Emergency treatment and reflection of red tide event of Gymnodinium catenatum in Fujian sea area in 2017

Fujian is one of the provinces that red tide frequently occurred. During 2000 to 2017,219 red tides have been recorded,among which 35 red tides caused damage to fishery culture or the health of people. Emergency disposal of toxic red tide is very important for the safty of people's consumption,the development of marine fishery economy,and the construction of Ecological Province in Fujian. In this paper,the process of red tide events,the main emergency treatment measures,and problems were discussed,based on the red tide event of Gymnodinium catenatum in Quanzhou and Zhangzhou sea areas in 2017. During the disposal of the toxic red tide event,the government departments effectively curbed the further expansion of the situation caused by the red tide,and ensured the food safety of aquatic products by taking timely control of shellfish culture areas,adjusting the monitoring work according to the dynamic changes of red tide,opening the dynamic informations initiatively,and terminating the emergency response timely. In view of the deficiencies in the event process,such as departmental linkage and monitoring capability for red tide,etc,we wish to make the following proposals:1)The cooperative emergency response mechanism should be improved;2)The basic emergency capacity at the city level should be improved;3)New technology can be applied for toxic red tide biological monitoring;4)Make fast-detection technology for the detection of shellfish toxins highly applied to ensure the food safety of aquatic products.
