高手夜钓钓大鱼,你夜钓却喂蚊子!学这些技巧,一晚钓满两个鱼护

夜钓,顾名思义就是夜晚进行户外钓鱼。现在有很多钓友都喜欢进行夜钓,尤其是夏季和秋季的时候,夜钓的人特别多,一到晚上就可以看到他们的身影。

我钓鱼也有几年了,也有不少夜钓的经历,夜钓确实好处是比较多的,也容易上鱼,上的鱼也比较漂亮。今天也给大家聊聊夜钓的一些事情

夜钓的优点:

1、不用被太阳晒黑

很多钓鱼人在他们钓鱼之前,他们的肤色都是比较白的,但自从钓鱼后,他们的肤色慢慢就变黑了。尤其是脸和手是最容易晒黑的。所以钓友为了不用被太阳晒黑,他们就放弃了白天去钓鱼,从而选择夜钓。

2、小鱼不闹窝

夜钓的好处就是没什么小鱼闹窝,上大鱼几率大,而白天就不行了,白天小鱼闹窝特厉害,小鱼一旦聚窝,就会一直闹窝。基本上饵料一到水面,就被小鱼抢食,饵料很难到达底层,想钓大鱼几率偏低,夜钓刚好相反,夜钓没什么小鱼闹窝,饵料可以顺利到达底层,钓到大鱼几率偏大。并且大鱼在晚上会到浅水岸边觅食。

3、鱼的警惕性降低

鱼的警惕性是比较高的,但到了晚上由于光线比较昏暗,鱼就会放松警惕,大胆进食。并且有的鱼喜暗不喜光,比如鲶鱼、黄骨鱼都是喜欢晚上出来溜达的。

啰嗦了那么多,咱们言归正传

夜钓装备选择

必不可少的夜钓装备:

鱼竿(可以不用带备用杆,事实证明很少用到)、照明手电筒(最好用荧光棒不用蓝光)、线组(夜钓线组大一些)、漂(不用带漂盒,两支和鱼竿放一起,子线用一个小线板)、炮台、蚊香、抄网、鱼护、打火机、吊床、小凳子(如果不带,野外做一个凳子很方便,带一个蛇皮袋里面填充草和树叶即可),饮料零食。

我们夜钓都是几个人一起约好,经常就是装备互补,你带鱼护我带抄网,你带吊床我带备用杆,你带饵料我带窝料,你带子线我带蚊香。很多东西都可以互补,这样就不用每个人都把东西带上。

还有一件,失手绳。夜晚一般钓大物的几率会比白天高,大鱼一般喜欢晚上靠近岸边觅食,请备好失手绳,失手绳遇见大鱼有一定的缓冲能力,不会让你措不及防的被切线,也不会让鱼竿丢失!很重要!

夜钓钓位选择

对于夜钓钓位的选择方面,石头的观点是以食物为选择依据的。鱼道,水域的深浅交接处这些白天重要的钓位在夜钓的时候,显得并不是那么的重要了。因为鱼儿在晚上活动就是为了觅食的。

1、选择钓水草边

我们知道,水草处是食物较为丰富的地方,但夜钓时尽量不要选择水草茂密的地方哦!因为在晚上没有太阳,水草也在消耗水中的氧气,所以晚上水草处的溶氧量是不高的。虽然是这样,我们可以选择钓草边,钓比较稀疏的水草处。石头认为,钓点选择距离水草有1—2米左右就可以了。

2、选择水域进出口的两边作为钓点

水域进出口的两边,这些地方属于水流较为缓慢的地方。浮游生物和水中其它杂质聚集的地方,这些都是鱼儿的食物。选择这里还有一个好处,这个地方不存在溶氧量低的时候。

3、选择水域的回水湾作为钓点

这个地方和水域进出口两边的原因大致相同的,主要是食物较为丰富的。

4、选择水域的亮光处作为钓点

我们知道,灯光是可以诱鱼的。在漆黑的夜晚,水域里有灯光照射到的地方,如果适合作为钓位的话,可不要错过的哦!因为这很有可能是一个不可多得的钓点。石头夜钓的时候,就喜欢寻找这些地方作为钓点,往往鱼获还不错的哦!

