Kalastuskoukku

Kalastuskoukku, commonly referred to as a fish hook, is a fundamental tool used in angling to catch fish. Its primary function is to pierce the mouth of a fish, securing it to the fishing line. The basic design of a kalastuskoukku consists of a shank, a point, and a barb. The shank is the straight portion to which the fishing line is attached, often by an eyelet at one end. The point is the sharpened tip that penetrates the fish. The barb is a backward-facing projection just behind the point, designed to prevent the hook from dislodging once it has penetrated the fish.

Kalastuskoukut come in a vast array of sizes, shapes, and materials, tailored to different fishing methods, target species, and bait types. Smaller hooks are used for catching small fish, while larger, sturdier hooks are employed for bigger game fish. The material is typically steel, often coated or plated to resist corrosion. Various hook styles exist, including J-hooks, circle hooks, treble hooks, and weedless hooks, each offering specific advantages in different fishing scenarios. The choice of kalastuskoukku is a critical factor in successful fishing, influencing hook-up rates and the ability to land the fish.
