Fish are not as cute and fun as dogs, so they can't get as much sympathy from people as dogs. Second, fish can't bark like dogs, so they can't tell people if they're in pain. We scream when we accidentally hit the body, which is a conditioned reflex caused by pain.
When a pig is killed, the pig is called heart-splitting, and even the pain is fear. So, do fish feel pain? This is a deceptively simple question, but in reality it is very complicated, since even if the fish are opened, it does not make any sound, which makes it impossible for us to tell from the surface whether they will be painful or not.
At first, the team went fishing and found that the fish had been removed from the hook and put into the water, still swimming freely without any abnormalities. Therefore, the research team believed: the fish had no pain. The fish has no pain, and when we kill the fish, the fish jumps because of the lack of oxygen.
In fact, when we buy live fish, the boss usually gives the fish the first stick before killing it, not only because such fish are honest and easy to kill, but also because a stick is equivalent to us taking anesthetics during surgery.
So it won't be so painful to kill it. Of course, fish have a more nervous system and brain than mammals.
Much simpler, which causes them to open the abdomen, as long as the respiratory system (gills) is not removed, it can still live for a while, after all, it can still get trace amounts of oxygen from the air, its circulatory system.
Remove the gills and open the abdomen, all at once.
Of course, not all fish can't call, such as the yellow duck.
Yellow catfish) can make sounds, in addition, there are more than 50 known species of calling fish, and the reason they are killed is that their calls depend on compressing the bladder to press air, and in the water environment, they cannot compress the bladder and naturally cannot make sounds. Most fish don't have a sound system, so even if they are killed, they won't make painful calls. But that doesn't mean they won't be painfulIt turns out that fish actually have pain receptors, which means they also know pain, and usually fish are killed, and the longer they hold on, the more painful they become.
-
I don't think fish feel pain; They send out a distress signal when they are killed, and they have their own ability to communicate, and they will warn their companions by waging their tails vigorously.
-
I think fish can also feel pain, although their brains are relatively simple, but their nerves are still very developed and can feel pain; When the fish is killed, the fish will be knocked out first, and then the shark will be carried out, so the fish generally do not send a distress signal when they die.
-
Fish do not feel pain, and when they are killed, they are out of their original living environment and do not feel pain; Sending out some distress signals, their bodies will tremble, but not violently.

The fish does not hurt when you kill the fish. A recent study concluded that fish lack the necessary pain receptors in their brains to experience pain in the same way that humans and other animals do. Although fish possess nociceptors, these sensory receptors are able to respond to objects or events that harm their bodies by sending warning signals to their brains.
According to the authors of the study, the function of these receptors in fish is not the same as in humans.
"Even if fish were conscious, there is no evidence that they have the same pain sensations as humans," the study's authors wrote in a study synopsis. The researchers claim that a nociceptor called a C-fiber nociceptor in humans is the main cause of pain in humans, but this receptor is rare in finfish and is found in sharks and rays.
It doesn't exist in the body. The researchers wrote that another A-triangle nociceptor triggers another simple reflex escape that is fundamentally different from real pain.

According to scientists, fish do not have a cerebral cortex that can understand pain, which means that it does not have a sense of pain. So why does he writhe when we swing a knife at him? For example, after local anesthesia, a person is in a state similar to a fish, it has an ordinary tactile sensation, but it doesn't feel pain, but we will dodge when we see something dangerous, which is the consciousness at work, but it doesn't feel pain.
It's just like "Oh, he's cut me, I'm going to take the dog."

Killing it is to kill it, the pain is certain, but it can't do anything, people are swordsman, I am fish and meat, and I can't change it, so I can only let people slaughter it.
-
Definitely, animals are sentient, and they are struggling when they keep writhing their bodies.
-
Yes, so in the future, you should kill the fish to reduce its pain.
-
Definitely, it's like taking a big knife to peel off your body, you imagine it for yourself.
-
Yes, because they are spiritual!
-
It's so cruel that the touch of the fish is well developed.
-
When a fish is caught, do you really feel "pain"? Hear what the scientists have to say!
-
Give you a knife and you won't be in pain.
-
Fish are living creatures, and life naturally hurts.
-
Fish have painful nerves and scream when they are killed, but the frequency of their voices is not the same frequency as ours, and we can't hear them, so it seems that they don't scream when they are killed.
-
Fish cannot make sounds without vocal cords, and the nervous system in fish is not very developed, and they cannot transmit pain information to the brain.
-
Yes, the fish also scream, but we can't hear it, because when we kill the fish, the fish are also jumping around.
-
Some time ago, I saw on CCTV4 that a professor of fisheries at the Chinese Academy of Sciences said that fish have not evolved to the point of having pain nerves.
-
Of course, the basic functionality is total.
-
Fish do not have pain nerves, for example, when fishing for crucian carp, if you stab the fish gently and quickly, the fish will not struggle, but the fish will spit out a foreign object in its mouth out of instinct.
-
Fish have non-painful nerves, so they don't feel pain.
-
Do fish feel pain? Most people think that cold-blooded repatriated animals like fish-type Zen animals are painless and hungry.
Yes, all animals with nerves have, pain.
