What kind of memory do fish have, how long can a fish remember

Many anglers, like most people, believe that fish have a very short memory. Unfortunately, this is a misconception, which is confirmed by various studies. They showed that fish have a very good memory, as for representatives of the underwater world.

This assumption (that fish have memory) can be tested by getting aquarium fish, and those who have them can confirm that they are able to remember feeding times. At the same time, they wait for the moment of feeding in the same way as animals. In addition, they remember the person who feeds them, as well as the people who live around them all the time. When strangers appear nearby, they begin to react to them in a completely different way.

Scientists argue that fish are able to remember their relatives and can live side by side for a long time, which can years.

What is the memory of fish

Investigating the life of carps, it was found that they remember their “friendsand spend in their environment, almost all the time. At the same time, age indicators can be completely different, which indicates the presence of a certain, separate “family“. Throughout the entire period, this group may break up into small groups, and then unite again, but the “friends” remain the same. In such a cheerful group, they rest, feed and move around the pond, in search of food. At the same time, they do not move randomly, but constantly along the same route. This indicates that the fish have a memory and it works.

Each group has the largest fish, which is the most cautious, which is likely to pass on its life experience to the younger generation. Otherwise, how could she have lived under water for so long and could not get either on a hook, or in a net, or in the teeth of a predator. During this time, she learned to recognize natural food and fisherman’s bait, a worm in the mud and a worm on a hook, real grain from plastic, etc.

All this happens in the underwater world, is fixed in the memory of the fish, which helps it to survive. If you catch a fish and then release it, then it will definitely return to its “friends” in its “family”.

What does a fish remember?

River fish, moving along the river in search of food, remember the places where you can eat throughout the day, and after dark, they can return to the same, safer place where you can spend the night without any problems.

They are able to memorize roosting places, wintering places and feeding places. Fish do not hibernate anywhere or where winter overtook them: they hibernate in the same places for a long time. If the memory of the fish did not work, it is unlikely that it could survive.

In this regard, we can recall such fish as perch, which lives in flocks. Without memory, this would not be realistic: after all, most likely, perch remember each other in a way that is not clear to us.

You can also remember about the asp, which feeds on a certain territory of its own. At the same time, he walks the same route every day, chasing fry. Also, he clearly knows the boundaries of his territory and does not swim wherever his eyes look.
