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.
