A vendor sells hilsha fish at Kawranbazar in Dhaka October 3, 2011. From time immemorial, Bangladeshis have been passionate about hilsha fish, a strongly flavoured, white-fleshed fish known for its mouthwatering smell while cooking -- and a required menu item at New Year's and other family celebrations. But the dazzling silver creature that was declared the country's national fish upon independence in 1971 now has become a much rarer sight on tables due to rising prices.
