Hilsa fish, commonly known as hilsa, is the national fish of Bangladesh and one of the country's most valuable seasonal food commodities. The primary global source in Bangladesh, accounting for the majority of the world's total supply, is of profound economic, cultural and ecological importance. Fish prices, river and marine catch, fishing restrictions, conservation regulations, export potential, consumer demand, fishermen's livelihoods and the broader seafood economy of Bangladesh are all factors that affect the fish's viability.
