Introduction: How to Make a Fish Trap in 30 Seconds

If you have a plastic bottle and a cutter/knife/scissors, that's great --- you can make a fish trap in a minute -- it is so satisfying to catch a fish!
That is the reason I make this Instructable.

Features of this design:
Rocks in the bottle --- sinks the bottle; stabilize the bottle against the waves.
Small bottle --- easier to lift when filled with water; will be harder for small fish to escape through this small opening than the 5L bottle opening.
Cut the bottle at a low level --- the top and the bottom part will fix together firmly without tape, glue, fishing line, or wire.
Not to use fishing line --- easier to opening/close the trap; easier to make the trap.

This is excellent for catching small bait. The plastic bottle can be any size, but I prefer 2 liters rather than 20 oz. or smaller ( though they work just as well in a pinch) I like to add a rope and bright float to them, like a solo cup or anthing that catches your eye when looking for them as markers to find them again, I leave them out for a few hours at a time. Thank you for making this instructable. :)

try with a bigger bottle with a larger cap ;) and drill the bottom of the bottle ;) oh and...what have you done are more than a minute compressed in 30secs;)

torned00 (author)Timofte Andrei2010-10-26

what if a small fish just ate all the trap and easily gone out because of the hole.

RebeccaH7 (author)torned002015-10-05

the plastic disorients them, the trick is they don't see the hole top get back out. :)

For all of you that think that killing fish is wrong, this is a fish trap that (I'm guessing) is mainly used for catching fish for bait (that's what I'll use it for) or for putting in a fish tank/ pond.

And are the fish still alive?

ilikecake3 (author)2013-06-11

What should I put as food/bait?

enemigo (author)2012-12-02

same concept as a fly trap the fish/fly enter for the bait but when it's time to exit most all of them go to the top and progress round and round looking for the opening, almost never going to the center where the opening is. They don't have the capacity to think like we do, so their lack of reason traps them, not a closed door.
(in response to "torned00" )

enemigo (author)2012-12-02

sand in the bottom uses a lower profile and thus the fish have a harder time finding the opening to get out.

no offence meant to anyone but...... not hunting would be more cruel than most people could imagine some people i dont know if it was p.e.t.a. or someone else bought all the deer tags in my area one year my aunt has a 80 acre farm it was terrible to watch, the population of deer had exploded over the previous 2 years after deer season with no kills we got to watch deer dying from disease and starving to death i am a fisherman i am a hunter i am a conservationist and i am a realist i do believe and practice take only what you can eat and eat whatever you take i have no ill will for vegans and vegetarians i have some friends who practice the lifestyle but as i have explained to them i hunt and fish because of my love of nature better a quick bullet than a week of starvation i admire the beliefs and the conviction of people who abstain from eating meat but if no one hunted/fished what would we do about the over population of animals due to the lack of natural predators the only predators they have now are hunters and cars sorry about my little tangent i did love the trap btw i am trying to make a bigger one thanks

it looks easier then catching a fish with a ill try it :)

trans4mation (author)2011-05-15

Nice tutorial! And might I add we DID NOT evolve.

Ckeranen (author)2011-04-20

I do this when I go fishing. You can use the smaller fish for bait.

Dukeeey (author)2010-08-20

I tried this before and would like to tell you all that the fish doesn't die unless the trap is made wrongly. When you take it out the water, water stays in the bottle so the fish survives and you just take the top back off then let the fish go again. If you leave a sharp edge, the trap is too small, leave it in there for too long or put oo many rocks in it, the fish could die.

lilrocker90 (author)2010-07-28

hmmm thats a cool concept, but i wouldnt KILL a fish if im not going to eat it, and that fish is too small to eat so i would use this concept to make a bigger trap... nice though

maurice1993 (author)2009-09-02

one time I cath 104 fishes in about 10-15 minutes with this tingh! it realy works!

covey12 (author)maurice19932009-09-03

please use proper grammar, i mean there's a built in spell check lol

geek12597 (author)covey122009-09-03

who cares ?

maurice1993 (author)geek125972009-09-03

thanks for defense!

becauseican (author)maurice19932009-09-04

o u dont no english then thats great to be bilingual. alot of people on here natively sspeak english and have much worse grammer than u.

maurice1993 (author)becauseican2009-09-04

well, that takes a lot of pounds off my hands... yeah, I'm learning english... one day I get there!

forgoten (author)maurice19932009-09-04

Umm, you speak great English (well, type really). If your native language is Latin based (European and the like) your great. non-Latin your amazing, the deference is so much.

