Fishing gear can be divided into four types according to its structural characteristics and working principle.
① net gear
Aquatic products caught with nets account for more than 80% of the total catch in the world. The net consists of net, rope, float and sinker. According to the different fishing objects and working methods, fishing gear can be divided into nine categories: gill net, purse seine, trawl, open net, large net, laying net, copying net, cover net and trap.
② Fishing gear
It usually consists of hooks, baits and fishing lines. Some are equipped with floats, sinkers, fishing rods or other accessories. A fishhook is a part that is tied to a fishing line and plays the role of a hook. There are two kinds of inverted tooth structure and non-inverted tooth structure. The choice of bait is often the key to the success or failure of fishing, which can be divided into real bait and simulated bait. True bait can be divided into animal bait and plant bait according to different sources. Marine fishing generally uses animal bait such as fish, cephalopods and crustaceans; Earthworms and insects are mainly used for freshwater. Plant bait is used to trap freshwater fish, mainly rice, wheat, sweet potato and other products. The bait is made of feathers, cloth, rubber, wood, metal and plastic. Disguised as the favorite animal bait of the fishing object, or made into other bait enough to stimulate the predation reaction of the fish.
(3) rake and thorns

The former rakes up with sharp claws and catches potential catches at the bottom of sediments; The latter includes fish darts, gun saws, long-handled hooks, empty hooks and other projectors. When working, they aim at the captured object and shoot it into the body to capture it, or capture it with the spikes of empty hooks.
④ Cages and kettles
Taking advantage of the habit that some fishing objects like to dig holes, cages, cans and conch shells with small holes are set up in the waters where they often inhabit and stay to lure them to sneak in and catch them. Such as eel cages, shrimp cages and conch cages.
