2. The ground cage, also known as the ground cage net and the ground cage king, is suitable for rivers, lakes, ponds, reservoirs, streams and shallow waters, and mainly catches 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 entering the cage. The water outlet is always in the middle and tail of the cage, one on each side, or directly at both ends (this design is inconvenient, and the cage is unstable underwater and easy to tilt). Only one end of the cage has an exit.
