Fishing hooks are small, pointed tools used in angling to catch fish. They are typically made of metal and come in various shapes and sizes, designed to hold bait and secure fish once they bite. The sharp point of the hook penetrates the fish's mouth, allowing anglers to reel in their catch. There are different types of fishing hooks, including J-hooks, circle hooks, and treble hooks, each serving specific purposes. The choice of hook depends on the type of fish being targeted and the fishing technique used. Proper hook selection is essential for successful fishing and minimizing harm to the fish.
