It is said on the Internet that the memory of fish is only seven seconds, is it true?

Many people think that fish only have 7 seconds of memory, but is that really the case? In fact, no, compared to other organisms, the memory of fish is very strong, it can have a memory of a few days or even months or even a few years, not only 7 seconds, in fact, scientists in some countries have also done fish memory experiments, confirming that the memory of fish is not only 7 seconds, they will put the fish into a maze to find, to the exit can be free, two small fish were repeated by the experimenter in the maze to walk the maze, two small fish in the number of experiments gradually formed in the memory, So he memorized the route of the exit, which could take a few minutes at the beginning, to find the exit within a minute, and it turned out that the fish can rely on memory, and he may be like a person who has walked in a place for a long time, and he will remember the general map to distinguish which road is the exit. <>

So our previous perception of fish is wrong, through experiments to prove that fish can rely on their own memory to find the exit, maybe his memory is not as long as we humans, but it can be as long as months or even years, and the size of the brain of fish is not the same, there are many large fish are very smart, but to judge whether a fish is smart, can not look at its size, it is equivalent to us humans, some small people are very smart, but some tall people are stupid, Therefore, we cannot judge the size of a fish when we judge whether it is smart or not. <>

The memory of the fish is definitely more than 7 seconds, they can remember what they want to remember, and they can survive well in the water, maybe when they encounter a big fish attack, they will react very quickly in the **, so the fish is also very smart, as for the fish only seven seconds of memory, this sentence is without any scientific basis, because scientists have repeatedly done experiments to prove that the memory of fish actually has a long time. <>

Not really. Fish have more than seven seconds of memory. According to the Proceedings of the National Academy of Sciences, depending on the type of fish, the memory of fish can be as short as three days and as long as at least three months.

It should be true, because from the point of view of feeding the fish, it is known to be true. Feeding the fish must be fed regularly, and you can't keep throwing fish food into it, otherwise the fish will keep eating until you die of eating.

Not really, fish have more than 7 seconds of memory, scientists in the United States have tested it and come to the conclusion that fish have memories for months.

The fish's memory is much more than seven seconds.

In 1965, researchers at the University of Michigan in the United States conducted an experiment with goldfish. They put the goldfish in a very long tank, then shoot a bright light at one end of the tank, and after 20 seconds, release an electric shock at the end of the tank that shoots the bright light. Soon, goldfish develop memories of electric shocks, and when they see light, they quickly swim to the other side of the tank to avoid the electric shocks before they are released into the water.

The scientists who designed the experiment found that with proper training, the goldfish could memorize the tricks of dodging electric shocks for up to a month.

The fish has a memory of more than 7 seconds.

In 1965, researchers at the University of Michigan in the United States chose a long fish tank to test the memory of fish. At the beginning of the experiment, the researchers shot a bright light at one end of the tank, and 20 seconds later, released an electric shock at that end. Then, they repeat the same at the other end of the tank.

Soon, the goldfish formed a memory: as soon as it saw the light, it quickly ran to the other end of the tank to avoid the electric shock. Experiments have confirmed that with reasonable and effective training, these clever goldfish can firmly remember how to dodge electric shocks within a month.

Goldfish have always been thought to be simple-minded, but Australian researchers have found that fish are more intelligent than people think. After more than 10 years of studying fish, Kevin Wobton, an assistant researcher at Charles Sturt University's Institute of Land, Water and Society, found that fish can remember the type of prey for months, that is, they know to avoid predators after being attacked by predators, and this memory can last for months.

In addition, scientists have also done some experiments on fish memory, and the results have proved that fish memory is much more than 7 seconds.
