To say that it is anchored means that you caught a fish when you didn't take the initiative to bite the hook, and accidentally pulled the hook back and hung it up. Fishing on weekdays, with ordinary hooks, plus fish favorite bait (artificial or natural, such as earthworms). When the fish swallow the bait, they swallow the hook in their mouth and then get out of the water. This is called fishing. The hook used to anchor fish is not an ordinary hook, but an anchor hook that sinks into the water when a big ship is moored. Of course, it has the same shape as the sight of the ship and the same size as the hook. Instead of hanging bait on the hook, the anchor hook quickly paddles through the fish in the water, so that the anchor hook hangs on a certain part of the fish's body and drags it ashore. This kind of anchor hook will do great harm to fish. It will break down less and hurt more fish. Some fish that escape by scratching will soon die. Therefore, in order to protect fish resources, even fishing should be civilized.
