The Department of Fisheries in Bangladesh secured global recognition for ilish fish as a Geographical Indication (GI) product in August 2017, following an application made in November 2016. Ilish, belonging to the genus Tenualosa ilisha, is characterized by its torpedo-shaped silver body, with immature specimens displaying lined spots. It takes approximately eight months to a year for ilish to mature, growing up to 63 centimeters in length and weighing up to three to three and a half kilograms. The Padma and Meghna river basins, along with coastal and marine waters, serve as prime ilish production areas, contributing significantly to the country's blue economy. Various conservation efforts, including the establishment of ilish sanctuaries, have led to increased ilish availability, particularly in regions like the lower Padma River. With Bangladesh producing 75% of the world's ilish, the fish accounts for 1.15% of the country's GDP and generates substantial foreign exchange through exports, contributing to the livelihoods of approximately 20-25 lakh people involved in various aspects of the ilish industry.
