Circle hook: A fishing hook that has the point sharply curved back to the shank to form a circular shape. The curve shape causes the hook to catch in the corner of the fish’s mouth a large percentage of the time. Do not set these hooks; keep the line tight and reel the fish in. Circle hooks are recommended whenever using natural bait for any fishing. Some fisheries require this hook when using natural bait. Check regulations.
“J” hook: A fishing hook that has the point parallel to the shank and looks like the letter “J.” The hook has to be set with a quick yank. “J” hooks are available with different lengths and bends in the shank for different types of fishing.
Kahle hook: This hook looks similar to a circle hook, but there is a subtle difference in shape. In kahle hooks, the point is pointed toward the hook eye instead of toward the shank of the hook. The distance is also much greater between the point and the shaft.
Worm hook: A “J” hook with a 90 degree bend or notch at the top of the hook that aids in keeping plastic baits on the hook. Rarely used in saltwater fishing.
Treble hook: A three-pronged hook used often on artificial lures. The use of this hook with natural bait is prohibited in some fisheries. Check regulations.
There are many styles of fishing hooks. We have to make the right choice according to the fishing method we are used to and the characteristics of different fish.
