Why do goldfish have only 3 seconds of memory?

In terms of memory, fish are on par with, if not better, the "higher" vertebrates, including non-human primates.

Fish use tools to get food. Many fish emit electrical pulses to find prey, and some herbivorous fish carefully care for the ...... of the "vegetable garden".Of course, there are also fish that have to maintain those "less reliable" relationships in order to fill their stomachs: the wrasse lives by eating dead skin and parasites from other fish, and if it accidentally bites the "customer" **, the "customer" will abandon it and go to another more attentive "cleaner".

Many fish can clearly remember where their most satisfied "cleaner" is, which shows that they have an amazing spatial memory. For example, they draw maps to find shortcuts from one place to another.

The memory of the fish is only 7 seconds.

After seven seconds, it doesn't remember the past, and everything becomes new again.

This point of view is just a love story.

Goldfish actually have very long memories.

Goldfish also have memories and feelings.

If I told you that the beautiful goldfish swimming leisurely in the goldfish bowl also have memories and feelings, would you believe it?

According to the Sunday Times, veterinarians hope that goldfish owners will treat their beloved pets well, because the latest research has found that goldfish have good memories, they can feel pain and joy, and when their owners leave, they also want their owners to come back soon.

Previous studies concluded that goldfish only have a 3-second memory, but now researchers have found that goldfish have a very long memory. Raymond Lowe, a veterinarian from Australia, said: "People must think this statement is very strange, but goldfish owners and all veterinarians need to re-understand and take goldfish seriously.

At the Australian Veterinary Association conference in Hobart, Tasmania last week, Lowe presented his findings.

A study cited by Lowe was conducted by scientists in the United Kingdom, who found that at special times of the day, goldfish were able to learn to push the lever to find food. In another study, two goldfish that had fought were placed in the same tank as the other goldfish, and for a long time, the goldfish that had lost the battle did not dare to approach the winning goldfish, apparently fearing being attacked by the winning goldfish.

Rumor has it that goldfish only have 3 seconds of memory? Is this true? Foreigners personally experimented with **!

Fish have only seconds to remember is a complete fallacy, and recent Australian researchers have found that fish are more intelligent than humans think, with memory for months to years, and know how to learn, and can use deception. Xinhuanet, January 18** Many people think that fish have low intelligence and poor memory, and some people 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 Wobton, a research associate at the Institute for Land, Water and Society at Charles Sturt University, has been working on fish for many 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's a complete fallacy that fish only have a second memory," the British Daily Telegraph quoted Wabbton as saying

Over the past few years, a lot of research has been done on the learning ability and memory of fish, and we have 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, agrees with Wabbton.

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 the hiatus, Erickson came to the tank and called "fish fish" again, and the fish immediately swam to the surface and waited to be fed. Wabbton is smart enough to say that fish also have certain human-like behaviors, such as deception and falling into a trap.

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".

Because it has more water in its head.

This is not measured, but summarized based on the observation of the habits of goldfish.

The reason is basically because the goldfish doesn't know how to be hungry when it eats, as long as you feed it, it will always eat, so people think that the memory of the goldfish is only a few seconds, and they forget it when they just eat it, so there are not a few novices who raise goldfish and are killed to death.

I've heard that a goldfish's memory only lasts for two seconds, so every two seconds when I put it in the fish tank it says, "Huh?! New environment! ”

The single goldfish lives very freely in the fish tank, because it knows that sooner or later the owner will buy another goldfish for it to be its companion, but can the goldfish wait endlessly?

I've asked this question more than a hundred times, the memory of the fish is as long as his life, I am a professional domesticator and breeder of fish, they remember to eat there every day, and return to their resting place every day, very smart, you are talking about fairy tales, hope,.

It should be 7 seconds. But not necessarily, it may just refer to some specific memories, for some other specific information, the memory of fish is amazing, just like sea turtles will return to their birthplace every year, salmon or something can remember the smell around the sound, location, etc. for a lifetime, five or six years, or even more than ten years later, when they are fully mature, they will return there to lay eggs, from this point of view, their memory is still very strong, in essence, their nervous system is not qualitatively different from ours, so memory should just be a difference in quantity.

There should be a week or so. Stokes "trains" a group of goldfish to swim to a signal buoy with food, and establishes a correlation between the signal buoy and the food, causing the goldfish to have a certain memory of the two. Stokes first placed a signal buoy in the water and fed the goldfish at regular intervals each day; After each feeding, Stokes would delay by about half a minute to spray the food around the signal buoys.

After 3 weeks of observation, he found that the time it took for the goldfish to swim to the signal buoy to eat was decreasing, from 1 minute to less than 5 seconds after 3 weeks. On the basis of the initial 3-week trial, Stokes took away the signal buoys that were fed to the goldfish; Six days later, Stokes put the signal buoy back into the water again. Although the goldfish hadn't seen the buoy for almost a week, the goldfish swam to the buoy after a "hesitant" second, indicating that the goldfish had memorized the connection between the food and the buoy for at least 6 days.

My findings show that goldfish can remember information about things around them for at least about 6 days. If goldfish are forced to memorize through training, they can also prolong their memory. ”
