Application value of Rice-Fish Symbiosis in Aquaculture

The superiority of paddy field fish culture is more and more recognized by people, because it is not only scientific, but also mass, and has both practical and long-term interests. A good management of 1 mu of fish rice fields with a fish yield of more than 10 kg is equal to the fish output of 2 mu of reservoirs (the current average fish output of reservoirs in the country is 5.5 kg per mu). Moreover, it provides a large number of large-scale and high-quality fish species for mechanized high-density fish production and large water surface release work. In Sichuan, Guizhou and Heilongjiang provinces, rice field fish production accounts for 8.5% of the province's total output of aquatic products, respectively, and has become one of the main ways of local aquaculture. Fish culture in rice fields plays an important role in increasing the production of freshwater fish and promoting the development of freshwater fisheries in inland rice farming areas far from the seaside and fishery centers.
