Research progress and prospect of integrated rice-fish coculture

Integrated rice-fish coculture is a green and low-carbon agricultural development model which is currently encouraged, supported, vigorously promoted and applied with an expanding production practice area in China. In the meantime, there are increasingly relevant theoretical and practical research findings, along with some new emerging technologies, modes, situations and issues. This paper reviewed the development status, key research fields and related progress of integrated rice-fish coculture in China, and analyzed the key issues and development directions to be solved urgently for scientification, standardization, smartization and industrialization of integrated rice-fish coculture at present. The prospects for the future research and industrialization of integrated rice-fish coculture were put forward in four aspects including the long-term and networking field observation researches on technologies and models of the integrated rice-fish coculture, the innovation and integration of key/supporting/interfacing technologies and optimal coculture systems, the standardization, smartization and industrialization of technologies for integrated rice-fish coculture, and the carbon/nitrogen sink enhancement, emission reduction and green and low-carbon development. This paper could provide references for better promoting relevant research of integrated rice-fish culture as well as the high-quality development of paddy eco-industry in China.
