The memory of a fish has a few seconds 30, and the memory of a fish has a few seconds

It is said that the memory of the fish is only 7 seconds, and after 7 seconds, everything starts again, of course, this is a literary statement, accompanied by a poetic and picturesque statement. In reality, fish have a high IQ and an amazing memory.

1) Feeding memory: Take the ornamental fish we often raise, after a long time of careful feeding, the ornamental fish can remember our movements and faces, and once a stranger feeds, the fish refuse to eat. This is enough to prove how strong the memory of the fish is.

2) Return to their birthplace to lay eggs: Sea turtles are a proof that turtles return to their birthplace every year, and they can remember their sounds, smells, locations, etc. for five or six years, or even ten years, or a lifetime, and when they are fully mature, they will return there to lay eggs. From this point of view, their memory is still very strong, and in essence, their nervous system is not qualitatively different from ours, so the memory should only be a quantitative difference.

3) Ornamental fish to the newcomer's territorial awareness: take the most common ornamental fish - parrot fish, for example, the territorial awareness is very strong, once a well-adapted group artificially joins the new fish, whether it is the same or different kind, the parrot fish will carry out a strong attack on the newcomer, and the former partner is very friendly.

I once did an experiment in which a relatively strong parrot fish was artificially raised separately, and then the newly entered fish and its former partner were selected to be put into the space of the parrot fish. As a result of the experiment, the parrot fish did not react much to its old friend, and everything was normal. As for the newly entered fish, it used 200% of its strength to attack it, and the splash was very high, which shows the crazy procedure of its attack, and it will not stop until it dies.

Therefore, this experiment tells us that the memory of fish is actually very strong, and it can distinguish the difference between fish and between people, and the memory is deep and long-lasting. "The memory of a fish is only 7 seconds" is a saying let the writer enjoy it, for us fish lovers, we must understand this real fact - fish, will remember you. So take care of your fish with love.

The seven-second new concept portfolio has been mentioned, and there is also a seven-second memory post for fish, and you can check it out.

This is a literary parlance. The scientific argument should be that different fish should have different IQs, and the 7-second statement is not credible, for example, our fish are more intelligent and can know the people who feed them regularly, but they do not respond to strangers.

7 seconds.

I don't know why, the saying that "fish only have 7 seconds of memory" is widely circulated, but almost all research on fish memory tells us that fish have much more memory than 7 seconds. On the Internet, there is a passage that has been widely circulated: "A long time ago, someone told me:

The fish only remembers for 7 seconds, and after 7 seconds it will not remember what was before, and everything will be a new beginning.

Expansion:

However, there are also many people who take it as a scientific fact. In many Q&As, there are questions asking if this passage is scientific. In fact, if the "fish memory has 7 seconds" is taken as a scientific conclusion, many questions will arise.

Fortunately, fishes have a rather unique evolutionary position as an early species of vertebrates, so there is a lot of scientific research on fish memory.

Paradise Fish — also has a strong memory. 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 each other is an old acquaintance and lose interest in exploring.

Experiments have found that such memory can be maintained for at least 3 months.

Different species of fish have different memory, and the influence of environment, air current, and temperature will also make the memory of fish different, but according to current research, no matter what kind of fish, the memory can be maintained for at least five months, no matter what kind of fish.

People often describe the memory of forgetting the goldfish when they turn their heads, and many film and television literary works are either romantic or sad to use the 7-second memory of the goldfish to describe people or things, and there are film and television works with this theme.

Although fish are not as intelligent as humans, they are not so easy to forget. And human beings also have a forgetting curve, if they are not impressed, and they are not reviewed afterwards, it is easy to forget. In terms of memory, fish are on par with, if not better than, the "higher" vertebrates.

Fish memory experiment

The researchers conducted an experiment on fish for a month, where they deliberately trained them to respond to underwater bells and then released them back into the sea. Five months later, scientists used the same bell to swap back to the fish, suggesting that the fish could remember the bell for at least five months, not just a few seconds.

In addition, memory studies were conducted on this unique group of goldfish, and after three months of training, goldfish learned to put the lever to eat, and then controlled the joystick to work for one hour a day. After a few futile attempts to tempt the joystick, the goldfish have reduced the frequency of their attempts at the joystick, but surprisingly they will come near the joystick during their daily feeding time.

