the surface of the water. When the sun is strong at noon, it will go down to 1 to 3 meters deep. After the sun goes west in the afternoon, they rise again to the surface of the water. So many anglers often see such a scene: sooner or later saw silver carp and bigheads roll up a wave of water on the water, but calm at noon, it is because they have the above rules of life.
