    Dr. LIU Jiankang, a world renowned fish biologist and freshwater ecologist who pioneered in both freshwater ecology and fish experimental biology in China, a member of Chinese Academy of Sciences (CAS), a former director, honorary director, and professor of Institute of Hydrobiology (IHB) of CAS, passed away peacefully at 10:00 PM, November 6, 2017 (Beijing time) in Wuhan, China. He was 100.   

    Dr. Liu was born on September 1, 1917 in Wujiang, Jiangsu Province. He obtained his bachelor degree in science from Dongwu University (former Soochow University) in 1938. During 1939-1945, he did his post-graduate study and then worked as assistant and associate professor at Institute of Zoology and Botany under Academia Sinica (former IHB). He obtained his Ph.D. from McGill University, Canada in 1947. After a brief period of stay in Canada, Dr. Liu returned to China in February 1949. Since the establishment of CAS in 1950,  Dr. Liu worked at IHB as professor until the last minute of his life. He also served as associate director, director, and then honorary director of IHB. He was the 1st director of the State Key Laboratory of Freshwater Ecology and Biotechnology (SKLFEB). Because of his outstanding work in research, Dr. Liu was elected to the prestigious CAS as a member in 1980.   

    Dr. Liu served as executive committee member of the 4th, 5th, and 6th committees of Hubei CPPCC (Chinese People’s Political Consultative Conference), vice president of the 7th committee of Hubei CPPCC, the 2nd and 3rd president of Hubei CAST (China Association for Science and Technology), President of Hubei Jiusan Society.    

    Dr. Liu made significant contributions to both fish biology and freshwater ecology. In the 1940s, he first discovered sex reversal in rice field eel (Monopterus javanensis), thus opened a fresh field of research in the mechanism of sex determination in the lower vertebrates. Since the 1950s, he practiced various new strategies based on experiences in pond and open water aquaculture and greatly helped promoting China’s freshwater fishery development.    

    Dr. Liu led the fishery resources investigation of the Yangtze River, which is the most systematic and comprehensive freshwater fishery survey in China. The obtained results provided important scientific information for assessing the ecological impacts of the Gezhou Dam and the Three Gorges Dam on the Yangtze River. He pioneered the application of the ecosystem ecology concept in studying freshwater ecology in China and led a 40-plus years East Lake ecological research, which is recognized as a key member of international community of limnology. His great discoveries had been enlisted in textbooks and his contribution to the fields has been recognized by scientists world-wide. People in his generation as well as the generations that follows regarded Dr. Liu as a master in science with innovative spirit and independent thinking. He was great in science education and inspired young scientists in many generations. The scientists and the students supervised by him are now leaders in different areas of aquatic biology in China.   

    During his tenure as IHB’s director, he set the institute’s long term research goal on freshwater ecology based on the national needs in economic development and environmental conservation.  It paved the way for establishing the SKLFEB and had deep influence on development of IHB. 

    One hundred years with a warm heart, Dr. Liu is among the most distinguished Chinese scientists. In his 70-plus years’ science career, Dr. Liu persisted in truth seeking and serving his country. He had been contributing his efforts in China’s freshwater resources utilization and sustainability until his last breath. His passing away is a great loss to IHB and the field of freshwater biology. He will always stay loved and remembered.    

    Dr. Liu is survived by his four children, his sons LIU Dixin and LIU Xianping; his daughters LIU Jun and WU Xinxing, as well as four grand-children, his grandsons LIU Yizheng and LIU Yinshan; his granddaughters HUANG Jin and CAO Miao. He is also survived by a sister LIU Jiaqi   

    Visitation will be held during November 8 and 11, 2017 at IHB. Memorial Service will be held at 8:30 AM on November 12, 2017 at Tianyuan Hall, Wuchang Funeral Service Center in Wuhan.  

    Rest in peace, Dr. Liu!
