Sport fishing is normally done with a fishing rod and line with any number of hooks to get the fish. This method is called "angling". There may be rules that say how many lines and hooks one fisherman can use and how many fish he can catch. Anglers in fresh water catch many Black Bass (Black Bass includes the entire range of Bass fish), Pike, Muskellunge, Perch, Carp, Trout, Salmon, and Sunfish. Fish people get in saltwater include Swordfish, Marlin, Tuna, and others.
