Explanation:

Fishing refers to an activity which typically involves catching fishes for both recreational (sports or hobby) and industrial (feeding or sales) purposes. In finishing, the fishes are caught from water such as a pool, lake, river etc. through the use of fishing nets, rod and lines and fish hooks.
