I think they don't have such a short memory. I kept fish for many years, both tropical and coldwater, and some of them can definitely learn. Many kinds of fish will learn to gather at the surface when someone goes near their tank or pond, because they know that this usually means food. This happens even if they were fed more than 2 seconds ago! Almost all of them learn to avoid a net. Goldfish and carp are among the best learners, despite the reputation of the goldfish. It is said that a carp will never be caught on the same bait twice, because if it is caught and released it will remember to avoid that food.
I don't know about marine fish though...

Salmon return to exactly the same river to spawn after up to five years at sea... That must take a bit of remembering!
Oh they are definately smartish, our goldfish and carp will come to the side of the pond en mass when Colin goes near because he feeds them but when I go there they all bugger off rofl that is quite good I think because they recognise the person not the animal or colour (we do change our clothes 
)
I think we have all seen a difference in the behaviour of fish in the sea when we hunt the same spots regularly, they do keep there distance more after a few visits

This could be a bad move on my behalf so be gentle .
Latest reports on fish and fish behavour are now looking into the difference between memory and İnstinct, a fish will instinctivly swim forwards not because it has remembered to but he/she İnstinctivly does.
salmon instinctivly return to their spawning grounds but the question is do they remember or is it instinct. a fish in a bowl will instinctivly swim away from a net because instinct tells him/her its Danger, even a ball which cannot even catch it will make it shy away(eg:do you say to yourself OH my god a Great White i had better get out of here; maybe not ,you will however instinctivly move slowly to where you know you will be safe and most cases you wont remember doing it, but later may recall what you actualy did to get away).and brag about it. .The fish Brain is a functional one and is designed to carry out the everyday chores it has mainly, feeding, mooving and Breeding
there are however contradicting reports that a fish may have a very limited short term memory hence the fact that Some come back to see why you shot at them(if you missed) :waterwork but then later they may remember what went on and next time the long term memory will instinctivly inform them of Danger. This could also be the case for Carp bred in amusement parks, they will suck your finger if you hold in the water because they have no memory of Danger in the long term İnstinctive memory but a Carp in a fished water will hide away and not suck your finger because his wife just got draged out and molested and placed back in the water so instinctivly he wont go near anything he doesnt know but after a while curiosity will get the better of him and he too will get the hook.....................Open to more coments

My neighbour has a pond that is 9m deep and about 3m by 4m across ... it is stocked with MASSIVE koi carp... I think that I can hit it from my garden with my 100cm speargun - is this legal ?
At least I might give it a whirl diving in it when he goes on holiday - any thoughts ? Are there any poisons in pond water ?
Can you eat carp ? I thnk a 9m aspetto might be quite productive.

That is my ambition - to have a huge pond which I can dive in with koi carp. It won't happen for quite some time though. :hmmportinfer said:
I'll have to make sure my neighbours don't like spearfishing. If I discovered someone had been eating my priceless koi carp there would be consequences.

Weeeelllllll, since the market price on koi runs into something the same as a good automobile, perhaps a more prudent course of action should be considered. Consequences? Hooo-boy!
Huan, most of northern Europe would be perfectly to let you go on believing that so long as they get to eat all the carp you don't want.

Yep you are correct , I don't like freshwater fish full stop.
The only reason the northern europeans eat crap is because they don't have access to saltwater fish.
I believe Carp is a big christmas dish in Poland.
Even Flatfish don't do much for me, give me oily pelagics anytime.

How about Brook trout, Steelhead and Brown trout.
I think those are pretty tasty. Not to mention Salmon.
mmm and lets not for get crayfish fed northernpike or broiled largemouth bass.
catfish from a freestone river is pretty darn tasty to yum.

I'd never shoot his fish really... but I would like to have a go in his pond - he showed it to me a while back and you just peer in ... and in... and in - seriously deep and also steep sided (on old septic tank that he changed the purpose of - well to a degree according to Huan's description) - you can see koi all the way to the bottom - his garden is seriously neat too... mine has a nice 'rockgarden' of building rubble and weeds - I WILL have heating this winter - determined.... (but also going out til late in the evenings and then diving during the weekends doesn't really help my cause....)

Fish and memory.. hmmm
I used to dive stingray city three times a week sometimes, and there were some particular rays that used to allow me to do all kinds of things with them, and some that didnt. The ones that did would rush towards me every time i went down, as if they remembered the last time. So did that very large green moray eel
perhaps its just coincidence... i also found the same thing with my "mate" from the lagoon in Maldives, she used to let me come real close sometime.

Its both - the instinct is to return but the information about which which river has to be remembered. Captive bred Par return to the river in which they are released.
Not sure about this as when you miss a fish you don't do it any harm whatsoever (you could've had me bleedin eye out with that thing mate!) but definately in the case of Carp they are not only remembering the stress (pain? controversial!) of being caught but also the finer details of the bait which they took before they were caught.
Any study of fish memory will certainly come back with 'surprising' results about how good fish memories are, except it wont be that surprising as humans allways underestimate the intelligence/consciousness of animals they eat - makes it more pallatable!
