2, the ground cage, also known as the ground cage net, the ground cage king, etc. Handmade cage nets are suitable for rivers, lakes, ponds, reservoirs, streams, shallow waters and so on. Mainly used for fishing small fish, lobsters, eels, loaches, crabs and other fish.
3. The floor cages are made of plastic fibers, all of which are hand-woven and knotted. Divided into one gear, the normal gear is about 50CM and the small gear is about 20CM. There are many entrances on both sides of the cage, and the internal structure is complex (called "inverted beard" in the industry). It is difficult for fish and shrimp to come out after going in. The outlet is always in the middle and tail of the cage, one on each side, or directly at both ends (this design is inconvenient, the cage is unstable, and it is easy to tilt underwater). Only one end of the cage has an exit.
There are two ways to release the cage. The big one is fixed, and the other one is put on the boat and slowly moves outward. Be careful not to put the cage too tightly. If it is too tight, you can't catch fish or shrimp. The other kind of small head is tied with a strong rope, standing at the water's edge, throwing it directly into the water and tying it to a fixed object on the shore. This is also called throwing a cage.
5. Generally, a large number of cages are put into the water at a time. There is a thin knot here, so be sure to pay attention. The air holes on both sides must find a bamboo to insert into the water and fix it above the water level (this is to let the fish and shrimp breathe oxygen and die without ability). The next morning, "go directly to the exits at both ends of the bag", and you don't have to fish it all out. Very troublesome. If you throw a cage, just carry water directly.
6. Ground cages are mostly suitable for farms, individual fish ponds, shallow water areas of reservoirs, streams or lakes and other waters with slow water flow.
