关于介绍鱼类生活习性的英文章,
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.
Fish in underwater roam, its main purpose is foraging, because this is the only way they can survive, fish is variable temperature animals, its temperature changes with temperature, so the water temperature changes in different seasons are largely limits the fish's activities.
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.
Fish in different seasons have different range of activities during the day it is from a venue change in, there is food and water temperature change effects, and human interference also nots allow to ignore, because some people waters travel more than angler, in this, fish environment to survive, resistance to strengthen. Fishing instinct
同时也变得异常警觉.
Also become extremely wary.
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；
Fish when the foraging protected from the weather is bigger, the humid weather, low air pressure, fish will appear anorexia phenomenon, bigger fish would hide in the water don't eat not to move;
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.
Conversely, water temperature too low, fish and shoot, it will also function slow temperature, when appropriate, refus feeds sufficient oxygen, especially in the summer after the rain, the fish will quirks, foraging proactive, biting rate doubled, when some places have food, fish will through the special way to pass information, interoperability, and jump in food, water reservoir water level drops rapidly once the, the fish will show very frightened, hiding in deep water seldom eat, these are also fish habit characteristics.
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.
Anyhow, fish in life activities have a TongQiXing, directional sex migratory activities and collective behavior, we put this phenomenon called migration.
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.
Migration is one kind of phenomenon, fish is precisely relies on this kind of activity in some life period to meet its needs external conditions, make its population multiply get reliable guarantee.
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.
There are four main migratory fish migration and SuoErHuiYou: reproduction is warm, migration and wintering migration.
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；
We often found in fishing, spring carp, carp, catfish species such as JiaoWei from deep-water came to shallow water;
夏季雨后水库里的鲤鱼会溯流到上游进水口附近觅食；
The summer after the rain water garage carp will up rivers to upstream near foraging inlet;
仲秋以后鱼又从浅水来到深水越冬.
After half past autumn from shallow to deep fish and winter.
以上这些现象都在鱼的洄游习性范畴之内.
These phenomena are in fish migratory habits within category.