Legend has it that the memory of the fish is only 7 seconds, and after 7 seconds, it does not remember the past, so it does not feel bored in the small fish tank, because after 7 seconds, every inch of the place where it swims becomes a new world. It keeps reincarnating for these 7 seconds, not to forget, but to remember. This is an excerpt from Xu Zhimo's poetry collection describing love.

Over time, many people mistakenly believe that the memory of the fish is really only seven seconds, and many people believe it. But in reality, there is no study that shows that fish have memories of only seven seconds.

Memories of the fish. As the oldest vertebrates, fish are of great interest to scientists. Scientists have studied various aspects of fish, and many of them have been on fish memory.

Although the types of fish used as experimental materials are different, and the methods and specific purposes of the experiments are different, almost all studies on fish memory show that fish memory is much longer than 7 seconds. After many experiments, scientists have found that fish have a very strong memory, any kind of fish has a memory of more than 7 seconds, at least 3 days, and most of the fish can remember the past 1 to 3 months.

Fish research.

Fish have memories that go far beyond a few seconds, and fish are likely to have memories that can last for a year to several years.

Picher, a ichthyologist at Columbia University, once described an experiment in his book "Fish Cognition and Behavior" in which two different-colored tubes were implanted in a goldfish breeding tank, and only when the goldfish chose the right color could they get food. After some training time, the colored tube is removed. A year later, when the researchers put the tubes in the pond again, the goldfish immediately chose tubes with the colors they could get their food in.

Piccher's experiments suggest that fish are likely to have memories that can last for a year to several years. Considering that most fish have a lifespan of only a few years, their memories are quite long-lasting.

The memory of the fish is only 7 seconds".

The memory of the fish is only 7 seconds", this sentence ** is excerpted from Xu Zhimo's poetry collection. Xu Zhimo's poetry collection Split Friends wrote: "The stars and the moon sink into the wheel, never down, the memories continue to search for the same shots, and the reality switches to different emotional outlets."

Legend has it that the memory of the fish is only 7 seconds, and after 7 seconds, Yuan Li will not remember the past, so it will not feel bored in the small fish tank, because after 7 seconds, every inch of the place where it swims becomes a new world ......This is actually an excerpt from a collection of descriptions of love. Over time, it has been passed around, and many people mistakenly think that the memory of the fish is really only seven seconds, which is actually not scientific.

Experiments have shown that fish have memories that are much more than 7 seconds.

There are rumors on the Internet that the fish only has a memory of 7 seconds, and after 7 seconds it does not remember the past, and everything becomes new, so it will never get bored in that small bathtub, because once the 7 seconds pass, every place it swims through becomes a new world. But in fact, fish are more intelligent than people think.

According to Xinhuanet, in 1965, researchers at the University of Michigan in the United States specially selected a long fish tank in order 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.

Fish can remember things for about 1 month.

The memory of the fish is only 7 seconds, which is not based on scientific evidence, in fact, the memory of things can reach about 1 month, and the fish can remember for a longer time with continuous training. The fish has a short grasp of an object, but after many contacts, it can make it remember repeatedly.

As an early species of vertebrates, fish have a rather unique "status" in evolutionary history. Many scientists have studied the memory of fish, although the types of fish used as experimental materials are not the same, the experimental methods and specific purposes are also different, but almost all the research on fish memory has shown that fish memory is much more than 7 seconds.

Scientists have proven that as long as the fish have undergone a period of reasonable training, the memories and habits of these goldfish will form conditioned reflexes in the segment limbs and fingers for up to a month.

Experiments on fish memory

Columbia University in the United States has done a related experiment, they found many goldfish and put them in the same tank. Pipes of different colors were placed in the tank, and the researchers only fed fish in fixed pipes of one color.

After this pattern became familiar to the goldfish, the researchers not only scattered the fish in different tanks, but also resumed their usual feeding habits. The goldfish were fed only normally, and a year later, the researchers put the fish back into the same tank. But the goldfish have memories and are able to remember the color of the pipes that the researchers fed on, and get their food underneath the pipes.
