How deep can crucian carp survive in water?

Since we are avoiding electric fish, it has little to do with water depth. 1. No matter how deep the water is, it can’t electrocute much, because when his boat comes, the fish will avoid it, so the electric grass is basically used to electrocute the fish. 2. When the sun is bright, fish like to float on their heads. The water depth does not matter. Fish like to be under the aquatic plants, so people who use electric fish can gain a lot. 3. There is no need to hate electric fish people. It is the nature of some people to be selfish and greedy for gain. Therefore, there must be legal, moral and other means to restrain the behavior of some people. The inaction of law enforcement agencies is the fundamental reason. No one in our neighboring area dares to electrofish. The first time someone is caught, the tool will be confiscated, and the next time someone is caught, they will be fined 5,000. After a few years, no one is electrofishing anymore. []
