Hilsa fish, also known as Ilish, is a popular fish found primarily in the rivers of South Asia, particularly in Bangladesh and India. It is known for its distinctive silver skin and rich, oily flesh, making it a favorite among seafood lovers. Hilsa is often cooked in various ways, including steaming, frying, and in curries. This fish migrates from the sea to freshwater rivers for spawning, which makes it a seasonal delicacy. Hilsa is not only cherished for its taste but also holds cultural significance in many regions, often featured in traditional festivals and celebrations.