一定不要选比较陡峭的,也不要选择岸边松滑的地方。

夜钓饵料味型选择

1、气温低时夜钓饵料味型的选择

深秋、冬季、初春,这些时候气温较低,鱼活性差导致鱼口较轻,爱吃不吃的感觉。那这个时候在饵料味型上就有讲究,重香重腥效果是比较不错的。

另外,鱼都有追逐活饵的习性,因为活饵不但有腥味,还是活动的,鱼当然喜欢。我在冬天夜钓时,如果粉饵不好的话,那就选择活饵,往往效果是很不错的,特别是冬季用红虫。

2、气温高时夜钓饵料味型的选择

夏季,初秋这个时段温度高的时候,鱼对荤味是不太感兴趣的。有些钓友不管是白天作钓还是夜钓都不加腥的,对于这点我不是很认同。从我多年夜钓经验来看,气温高的时候夜钓加腥,效果还是不错的。但在加腥上要注意,不要过多,一般是在百分之十到二十左右比较好。

3、气温适宜的时夜钓饵料味型的选择

这个时段多数为仲春、中秋的时候,这两个时段是一年之中的两个钓鱼黄金季节。这两个时候,鱼儿因为生理的需求,往往显得“饥不择食”,所以在这个时候饵料味型的选择就较为广泛了。不管是那种饵料味型都是可以的,只要不是很怪就行了。

夜钓灯光的选择

既然是夜钓就少不了灯光的。夜钓的灯光一般有蓝光,紫光,白光,黄光,这四类光线各有各的好处,各有各的弊端。

比如:白色光,比较亮,对于我们钓鱼人来讲比较合适,但白色光也是因为较亮容易惊鱼。黄色光较为柔和,宜诱鱼,但同样易招蚊虫。紫光,看漂较为清楚,但时间长了容易引起视觉疲劳对身体不好。

而蓝光不管是在光线的敏感度,还是对于眼睛的刺激上是这四种光线较为适宜的,这也是钓友们夜钓选择蓝光居多的原因。

还有,夜钓的时候,灯光尽量和水面平行。抛竿时尽量抛准一点,免得灯光移来移去造成惊鱼的现象。

夜钓的安全方面

安全是夜钓的重中之重,我们应该放在首位,尤其是在野外夜钓。蛇、蚊虫、落水都会对我们的安全产生威胁,下面的一些野外夜钓的技巧请你一定要牢记:

1、在草多的路上一定要穿靴子,就是那种长筒雨靴,到膝盖的,这样能避免绝大多数的蛇类攻击。我曾经在野外看一个广东的兄弟穿着人字拖去野外钓鱼,那附近我看到过好几次银环蛇,这样实在太危险了!

2、走路时一定要打灯,如果特殊情况在穿着靴子路况熟的情况下可以不打灯。如果没有穿靴子,一定要打灯请进,看到深色、绿色的条状物一定要看清楚再走。

3、手上拿一根杆子或者棍子,看到像蛇的东西敲一下。就算冬天没有蛇,也可以防野狗。

4、切忌一个人单独出去夜钓,最好找个伴相互有个照应。如果实在没有那就不去,虽然这个世界上没有鬼,但人的心里有。

5、如果要去的地方比较陡峭,屁股后面用一个大瓶的可乐瓶子拧紧绑在皮带上面,关键的时候能救你命!不要以为水性特别好,淹死的大多是会水的。我水性不错,四肢捆绑都保证不沉水。但曾经在水中间小腿抽筋差点要了老命,要不是造物主眷顾,估计坟头草两米了,后来我下水一定穿救生衣。

6、蚊香是必备,除非是冬天没有蚊子了。切忌使用花露水和驱蚊水,虽然驱蚊效果不错,但是影响鱼口。吃大蒜对防蚊虫也有不错的效果。

7、不论多热,都是长衣厚裤,把裤脚扎入袜子里面,切忌短袖!

8、到钓点之后,找一根棍子在钓点附近草边和灌木边敲打,打草惊蛇!

9、通宵而且开车的钓友,一定要在2-4点睡两个小时左右,为了第二天返程的开车安全。如果周边有树,推荐睡在吊床上面,旁边生一堆火,保暖的同时驱蛇虫。

10、看到蛇了不要害怕也不要激动,大多数情况下它会自己离开,除非你踩到它了。当然你会捕蛇,也可以把它捕捉之后找一个其他地方放掉。至于其他地方是哪里我这里就不多说。

11、晚上有老鼠来吃你饵料,翻你的包包,拍手吓它就离开了。千万不要去踩或者捉,靴子都能给你咬穿,老鼠毒性大,被咬了没有一两千块下不来台。

夜钓虽然好处多多,但危险源也是比较多的,所以我们夜钓时一定要做好安全措施,这样夜钓才是安全的。

音频文本:

Alice: Hello and welcome to 6 Minute English. I’m Alice…

Neil: And I’m Neil. So Alice, what’s your ideal place to be?

Alice: Curled up on the sofa with a good book in front of a log fire. Last night it was very cold.

Neil: Well, for me, lying in a hammock under a palm tree on a tropical beach with a cool breeze. I don’t like when it’s too hot.

