Introduction to Outcome: Chinese mitten crab, Eriocheir sinensis, is an important species in freshwater aquaculture in China and is also a significant mainstay industry in Jiangsu province. However, an epidemic of tremor disease of E. sinensis has been a serious problem and impeded the sustainable development of aquaculture. The disease had spread to most aquaculture facilities for mitten crabs in China and the prevalence was 30 %, mortality rate was as high as 70%-100%. So the disease was listed in the list of animal epidemic diseases by Ministry of Agriculture of the People’s Republic of China (MOA). After 15 years explore and research, Prof. Wen Wang’s research group confirmed the disease infectious agent, Spiroplasma eriocheiris, which is a novel pathogen in aquaculture and was first found in crustaceans. This gives rise to extensive attention of domestic and overseas colleagues. Prof. Wang was newly selected as an executive director of Asian Organization for Mycoplasmology (AOM). With the projects from nation and province, the research group has established a systematic research system from fundamental research to core technology as well as to application around the finding of the novel pathogen S. eriocheiris. A series of original achievements have been obtained. More than 40 research papers have been published in SCI journals and 1/2 of those are SCI-Top ranking in the top 10% in the same research field. Five National Invention Patents has been authorized and one National Standards was formulated. They have set up a rapid diagnosis and techniques for prevention and control of the disease caused by spiroplasma pathogen. These techniques have been used in Nanjing, Baoying, Gaoyou, Jurong, Xinghua, Changzhou and Sihong in Jiangsu province, and also been used in some areas of Anhui, Hubei, Shandong and Guangzhou provinces. The morbidity of the disease has been reduced to lower than 3%. The model and application areas have reached in 120 million mou and generalized radiately into 200 million mou, which has contributed outstandingly to Jiangsu aquaculture and also contributed positively to promote sustainable development of Chinese aquaculture and as well as to facilitate territorial economy. The results above have been awarded by The Ministry of Agriculture of the People’s Republic of China (MOA) as Second prize of Chinese agricultural science and technology. The awards are comprehensiveness scientific and technical prizes for the whole national agriculture which is a permanent commend program of MOA for awarding the collectivities and persons who are protrude in promoting scientific and technological progress and innovation in agriculture.
