A sumptuous Bengali feast is incomplete without the hilsa . But very soon Bengalis in Bangladesh might well have to do without it due to decreasing its birth rate. Hilsa is the national fish of Bangladesh. In Bangladesh, about 75 percent of the world's hilsa is extracted. When hilsa is caught in flocks, the silver color of hilsa evokes silver hope in the minds of the fishermen. I captured this picture from bank of Karnafully river in Bangladesh.
