How high is the net bag hanging?

The depth of the net bag is calculated by the water inlet area and the material of the net cloth.

Hold about one-third of the net mouth with your hand, hang the net mouth on your thumb with your right hand (this is the most important thing to hook the net mouth with your thumb when casting a net), and then hold the remaining net mouth with your hand at a convenient distance.

Sprinkle it from the left side of your body with your right hand, and then send it to the left hand net. Hold the net with your right thumb and send it out at the right time. Practice a few more times and you'll learn it slowly. Its characteristic is that it will not stain clothes and can be operated in chest-deep water.

Fishing nets include trawl, purse seine, cast net, fixed net and cage. Trawl and purse seine are heavy nets for marine fishery fishing. The mesh size is 2.5 ~ 5 cm, the diameter of the net rope is about 2 mm, and the net weighs several tons or even dozens of tons. Usually a pair of tugboats are used to chase the fish separately or a canoe is used to lure the fish to gather and round up.

Cast net is a kind of optical net for fishing in rivers and lakes. The mesh size is 1 ~ 3 cm, the net rope diameter is about 0.8 mm, and the net weighs several kilograms. Fixed nets and cages are fixed nets used for artificial culture in lakes, reservoirs or bays. The size and specifications vary with the species of fish. Keep fish in certain waters to avoid running away.
