Australian scientists have debunked the myth that fish have a
three-second memory, they can actually recall information for up
to five months.
"Fish can remember prey types for months. They can learn to
avoid predators after being attacked once and they retain this
memory for several months. And carp that have been caught by
fishers avoid hooks for at least a year," lead author Kevin
Warburton said.
The researchers at Charles Sturt University say that
three-second rule is "absolute rubbish. No one is sure where
they myth started but you needn't look any further than Finding
Nemo to know it exists."
Researchers trained young fish to associate a sound with feeding
time. Each time they played that particular sound…the fish would
return. They found minnows to be at least as intelligent as
rats.
Fish not only remember, they can increase their food-catching
skills and even carry out acts of deception. For example,
cleaner fish in reef environments act on their best behavior
when a larger feeder is nearby.
Warburton said: "What's fascinating is that they co-operate more
with clients when they are being observed by other potential
clients. This improves their 'image' and their chances of
attracting clients."
