What is the memory span of a fish2007-11-24 23:41:48

Is it really 5 seconds?

Answers:

Forget the old jokes about goldfish: a University of Plymouth psychologist wants to explode the myth that fish have a three-second memory span. Dr Phil Gee claims fish can remember things for at least three months and can even tell the time - or at least sense what time of day it is.

He said fish can learn that pressing a tiny lever in their tanks can dispense food at certain times of the day.

Dr Gee said: "Scientists have known for a long time that fish, even goldfish, have more than a three-second memory. In fact, research has shown fish have a memory span of at least three months.

"Research has also shown that fish can learn to distinguish between different shapes, colours and sounds."

Many people have never stopped to think about it, but fish are smart, interesting animals with their own unique personalities鈥攋ust like the dogs and cats we share our homes with. Did you know that fish can learn to avoid nets by watching other fish in their group and that they can recognize individual "shoal mates"? Some fish gather information by eavesdropping on others, and some鈥攕uch as the South African fish who lay eggs on leaves so that they can carry them to a safe place鈥攅ven use tools.

Nobody knows but people will make wild statements like 2 or 3 seconds but they cant back this up. We just dont know.

..and does it matter in the slightest ?

i always thought 3 seconds, although i do not think this is true as my fish in my lake seem to know when i want to catch them, once they have been caught, they swim to the other end of the lake

Does anybody REALLY know, unless you are a fish?

it depends on the type of fish
