Chapter 383 Memory Only 7 Seconds

"Crayfish."

Li Xiang said from the side: "There are still a lot of crayfish in our reservoir, and I don't know where they came from. No one cares about them, so I breed a lot. I used to go home when I was idle. I have caught prawns here, and the crayfish here are very big, and if I don’t catch them for a while, they will breed a lot, and I can’t finish them.”

Little Tutu asked curiously: "Since there are crayfish here, why haven't I seen anyone fishing? The cheapest crayfish seems to cost 31 catties, right?"

Li Xiang shrugged his shoulders: "Yes, crayfish are quite expensive, but the young people in our village have gone out to work outside, and the old people don't like to eat this food, so no one usually comes here to fish for shrimp. I occasionally come back to fish Last time, I could harvest more than ten catties casually."

"so much?"

Little Tutu happily said: "Then what are you waiting for, let's go fishing for lobsters."

Yu Yishan originally wanted to remind her that this crayfish was also raised in the reservoir, and it also thrived on eating pig dung...

But after hesitating for a while, Yu Yishan still didn't say anything.

As a human being, sometimes it is better to pretend to be confused.

Carry the broken plastic bucket, which can be used to hold shrimps, and then use the internal organs of those chickens and ducks as bait, and tie them with fishing lines. The three of them each share one, and then Li Xiang leads the way. Half a circle around.

The other side of the reservoir is relatively low-lying, it is between two hillsides, and it is quite close to the foot of the mountain.

There is a half-meter-wide small water channel leading to the farmland and ditches at the foot of the mountain. The ditches seem to be formed naturally, or were excavated manually many years ago. The sides of the ditches are covered with grass. If you don’t look carefully If it is, the existence of the ditch will not be found.

Li Xiangdao: "There are the most crayfish here, they like to stay on the shore here, and in this small ditch, and sometimes climb into the grass above - then it will almost flood .”

The little rabbit squatted by the ditch to search for a while, but found no shadow of the crayfish, so it walked to the reservoir again.

"There are still fish in this reservoir, isn't the owner afraid that the fish will run away from the ditch?"

"No, you can see that there is a layer of barbed wire blocking the water mouth. Fish can't get through it, but crayfish can crawl across from the shore."

Li Xiang pointed to the water outlet of the reservoir and explained: "The water level here is not high, and the water bank is not high. Even if there is a heavy rain, it will not be flooded. The water overflowing the water level will soon flow into the ditch below the mountain. went."

At this time, Yu Yishan had already thrown the fishing line tied with bait into the water. There were many aquatic plants in the shallow water here, and the water in the reservoir was not clear, so it was not clear whether there were crayfish under the water. .

Netizens commented: "This place doesn't seem to have crayfish either."

"I heard that crayfish like to stay in the smelly ditch. The dirtier the water, the more they will reproduce."

"Impossible, we have crayfish farming here, the water is quite clean, and the output is only a lot more than these wild ones."

"It can only be said that the quality of the water has no effect on the survival and reproduction of crayfish. Their vitality is still quite tenacious."

"It mainly depends on the source of the food. As long as there is enough food, the crayfish will definitely grow crazy."

"Look! Master Shan has already caught crayfish!"

Amidst the comments from netizens, Yu Yishan had already achieved something. The fishing line he picked up unexpectedly caught three crayfish.

These crayfish stretched out their big pincers one after another, gripping the bait on the fishing line firmly, and refused to let go.

Even if Yu Yishan picked them up, they still refused to let go of the bait. Yu Yishan could only shake the fishing line a few times, and shook the crayfish that died for birds into the plastic bucket inside.

Little Tutu didn't know how to evaluate it anymore, she looked at the crayfish in the bucket and said: "These crayfish are too stupid, let alone being caught so easily, and they don't know how to let go even if they are being carried. It's like you don't have a brain at all."

"Don't expect these animals to have any intelligence. They just survive by instinct, and they have thick carapaces. Except for humans, basically no other animals are interested in their meat. They can be regarded as having no natural enemies."

Yu Yishan said: "So, when they encounter any situation, they just need to stretch out their big pliers and grab it forward. For them, there is only a difference between whether they can eat or not..."

Little Tutu nodded and said, "That's why they're so stupid... I heard that the memory of fish is only 7 seconds? The memory of crayfish probably doesn't even last a second?"

"How long is the memory of crayfish? I haven't done experiments, and I don't know much about it, but someone has done research on the memory of fish and confirmed it."

Yu Yishan said: "The so-called fish's memory is only 7 seconds. This is pure nonsense. I don't know who is so boring to fabricate such meaningless rumors."

"rumor?"

Netizens became curious: "Many people seem to say that, and those who talk about life insights even quoted this one."

Yu Yishan said helplessly: "Is it a rumor? Just think about it and you'll know. Go to the fish ponds in the park and have a look. As long as someone approaches, those fish will flock to them, waiting for humans to feed them. Feed them... If they don't have memory, how do they know that humans are here to feed them?"

"Yup!"

Netizens suddenly realized: "Such a simple truth... I never thought about it."

"No problem, no memory, the fish will not respond to feeding, and even be so idiotic that they can't take care of themselves."

"I have been lied to for so long, and I haven't thought about the truth of this rumor. Now that I think about it carefully, I find that this rumor is really low-level."

"It seems that all life with a head has a memory, otherwise what's the use of the brain growing there?"

"However, I have seen those fishermen. The fish they caught were released again, but the released fish would still bite the hook next time. It seems that they don't have a long memory at all. Where did their memories go?"

"Eh? Yeah, why do these fish sometimes act like they have no memory."

Yu Yishan said with a smile: "It's not that there is no memory, but that there is no brain. Human beings sometimes make the same mistakes, let alone fish without any IQ, unless you catch it dozens or hundreds of times a day and let it Impressed, it is possible to make it give up biting the hook."

"Isn't that a conditioned reflex?"

"Yes, conditioned reflex is also a kind of memory, and it needs to be remembered by the brain. The thinking and analysis ability of animals is much lower than that of humans, especially animals with underdeveloped brains, which can only be remembered through conditioned reflexes. to solve the problem."
