A giant Baghair fish weighing around 60kg went up for sale in Sylhet city's Lalbazar on Sunday afternoon.
The fish was netted from the River Kushiyara in Fenchuganj upazila of Sylhet district on Saturday night.
Many curious people gathered to see the rare-breed fish and take a photo of it. Mujibur Rahman, a fish trader at Lalbazar market, said he bought the giant Baghair fish from Fenchuganj in the morning.
Many customers had been urging the trader to cut the fish into pieces and sell it at a fixed per kg price.
Mujibur said, "It is less likely that someone would buy the whole fish. I would cut it into pieces on Monday if the expected price of the fish is not attained."
The trader expects to earn more than Tk1 lakh from selling the fish pieces. Earlier, per kg Baghair fish was sold for Tk2,000 to Tk2,500 in Lalbazar.
Baghair, which is available in freshwaters of Bangladesh, India, Burma, Thailand, Cambodia, Vietnam, Sumatra, Borneo and Java, is an endangered fish.
The International Union for Conservation of Nature listed the species in its Red Data as one of the "critically endangered" freshwater fishes of Bangladesh.
