Plastic greenhouses to nurture crabs are the technical basis of various models of crab breeding process, which is an important part of improving the product crab specifications to improve the survival rate of seedlings. The principle is based on the biological characteristics of juvenile crabs to provide a good ecological environment (aquatic plants, water temperature, food, etc.) needed for their growth and molting to achieve simultaneous improvement of ecological and economic benefits. The eco-agricultural technology model in coastal and interior shortage
