not necessarily!

Memories of their own children...
Only three seconds
Jokes are jokes, but did you think about this problem when eating fish? It is said that fish have only seven seconds of memory, why does everyone think that eating fish will become smarter?
Eating more fish does help with health, but there are some misunderstandings about people's memory of fish for only seven seconds and that eating fish makes people smarter.
Fish is not as simple as you think!
In most of our minds, fish either swim quietly in the water or lie tender on a dinner plate, from the use of tools to "social roles", fish do more than most people think.
When it comes to fish, most people outside the fishing, seafood and other industries generally believe that they have little perception, and even the memory of fish is only seven seconds. Fish have stiff faces, limbs that don't grasp, and can't make a sound when they leave the water, which are all reasons why they can easily be underestimated.
But as long as there are circles dealing with rivers, lakes and seas, there are always a few legends about fish.
They may compare fish to rivers and lakes or to demons and ghosts, and they are in awe and know what to do, which is the accumulation of thousands of years of experience of fishermen.
So, are fish really as cute and ignorant as we usually see?
In 2003, the School of Psychology at the University of Plymouth conducted an experiment on fish memory time, which proved 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 sociality of seabed fish
The result is that trained fish quickly know to push this lever at the exact time in order to get food. A series of similar studies have also demonstrated that fish can be easily trained, that they can eat food at specific times, and that they have a conditioned reflex to a sound signal.
As animal behaviorist and author Jonathan Balcomb explains in His Delightful Exploration of Fish Cognition, Emotion, and Perception, this enduring myth belies the astonishing abilities of our finned fellow fins. Tuskfish use tools, lionfish are cooperative, peacock fish are subordinate to social hierarchy, wrinkled gobies form a complex psychological map of tidal pools, and largemouth bass can recognize faces.
Clean fish boldly remove parasites from the mouths and gills of "customers," including predators like sharks. While it's easy to think of this symbiotic relationship as an evolutionary instinct, Balcombe reveals that it's closer to a learned cultural contract: Clean fish can identify more than 100 individual clients, remember when they last combed the skin for each client, and soothe irritable clients with gentle massages.
Balcombe writes, "This system encompasses long-term relationships built on trust, crime and punishment, pickiness, audience awareness, reputation."
In fact, a fish knows much more than that, each fish has a different personality, may also have different "fish raw", there are other ways to interact with these amazing animals, such as when a sumei fish takes the initiative to approach a trustworthy diver and accept his kindness.

Older people often say that eating more fish can make you smarter, and there is a certain misunderstanding here.
The intelligence mentioned here is not all equal to intelligence, what is intelligence?
It can also be interpreted as ear hearing, sight!
Fish is a "high-fat" food rich in healthy polyunsaturated fatty acids, such as the omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), and seafood such as fish, which our bodies cannot produce enough, is one of the best sources.
Therefore, eating more fish will not necessarily improve intelligence, but it will help the growth and development of children's brains and so on.
The nutritional value of fish is not low!
The British Journal of Science and the National Cancer Institute have shown long-term follow-up data on hundreds of thousands of people that regular consumption of marine fish and seafood products can help reduce the risk of disease death and improve quality of life. The secret lies in omega-3 fatty acids.
Because the DHA contained in fish and other seafood can maintain the normal function of the retina, promoting the healthy development of vision also has great benefits for human brain development.
At the same time, it is an indispensable nutrient for the growth of the nervous system, and the omega-3 fatty acids contained in seafood in addition to being very good for the human cardiovascular system, it can also enhance concentration, reduce stress and reduce the incidence of aggressive behavior in children, scholars believe that from the age of two years old can eat fish, in the later stage should eat more fish.
Fish is now one of the most important food sources for our plates, and we should be grateful for nature's gifts.
