How many minutes does a fish have and how long is a fish s memory

It was once believed that fish memories could only last for 3 seconds, and this impression was reinforced by the forgetful little fish Dori in the cartoon "Finding Nemo". But scientists' research has disproved this view. They found that fish not only have a memory of up to 5 months, but also have a certain "sense of time".

This has contributed to the development of new fish farming methods. According to the British "Daily Mail" 6**, three scholars from the Israel Institute of Technology, Boazzi Zion, Assaf Barki and Ilan Kapras, carried out an experiment: every time they feed the fish, they use a loudspeaker to make a certain sound.

After training for a while, as soon as this sound is heard, the fish will come back to eat. After 1 month, the scientists put the fish in their natural waters and let them swim freely. After 4 to 5 months, the 3 people again ** the sound of the initial training, and the fish followed the sound again.

Other scientific studies have proven that fish have the ability to remember and learn, and are even as intelligent as birds and mammals. Scientists at the University of St. Andrews in Scotland have found that minnows, which look weak at about 15 centimeters in length, may be smarter than mice. Mike Webster, a scientist involved in the study, said

Many fish can learn to walk the maze, identify other fish, and remember what kind of fish are stronger competitors than themselves. A study by the University of Plymouth in the United Kingdom also found that goldfish not only have a memory of up to 3 months, but also can distinguish time. The researchers first trained the goldfish to push the switch for food, and then adjusted the switch so that it could only be pushed for one hour a day.

Amazingly, the goldfish adapted to this change: whenever the "meal" time approached, they would gather around the switch. It was clear that they knew that it was time for dinner.

How long does a fish have to remember, don't say it again, the fish only have a memory of 7 seconds.

The fish only remembers for seven seconds, and after seven seconds it doesn't remember the past, and everything becomes new again.

The memory of the fish is more than 7 seconds, the minimum is one month, and the longest can reach several months or years, of which the memory time of the Zen hail coarse goldfish is more than 3 months.

Although the rumor refers to the goldfish's memory for only seven seconds, the ideal is plump, but the reality is skinny. Paradise fish have a relatively long memory in fish, which can last up to three months, and He Zhen doesn't look at their size as much as goldfish, but their memory is almost 3 times.

When this fish encounters a strange goldfish in the pool, it will swim around curiously, looking at the new "strange neighbor" until it loses interest. If the Paradise Fish and the Goldfish meet a second time in the tank, they will quickly discover that they are old acquaintances and lose interest in exploring again. Experiments have found that such memory can be maintained for at least 3 months.

Types of fish

The types of fish include crucian carp, grass carp, silver carp, bighead carp, herring carp, carp, sturgeon, shark, yellow eel, mandarin fish, etc. Crucian carp, referred to as crucian carp, is commonly known as crucian carp melon seeds, moon crucian carp, soil carp, thin head, carp, cold carp, happy head, crucian carp, river carp. It is commonly found in Eurasia and is a common freshwater fish, belonging to the genus Crucian carp of the Cypriniformes subclass of radial-finned fish.

Grass carp, commonly known as grass carp, grass carp, grass root, etc., is a carp of the genus Cyprinidae. Grass carp have a lively temperament, are very adaptable and active, and swim quickly. Silver carp, also known as silver carp, silver carp, jumping silver carp, silver carp, belongs to the order Cypriniformes, carpidae, is one of the famous four major fish, the four major fish are:

Herring, grass carp, silver carp, and bighead carp are typical filter-feeding fish.

Depending on the type of fish, fish have memories that can be as short as three days or as long as at least three months. Fishes are the oldest vertebrates, and the earliest known fish fossils were found in the Late Cambrian strata about 500 million years ago. At present, there are about 32,100 named fish species in the world, mainly distributed in marine and freshwater, and two-thirds of the fish in the ocean.
