Aquatic animal health and welfare are of great importance to the World Organisation for Animal Health (WOAH), particularly in the context of our Aquatic Animal Health Strategy launched in May 2021. Therefore, WOAH produces this regular aquatic animal health situation report highlighting information on disease events reported by countries and territories through the World Animal Health Information System (WAHIS) and antimicrobial agents intended for use in aquatic animals reported by countries and territories through the Global database for ANImal antiMicrobial USE (ANIMUSE). This report is intended to be used as scientific communication material published on our website. It is produced quarterly, and each edition covers one of the four species categories of aquatic animals within the scope of WOAH’s work: amphibians, crustaceans, fish and molluscs. This report provides information on fish.
