A hooker in fishing refers to a person who uses a hook to catch fish. This method involves attaching bait to a hook and casting it into the water, waiting for fish to bite. Hookers can use various types of hooks, including circle hooks and treble hooks, depending on the species they are targeting. In addition to traditional fishing, the term "hooker" can also refer to a specific fishing technique called hook and line fishing. This method is popular among recreational anglers and is often seen as a sustainable way to catch fish, as it allows for selective harvesting and reduces bycatch.
