A staff member of a crab production company works at a rice-crab commensal field in Panjin City, northeast China's Liaoning Province, July 16, 2020. Panjin City has not only China's high-quality rice production base, but north China's larger river crab artificial incubation and breeding base. The city has developed a rice-crab commensal eco-agriculture mode that river crabs are bred in growing rice. This mode has created a new method for farmers planting rice to increase incomes.
