Description

technical field [0001] The invention relates to a fish feeding and fishing net cage, in particular to a floating fish feeding and fishing net cage, which belongs to the technical field of fishing nets. Background technique [0002] At present, when catching various fishes on the surface of large-scale aquaculture, traditional drag nets and trawl nets are mainly used. The rope drags all kinds of fish into the net. This traditional fishing method mainly suffers from heavy damage to the fish body during struggle, and high mortality after the fish is caught out of the water, thereby reducing its commodity value; the most important thing is Due to the work of dozens of people, when the trawling net is fishing in the water, due to the restrictions of the aquatic plants, reeds, and unevenness of the bottom bed in the water, all kinds of fish that escape from the trawling net continue to live in the water body. Without timely treatment, various fish infectious diseases will spread...
