1、鱼的洄游主要有四种:生殖洄游、索饵洄游、趋暖洄游、越冬洄游。

2、Alsobecomeextremelywary.

3、鱼在不同季节有不同的活动范围,就是在一天里它有活动地点也在不时变更,这里面有食物、水温变化带来的影响,同时人为干扰也不容忽视,因为有些人水域钓鱼人多、旅游的人也多,鱼在此环境生存,抗钓本能增强。

11、洄游是一种现象,鱼类正是凭借这种活动满足它在某个生活时期需要的外部条件,使它的种群繁衍得到可靠的保证。

12、Migrationisonekindofphenomenon,fishispreciselyreliesonthiskindofactivityinsomelifeperiodtomeetitsneedsexternalconditions,makeitspopulationmultiplygetreliableguarantee.

13、总之,鱼类在生命活动中有一种同期性、定向性和群体性的迁徙活动习性,我们把这种现象称之为洄游。

19、鱼在觅食时受天气影响也是比较大,天气闷热、气压低,鱼就会出现厌食现象,较大的鱼就会躲在水里不吃不动;

20、Thesummeraftertherainwatergaragecarpwillupriverstoupstreamnearforaginginlet;

21、鱼在水下四处游动,其主要目的就是觅食,因为这是它们赖以生存的唯一手段,鱼又是变温动物,它的体温随着水温变化而变化,所以说不同季节的水温变化都很大程度上限制了鱼的活动范围。

22、同时也变得异常警觉。

24、夏季雨后水库里的鲤鱼会溯流到上游进水口附近觅食;

27、反之,水温过低,鱼的代射功能减缓,它也会拒食,当水温适宜、溶氧充足,特别是夏季雨后,鱼儿就会活动异常,觅食积极主动,咬钩率成倍提高,当有的地方有食物时,鱼儿就会通过特有的方式互传信息,趋之若骛前去觅食,而水库一旦放水,水位迅速下降,鱼儿就会表现的惊恐不已,躲在较深的水里很少进食,这些也是鱼的习性特点。

28、我们在钓鱼中经常发现,春天鲤鱼、鲫鱼、鲇鱼等鱼种从深水来到浅水交尾;
