Researchers from the Technion Institute of Technology in Israel trained young fish to associate a sound played through a loudspeaker with feeding time.
Each time they played a particular sound, the fish would return for food.
After a month of training, the fish were released into the sea, where they were left to their own devices.
Four to five months later, when they had become adults and ready for marketing, the sound was played again and the fish returned.
Applied to fish farming, the technique would allow ‘trained’ fish to be released into the sea, where they would mature naturally until ready for the table.
Previous studies have shown that goldfish are capable of remembering and learning – and that they outshine trout in the intelligence stakes.
Scientists at St Andrews University in Scotland found minnows to be at least as intelligent as rats.
Researcher Dr. Mike Webster said at the time: ‘A lot of people have the image of a goldfish with a three-second memory – and that’s not the case at all.
’There is a lot of evidence now that fish are no dumber than birds or many mammals – and in many cases they are just as intelligent.
’Many fishes – such as minnows, sticklebacks, and guppies – are capable of the same intellectual feats as, for example, rats or mice.
‘They can learn their way around mazes, they can learn to recognize other fish, and they can remember which individuals are better competitors.’
According to research at Plymouth University, goldfish have a memory span of up to three months – and can even tell the time.
The fish were trained to nudge a lever to get food. When the lever was adjusted so it would only work during one hour each day, the goldfish adapted, learning only to press the lever around the right time.
They even clustered around the lever as feeding hour approached, apparently remembering it was nearly lunchtime.

Supposedly experts say that goldfish have a memory span of 29 seconds. Sure hope that Ziggy’s school gets out in less than 28 seconds from now!

There’s so much room, it’ll probably get lost.
