Fishing in an area already used by someone

Q 1: We live in an emirate on the sea coast. Some fishermen purchase old cars and tires and throw them in specific areas in the sea so that fish may gather. After that they fish and prevent other fishermen from fishing in that area.Is it permissible for other fishermen to fish in the places where those fishermen have placed these cars and tires? It should be noted that many people say that the sea belongs to Allah Alone and it is not permissible for any fisherman to prevent other people from fishing in a specific place.

A: If the person throws a fishing net or anything in the sea to catch fish, it will not be permissible for other fishermen to fish in this place except after asking for permission according to the saying of the Prophet (peace be upon him), If anyone reaches something which has not been approached before by any Muslim, they will have a better right to it.
