钓鱼者了解气温、水温的变化吗?它会对钓鱼带来什么样的影响呢?

2017-05-13 08:04:07   

广大的钓鱼爱好者,经常会在钓鱼之前思考一个问题,今天的天气和气温适不适合钓鱼。下面我们就谈一谈这个问题。

鱼是属于变温动物,它的体温会随着水温的变化而变化,因此它们的生长繁殖需要有一个适宜的环境。鱼也会随着水温的变化而在不同的水层面活动。因此,水温与钓鱼就结下了不解之缘,钓鱼者只有了解了鱼在什么样的水温条件下吃食最勤,才可以满载而归。

但是钓鱼者怎样才能知道水的温度是多少呢?我们都知道气象部门是不报水温的,钓鱼的时候我们不可能带上温度计到钓点去测试。那么我们就必须要了解气温与水温的关系。一般来讲,知道了气温,也就知道了水温,这两者之间是互相联系,互相影响的。气温升高,水温也随之升高;气温降低,水温也随之降低。拿一天来计算,如果早晨6点,气温10度,则表层水温约12~15度;中午12时,气温20度,则表层水温约15~18度;下午2时,气温24度,则表层约18~22度;下午6时,气温16度,则表层约18~20度;子夜零时,气温下降到8度,则表层约12~18度。总之,水温的升降要略滞后于气温变化;而且,每天只有极短暂的二次时间,气温和表层水温是相同的。

按照钓鱼界和养殖业的说法,表层水温就是指水面至水下50厘米的水层。钓鱼者要知道表层水温就是指的水的平均温度。因为水传递冷热的速度比空气慢,水表和水底存在着温差,水越深,温差越大。夏日里最好在上下温差较小的水域钓鱼。需要钓鱼者注意的是冬日与夏日相反,钓鱼最好在水温上下差别较大的水域。如果上层水结冰(0度),底层水仅2~4度,鱼儿都跑到深而暖的水区去了,在上层是不进食的,是钓不到鱼的。如果表层水结冰(0度),底层水10~15度,则钓鱼是甚好的,鱼儿都皆食饵。如果再遇上鱼窝那就更好了。

最后要和热爱钓鱼的朋友们说的是,以上的内容都是钓鱼的老手在长期的垂钓中摸索出来的一些经验,只供大家参考,希望能从中帮到大家。
