The VeriFish Calendar is an educational media product developed within the Horizon Europe VeriFish project to support accessible communication on seafood, nutrition, and sustainability. Designed for consumers, families, schools, educators, and seafood communicators, the calendar presents twelve seafood species through a combination of species information, nutritional highlights, recipe ideas, and sustainability-related explanations. Each monthly page introduces one seafood species and provides concise educational content intended to make seafood choices more understandable and evidence-informed. The calendar links seafood consumption not only to taste and cooking, but also to nutrition, origin, production systems, fisheries management, aquaculture practices, and environmental considerations. The calendar is designed without year-specific weekdays or fixed calendar dates, allowing it to be reused across multiple years as a long-term educational and outreach resource. This format supports continued use in classrooms, public awareness campaigns, consumer communication activities, and seafood-related events. The information included in the calendar is sourced from the FAO Global Record of Stocks and Fisheries (GRSF) and EuroFIR FoodEXplorer, which includes more than 40 national food composition datasets. The calendar’s data are current up to April 2026. This resource forms part of the VeriFish media products developed to translate verifiable seafood indicators into accessible communication tools for citizens and wider stakeholder communities.
