Abstract: Rice-crayfish farming is the most extensive form of integrated farming of rice and animal aquaculture in China, and has played an important role in ensuring national food security, improving agricultural quality and efficiency, and setting an example for the development of green agriculture, as well as helping farmers increase their production and income. Based on the understanding the developmental status of the rice-crayfish industry in China, this paper analyzes the difficulties that the industry face, summarizes the industrial development of the rice-crayfish model, and puts forward suggestions for the development of green and high-quality rice-crayfish farming. Results show that the rice-crayfish industry in China is still in a period of strategic opportunity with a favorable policy environment and strong developmental momentum. Both the area and production of rice-crayfish farming are increasing steadily. Rice-crayfish farming in China is mainly located in the plains along rivers and lakes and around low hills and reservoirs. There are five main models for the development of the rice-crayfish industry in China, including the developmental model of the entire industrial chain of crayfish, the model applied to "Shuangshui Shuanglü", the model of the industrial chain of rice produced by the rice-crayfish farming, the industry integration model for crayfish, and the model involving the ecological planting and breeding of both rice and crayfish without annular culturing channels. However, there are also some problems. For example, the development of the rice and crayfish industries is not synergistic, theoretical and technological innovation cannot keep up with the speed with which rice-crayfish farming is developing, the rice-crayfish industry requires further improvement, and measures surrounding policy guarantees require an urgent improvement. In order to promote both green and high-quality developmental strategies for the transformation of the rice-crayfish industry in China, this paper suggests: guiding the standardized and coordinated development of the industry using scientific planning, advancing the transformation and upgrading of the rice-crayfish industry with scientific and technological innovation, leading to high-quality development with the integration of these industries to promote rural revitalization, and improving policies to ensure the sustainable and healthy development of the rice-crayfish industry.
