How many seconds do fish lose their memory?

Love you the way you fish for 8 seconds.

I was told that a fish only has a memory of 7 seconds, and after 7 seconds it doesn't remember the past, and everything becomes new.

So in that little fish tank it never gets bored, because after 7 seconds, every place it swims through becomes a new world. It can live forever in freshness.

I'd rather be a fish, forget everything after 7 seconds, the people I have met, the things I have done can disappear, but I am not a fish, so I can't forget the people I love, I can't forget the pain of worry, I can't forget the pain of lovesickness...

The fish can't see the ** tears of love, but they can feel the heartache of each other, in this life, none of us can be a free fish, so you can't feel the heartache of mine when you leave me. Just as I don't notice that you love me....

How long can you love someone?

If I were a fish, I could love you for 7 seconds.

7 seconds later I fell in love with you again, and I loved you like this for the rest of my life. The way with fish.

I'm blinking, how about you? Are you okay while I'm blinking? I miss you, so I keep blinking because I don't want the tears to flow.

It turns out that the fish also have times of longing, and they also feel pain. How good it is to be a fish in the water, you can freely shed tears for love, and you will not be seen and hurt.

I often ask myself, what am I losing in order to love you, it turns out that what I have lost is myself. And more importantly, I prefer to continue like this, because I don't want to live without you.

I can see the splendor of the sun now, I can see the brightness of spring, I can see your shy face. If one day, I can only see the darkness, I wish I was really a fish, because I can always face you with my eyes open without worrying about being seen by you and sad.

What do I have to choose from?

If God gives us a chance to make fish, I hope you can feel my heartache...

If God gives us a chance to make fish, I hope that I can love you for 8 seconds, because 8 seconds is a lifetime for the memory of fish...

The thief of time. So the memory of the fish is only 7 seconds or 6 seconds is just a literary statement, the writer uses this to create a beautiful legend, in fact, the memory cannot be accurately measured by seconds, and the memory of the fish is not so short, there are scientific studies that have shown that the memory of the fish is more than 7 seconds, this is a complex problem, there should be no clear answer, I hope it can help you.

It can't be just seven seconds.

Many people think that fish have low intelligence and poor memory, and some even say that "fish only have three seconds of memory". Australian researchers have found that fish are more "intelligent" than humans think, with memories that can take months or even years to remember far more than seconds, and that they also have the ability to learn and use deception to hunt.

Kevin Warbton, a research associate at the Institute of Land, Water and Society at Charles Sturt University, has been working on fish for more than 10 years, particularly freshwater fish in the south-east waters of Queensland. He said that the perception that fish only have short memories is completely wrong.

It is a complete fallacy that fish only have 3 seconds of memory," the British "Daily Telegraph" quoted Wabbton as saying on the 15th: "In the past 15 years, (our researchers) have conducted a lot of research on the learning ability and memory of fish, and found that fish are actually quite complex. ”

"Fish are able to remember the type of prey for months," he says. Once they are attacked by a predator and then know to hide from such predators, this memory can last for months. And after the carp is caught on the hook, it will avoid the hook for at least a year. ”

Myth busting Dr Ashley Ward, a fish biologist at the University of Sydney, shares Wabbton's views. He believes that the misconceptions about poor memory and mental retardation in fish may have originated from early zoological research.

"Zoologists at the time were using humans as a reference to test the abilities of fish, and of course the fish appeared incompetent," Ward said. In fact, fish have amazing memory.

For example, he said, Professor Charles Erickson in the United States fed a school of fish, each feeding called "fish fish" for several months. After a five-year hiatus, Erickson came to the tank and called "fish fish" again, and the fish immediately swam to the surface and waited to be fed.

Pretty smart Fishes also have certain human-like behaviors, such as deception and falling into a trap, Warbuton said. Fish are able to recognize other fish and adjust their behavior based on interactions with other fish.

For example, he said, two groups of Siamese fighting fish are fighting, and if one loses, the other will be attacked more violently.

The reef fish is a clean fish that feeds on parasites and slime from large fish. They know how to adapt their work attitude to the working environment. "If there's a potential 'customer fish' around, they'll perform better, which will raise the impression and attract potential 'customer fish,'" Warbuton said.

According to Wobton, fish also have the ability to learn. When he studied the freshwater fish silver perch, he found that when there was only one prey object, the silver perch became more and more efficient; However, when faced with two types of predators, the predation efficiency of the silver bass is much reduced. "We think it's because they're distracted, and it's the cost of learning," Wabbton said.

