The first year of putting the guiding principles of the 19th CPC National Congress fully into effect and implementing the rural revitalization strategy was 2018. Moreover， 2018 was also a crucial year for securing clear success in building a moderately prosperous society in all respects， and a year of realizing the goal of the 13th Five-Year Plan.
　　Focusing on the goal of \"upgrading quality & improving efficiency， reducing quantity & increasing income， promoting green development and benefiting the fishermen\"， the various fishery and aquaculture agencies have led the nationwide aquatic animal prevention and control system through problem solving and by using a question-oriented approach， resulting in remarkable progress in aquatic animal health. The use of Quarantine of Juveniles in the Original Hatchery was expanded to six provinces （or municipalities），including Jiangsu Province and Tianjin Municipality. Official fish veterinarian teams were gradually developed and the quarantine system continues to be optimized. The number of epidemiological categories within the National Aquatic Animal Disease Mon，itoring and Surveillance Programme was further increased. With the implementation of national surveillance， early warning systems and risk assessment， we enhanced the capacity of our emergency response for epidemic outbreaks of aquatic animal diseases. With the step-wise implementation of the Nation，wide Capacity Building Plan for the Improvemen，t of Animal an，d Plant Protection， （2017-2025） project， aquatic animal disease prevention and control systems were characterized by coordination， implementation and consolidation. Inter-departmental and inter-disciplinary cooperation mechanisms among companies， universities， research institutes，extension stations （for disease control） and border agencies have also been established， continuously enhancing the capacity for disease prevention and control. Also， the Report of Aquatic Animal and Plant Diseases， the promotion and application of the National Distance Diagnosis of Aquatic Animal Disease Network （www.adds.org.cn）， and an improvement in disease prevention and control services have been achieved.
　　In 2018， the total output of fishery products was 64.6 million tons， of which aquaculture products accounted for 49.9 million tons，
　　amounting to 77.3% of the total. Aquaculture production of seawater and freshwater species were 20.3 and 29，6 million tons， accounting for 40.7% and 59.3% of aquaculture production， respectively. These percentages were comparable with those of 2017.
　　In 2019， ten ministries under the State Council jointly issued the report： Opinions on Accelerating the Promotion of Environm，entally-Sustainable Development of Aquaculture. The challenge and responsibility for aquatic animal health protection are higher than ever. The aquatic animal disease prevention system must continue to improve in order to cope with constantly changing circumstances；this will be critical to ensure environmentally sustainable development of aquaculture in China.