jr.tuckluck13 (author)forgoten2010-07-16

Not to start an argument here, but English is not Latin-based. It is Germanic.

plumber4 (author)forgoten2009-09-13

you're great. you are great. get it? i know that the two are very confusing. keep practicing. don't forget that there is also DIFFERENT their - they're - there. english cna get confusing. most people that speak it as a native language don't (do not) get it.

maurice1993 (author)forgoten2009-09-05

Man... so many discussion I've been created... rsrsrs Yes, my native language it's Latin based(portugese, I live in Brazil)... Thanks for the praise... This makes me fell able to continue... But I admit you.. Sometimes I still have to run for the dictionary.... rsrsrs lol. ( I guees it's betterI pay more atention to the capitalization of the words.. LOL (-; )

sgt_pinky (author)covey122009-09-03

Says he who uses 'i' instead of a correctly capitalised 'I', does not start the sentence with a capital, and finally finishes with an uncapitalised or punctuated acronym. Ouch.

madhops0620 (author)sgt_pinky2009-09-04

Uncapitalized is spelled with a "Z", not an "S".

rich70734 (author)madhops06202009-09-05

This chain never ends. Save yourselves, Gentlemen. I'm going down with the ship!

sgt_pinky (author)rich707342009-09-06

Yourzelvez is spelt with two z's, and spelt is spelled spelt. Oh...wait...

BillyTheGoat (author)rich707342009-09-06

its pronounced "dıɥs" ɥnp.

maurice1993 (author)BillyTheGoat2009-09-06

What is..... "dıɥs" ɥnp I'm not sure I can make these on my keyboard...

sgt_pinky (author)madhops06202009-09-06

In Australia it's not. And everyone know we're correct :-P Hehe.

maurice1993 (author)covey122009-09-03

Ok, I don't know how to use grammar properly, but, I STILL DON'T KNOW HOW TO TALK ENGLISH PERFECTLY! And I'm learning this, ok? maybe in the future I can do this right :D

flashanimator (author)2009-09-02

Where would we get snails, because i dont think there are many around where i live? Otherwisse nice Video will try with different baits if not.

Brooks C. (author)flashanimator2010-05-22

Check if there are streams, ponds, or lakes in your area.  You can usually find them attached to rocks. 

Samuel C (author)flashanimator2009-09-13

I are not sure where you are, but they usually stick to the rocks at the shallow water. I can find them in the sea and river, Asia and Africa.

spike2271 (author)flashanimator2009-09-03

normally there are snails around water like on the sand/mud and you know fish like water so probably can find some snails.

geek12597 (author)flashanimator2009-09-03

dont necessarily have to use snails. squid or bread would work.

chrisrich (author)2009-09-09

Great post....minus all the inane banter...I am going to try this soon in fresh water. Not too sure what I should use for bait, but I will definitely use a larger bottle and connect it to a line so I can toss it way out into the lake or river.

I hope my spelling, grammar and punctuation meets with the high standards of this forum...

 Hi Chris.  As already posted, just use anything stinky for bait (something giving off a strong odor).  Also, just to keep in line with out Instructables "be nice" comment policy, chill out with the arrogant stuff, as it isn't really constructive. 

Brooks C. (author)noahnoah2010-05-22

I agree, but make sure the bait washes off easily.  I got stinkbait smeared in the back of my car when I was fishing in Iowa in the Mississippi.  The stench stayed there  for weeks, no joke.  

kld435 (author)chrisrich2009-10-19

hey man, depends on were ur at, but in the mindwest united states, a worm would catch bluegill,crapie, perch, or maybe bass, but some chicken liver would work real nice for catfish in a river with a bigger version of this.

Samuel C (author)chrisrich2009-09-13

Be aware that your line is strong enough. The large bottle you use will fill with water; and if the bottle got stuck among the rocks, you may lose your bottle and your fish.

Grace Robert (author)2009-10-04

I check it whenever I want to.

steed1172 (author)2009-09-28

how often do you check for fish?

ruthmeitaifan (author)2009-09-19

I think we can use similar design to catch any fish, even shark, as long as the inlet/outlet is relatively smaller than the bottle/tank itself. I found some similar designs of fly-trap and mosquito-trap, too.

ruthmeitaifan (author)2009-09-19

Depending on the strength of the current, sometimes I need to make several holes and tighted up the two parts of the trap with strings. In stream or seashore where the current is slow, I just do it as shown in the video.
