National Fish Day, or Hari Ikan Nasional, is observed in Indonesia every November 21. Established by a presidential decree in 2014, this day highlights the significance of fish and aquaculture in the country's economy and food security. The celebration coincides with World Fisheries Day and is coordinated by the Ministry of Maritime Affairs and Fisheries. Activities typically include exhibitions, workshops, cooking demonstrations, seafood tastings, and environmental initiatives such as coastal cleanups. Indonesia, being an archipelago with extensive coastlines, plays a crucial role in global fisheries, ranking as the third-largest producer of fish and aquaculture. The day also aims to promote sustainable fishing practices and recognizes the importance of fish as a high-protein food source.