Ward also cites a species of cannonball fish in northern Australia that "use tools and other tricks to trick prey".

Fish don't have only seven seconds of memory.

In daily life, we often hear the saying that fish only have seven seconds of memory, but according to scientific experiments, fish have not only seven seconds of memory. The fish we see have a long history and are the oldest vertebrates on Earth, with almost all terrestrial vertebrates on Earth evolving from fish morphology more than 500 million years ago.

Scientists have experimented with goldfish, and studies have proved that as long as the fish have undergone a period of reasonable training, the memories and habits of these fish will form a conditioned reflex for up to a month, and some fish memories will be inherited, such as zebrafish with a long strip pattern, the memory of this fish can be retained in its own DNA and passed on to the next generation. The brains of fish are a little smaller, but people are not forgetful, which may be the reason why when you fish, people don't take the bait.

The habits of fish

Fish swim around underwater and breathe by gills for the main purpose of foraging. They belong to ectotherms, and their body temperature changes with the water temperature, and the water temperature changes in different seasons will affect the range of the fish. When the weather is hot and humid and the air pressure is low, the fish will be anorexic; When the water temperature is right and oxygen is abundant, fish will be more active and will actively forage for food.

Fish feed on small fish and shrimp, plankton, plant seeds, insects, etc.

Most fish live either in freshwater or saltwater, but less than 10% of migratory fish migrate back and forth between freshwater and marine environments. Growing in the ocean but needing to go to freshwater to breed is called anadromous migration, such as the Chinese sturgeon; It grows in freshwater but needs to go to the ocean to breed, which is called river migration, such as the flower eel Tongling. If the fattening and breeding migration occurs between rivers and lakes, it is called semi-migratory fish, which is generally fattened in lakes and spawned in rivers, such as the four large fish.

Most people think that fish only remember 7 seconds, but in fact, fish remember for only a few seconds.

In 2003, the School of Psychology at the University of Plymouth conducted an experiment on fish memory time, which showed that fish had a memory time of at least 3 months and were able to distinguish the shape, color and sound of different objects. The experimental method is to fix a lever in the water, this lever is only 1 hour a day in the water, train the fish to push this lever at this specific time, if the fish can remember this time, and can push the lever, it will get food as a reward. The result is that trained fish quickly know how to push the lever at the right time in order to get food.

A series of similar studies have also shown that fish can be easily trained, that they can eat food at specific times and have a conditioned reflex to a sound signal.

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.

Could it be that the goldfish is the god of road idiots? In fact, scientists have really used "way recognition" to test the memory of goldfish, but almost all current research on fish memory tells us that fish can remember much more than 7 seconds.

2: The first time I heard the saying that the memory of the fish is only 7 seconds, it was when I watched the Hong Kong film "The Thief of Years", the two people who were talking at that time were a pair of young children, and the girl was distressed because she felt that the fish in the fish tank could only swim back and forth in the fish tank, and then the boy said that the fish only had 7 seconds of memory, and after swimming from this end of the fish tank to that end, she had already forgotten about this head, and every time she swam there was a new feeling, so the girl was happy. Typical flirting, so I never believed it.

3: The reason why fish only have 7 seconds of memory is used as a metaphor for some unhappy things in life, and you can use 7 seconds to make those unpleasant things disappear and start a good life again, of course, this is a beautiful story.

Fishes, as an early species of vertebrates, have a rather unique evolutionary position, so there is a lot of scientific research 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.

It's a fable

In the story du "The Legend of the Fish", the fish will also have a fight on the sea.

When the first fish (scale) gets to know the first fish (fin), it will become good friends with it, and later (scales) have more and more good friends! There are more and more good friends! In the end, the battle between the fins and scales caused many fish to die, and the creation punished the fish so that the fish only had 7 seconds of memory, so that the fish would not remember friends or enemies, and naturally there would be no hatred, and there would be no more fights and wars.

The fish forgot the hatred, and the fins forgot the scales, and when they met again, the fins looked at the scales, and the scales looked at the fins, looked at each other for seven seconds, and then they swam away together. I don't know why the fins weep and the scales cry. Swim and swim and swim for a long distance, and there is a large school of fish behind it.!

Legend has it that if humans drank it and there was a war, the Creator would erase human memories like fish, leaving only seven seconds of memory. So that there will be no more wars)
