1. Port culture is a traditional cultural model in China, with a cultural area ranging from a dozen hectares to several hundred hectares. Generally, it is surrounded by dams according to the natural topography of the intertidal zone in the sea area, and the breeding equipment is simple. In aquaculture, seedlings are generally harvested naturally and workers are allowed in, but there is no fertilization and no bait, and the products are completely provided by natural productivity. Its products include fish, crab, shrimp and shellfish. Artificial seedling varieties can also yield more than ten kilograms per mu, and the comprehensive benefit can reach several hundred yuan. Port culture is a cultural way worth promoting and developing. Especially in recent years, the serious outbreak of shrimp disease and the serious eutrophication of coastal water bodies show the great advantages of this method. 2. Semi-intensive farming is developed on the basis of port farming. That is to build an ecological environment suitable for the survival and growth of prawns, so that prawns can obtain higher yield per unit area. The establishment of ecological environment includes the artificial control of water temperature, salinity, transparency, sediment, water depth and harmful organisms, so that it is in the most suitable environment needed by prawns, and then through reasonable seedling release and feeding, higher yield can be obtained. This method can achieve high economic benefits and little adverse impact on the environment because of less bait and less organic matter in shrimp wastewater. Therefore, it is also a breeding method worth popularizing. 3. Intensive farming mode This farming mode is generally adopted in small ponds. Such shrimp culture requires good pond conditions, high water exchange rate, complete aerobic equipment and facilities, mainly artificial high-quality bait. As long as the environment is controlled reasonably and the feeding is reasonable, high yield can generally be obtained. The domestic intensive cultivation yield per mu is as high as 1050 kg, and the benefit is also very high. However, this method requires a lot of money, large investment, high risk, high bait coefficient and serious environmental pollution. Therefore, from the perspective of long-term interests, large-scale promotion should not be advocated. 4. Polyculture refers to other kinds of fish, shellfish, algae and crabs. Feeding with shrimp at the same time, the cultured products include shrimp and polyculture varieties. The selection of prawn polyculture varieties is harmless in principle, does not affect the survival and growth of prawns, and does not compete with prawns for food or have weak competitiveness. It's better to be omnivorous or saprophagous, and shrimp bait can be used. Through mixed culture, the utilization rate of bait can be improved, the organic pollution of shrimp wastewater can be reduced, the yield can be increased, the economic benefits can be increased, and the risks caused by diseases and failures of individual cultured shrimp can be reduced. 5. There are many other aquaculture methods, such as intensive shrimp culture, shrimp culture in net enclosure, shrimp culture in cage, etc. These farming methods are rarely used in China.
