Hilsa is a popular fish found in the rivers and coastal waters of South Asia, particularly in Bangladesh, India, and Pakistan. Known for its rich flavor and tender texture, it is a staple in many regional cuisines. The fish is often prepared in various ways, including steaming, frying, and in curries. Hilsa is also significant for its cultural importance, especially in Bengali traditions, where it is celebrated during festivals and special occasions. The fish migrates from the sea to freshwater rivers for spawning, making it a seasonal delicacy that many people eagerly anticipate each year.
