Is there a limit to the number of meters in the fish pond?

If the pole length is limited to 30 meters, in fact, it is also possible to limit the pole length to 6.3 meters, because now the pole line is used. Even if some people play rogue fishing, they use long lines and short poles. The line is at most one meter longer than the pole, because if it is longer, it will be difficult to throw the pole. In this case, if the water depth is thrown, it can reach the position of 12 meters at most, and it can reach five or six meters between the two sides. As for water quality, there are many black pits that have been played. I've never seen anyone test the water quality. They all release water first, and then catch fish for people to catch.
