Popular legend has it that goldfish have no memory, which is why they're happy to swim around in small glass bowls. (Actually, I had never heard this legend before, but my wife had.) Now researchers in the UK have debunked this legend.
The Telegraph reports:
The urban legend of the amnesiac fish has been dealt a new blow by a study which shows that goldfish can learn to avoid parts of their tanks where they receive electric shocks for at least 24 hours, probably longer... The new study was conducted by Rebecca Dunlop, Sarah Millsopp and Peter Laming at the Queen's University of Belfast and is published in the journal Applied Animal Behaviour Science... The Belfast team showed that goldfish can remember accurately where in their tanks they receive electric shocks. The stronger the shocks, the less likely the fish were to return to the sector of the tank where they had received them. The team reported similar results with trout.
Giving fish electric shocks sounds a little cruel, but I guess you can't test them with flash cards, or put them in a maze. Of course, the legend of the forgetful fish might have arisen because goldfish are
oxygen-deprived and near blindness from being kept in those little round bowls.

As an aside, it IS cruel to keep golfish in bowls....actually it's cruel to keep a goldfish in anything much smaller than 10-20 gallons per fish with LOTS of surface area. Another fallacy is that they "grow to the size of the tank" - they don't. They just die before they grow bigger due to poor living conditions.
Can you tell I'm a fishkeeper, lol? I'm also a mother and get livid on a daily basis when I see that schmuk elmo with his goldfish in that stupid bowl...... 😖
I used to work at a pet store in the fish dept. and I would get so upset with people who said things like, "It's just a fish" or "Well, if it dies, I can always get another one" and I think the low prices of certain easy to breed fish make this a situation that will last. I would have to hold back from getting all preachy at them, which sucked.
Rant, rant, rant....😛
I'm kind of divided on the whole animal testing thing in general. I don't like it, but I will half-heartedly concede that it's a necessary evil in SOME circumstances such as finding cures for horrid diseases, etc.
I don't however see the point of shocking goldfish just to determine whether or not they can retain memory. I can think of many other ways that don't involve pain to the animal that would generate the same result. It just seems like a pretty stupid thing to do when as mentioned previously, it's quite obvious to the people that keep them as pets that they DO have a memory. I can also think of a million other causes that could have used the funding they wasted on "proving" this and put it to a much better use.
2. I have no idea if the tests were cruel but simply based on the article, there's no indication that the shocks were painful. If you've ever worked with electricity, you've probably felt minor non-painful shocks that you immediately notice but cause no pain. I don't see why the scientists couldn't have used these.
Also, even if they used as strong a current as possible, the test wouldn't cost more than turning on a lightbulb for a few minutes. The funding for this experiment wouldn't have made a difference for another use.
Many fish can detect electric pulses (some detect prey this way) so I would imagine a very slight charge would be detected painlessly. If they administered the shocks this way, it would be much more humane than tapping on the glass (something I see many people thoughtlessly doing in pet stores).
Again, I have no idea about the exact nature of the tests but we should get more information before condemning them.
im just looking for a cool science project