Alice: Yes, true. Humans don’t cope well with extremes of temperature but some species do. The subject of today’s show is extremophiles–these are microorganisms that have adapted to live in what we would consider to be extreme conditions. For example, living in near boiling acidic water or frozen at the bottom of an Antarctic lake.

Neil: Those do sound like pretty extreme conditions.

Alice: Yes. The thing is, what sounds hostile–or unfriendly–to us, are perfect environments for extremophiles and in fact they wouldn’t survive without them. Now, are you tough enough to face up to today’s quiz question, Neil?

Neil: I think so.

Alice: Alright then, here goes: which US National Park is home to geysers–or hot springs that shoot hot water and steam into the air–which have extremophiles living in them? Is it…

a) Grand Canyon?

b) Death Valley National Park?

Or c) Yellowstone?

Neil: That’s easy – it has to be c) Yellowstone.

Alice: OK, well we’ll find out if you got the answer right later on in the show. But, moving on, now, Neil, did you know that extremophiles belong to an entirely different group of living things to other animals and plants?

Neil: No. I imagined extremophiles would be like insects, because insects are pretty tough, aren’t they?

Alice: Yes, that’s true. But remember, extremophiles are microorganisms–they’re really tiny. Let’s listen to Ian Crawford, Professor of Planetary Science and Astrobiology at Birkbeck University of London. He tells us how in the 1970s a scientist called Carl Woese identified a new kingdom of living things that he called ‘archaea‘ – meaning ‘ancient ones’. The extremophiles belong to this group.

Well, the old tree of life idea basically talked about empires if you like, of plants, and animals, and things that we can see, essentially. We put a great deal of emphasis on large organisms and the traditional distinction in biology between botany and zoology. What it really did was say ‘that’s all wrong – there’s really only three major groups in life: there’s the archaea, the bacteria, and the eukaryotes, which is all of this complex life’; and so it kind of put humans into a small corner of the tree of life next to plants and whatever else. It kind of squashes us again after being the centre of the universe.

Neil: So botany is the study of plant life, and zoology is the study of animal life. But maybe you can explain ‘archaea’, and ‘eukaryotes’, Alice.

Alice: Archaea are a group of single-celled microbes similar to bacteria but different to all other known types. Eukaryote is the scientific term for organisms with a much larger and more complex type of cell– and this group includes all animals, plants, and fungi.

Neil: But why are archaea so important? Why do they need a whole biological domain to themselves, while we humans get squashed up in one domain with plants and fungi?

Alice: Well, Neil, it’s likely they’ve have been living on our planet ever since the Earth became habitable – and that’s billions of years. And they are still living and thriving in a whole range of different environments today.

Neil: And when something is thriving it means it’s doing well! So tell us about where they live, Alice.

Alice: Some live in hydrothermal vents – holes in the ocean floor hundreds of metres down where there’s lots of pressure and no sunlight. And mineral-rich superheated water is coming out of the Earth’s crust and then flowing out through these holes.

Neil: I see… Well, what about cold-loving extremophiles?

Alice: Well, scientists have found them in hidden lakes trapped beneath ice sheets hundreds of metres thick in Antarctica. It takes days to drill through the ice to reach the water.

Neil: And how do they survive down there?

Alice: Well, these microbes have found a way of getting energy from certain minerals like iron and sulphur present in the water.

Neil: That sounds clever for a microbe – how did they figure that out?

Alice: It isn’t a question of cleverness – it’s a question of adaptation. Extremophiles are extremely well adapted to their environment and they appeared on Earth much earlier than more complex life forms. Let’s hear from Nick Lane, Reader in Evolutionary Biochemistry at University College London.

The origin of the Eukaryotic cell, it seems to have happened once, it took about 2 billion years before that happened. Then there was kind of a great leap forward at the cellular level, but another billion years went by before we see animals.

Neil: So, basically, the animal kingdom is much newer than the archaean kingdom.

Alice: Indeed. And now it’s time for the answer to today’s quiz question, Neil. I asked: which US National Park is home to geysers that have extremophiles living in them? Is it… a) Grand Canyon, b) Death Valley National Park or c) Yellowstone?

Neil: And I said c) Yellowstone. I must be right.

Alice: Yes, Neil, you are right – it’s Yellowstone National Park. Every year, scientists discover remarkable new microbes in Yellowstone’s hot springs, with implications for medicine, agriculture and energy, as well as offering clues to the formation of the earliest life on Earth.

Neil: Very interesting. Now, here are the words we heard today:

extremophiles

hostile

geysers

microorganisms

botany

zoology

archaea

eukaryote

thriving

hydrothermal vents

Alice: And that’s the end of today’s 6 Minute English. Don’t forget to join us again soon!

Both: Bye!
