To understand the epidemiological situation of prawn and marine fish fry in Binzhou,to man-age the potential risks,and to provide a scientific basis for the healthy and orderly development of the aquaculture industry,in 2022,a main disease monitoring of prawn and marine fish fry was carried out in Binzhou City(Wudi County,Zhanhua District and Boxing County).The detection for prawn seed-lings included white spot syndrome(WSD),infectious subcutaneous and hematopoietic tissue necrosis viral disease(IHHN),shrimp(EHP),acute hepatopancreatic necrosis disease(AHPND),shrimp iphrovirus disease(DIV-1),Taura syndrome(TS),infectious muscle necrosis disease(IMN).For marine fish fry the detection focused on viral neuronecrosis disease(VNN).65 samples of Penaeus vannamei were detected for 8 kinds of prawn pathogens,a total of 5 pathogen positive samples were detected,and 2 or even 3 kinds of pathogens were found in the same sample.It is suggested that in the process of introducing,breeding and raising of prawn seedlings,multiple pathogens detection should be carried out,so as to control the quality of seedling from the source,ensure the health of prawn and promote the development of prawn breeding industry.
