Currently, fishing gear factory net cage of finished fish species is generally 1.5cm, requirements into the box about 6.7cm fish species. Most fish farmers are using ponds or paddy fields, and then reared in fish cage breeding, so fish into the box about the end of June to early July. Due to various reasons, it is very hard for many fish farmers to breed grass carp seagrass to 6.7 cm in two months, thereby delaying the entry of fish species into the tank. If the use of self-made small cages to cultivate grass carp species can be a good solution to this problem, the specific practices are: 1. Production of small cages. Selection of screens made of plastic gauze, cages by the style of making a small cage, the area
