The second-largest city, Chittagong, has the biggest wholesale market for marine and freshwater fish. This place is known as Chattagram Fishery Ghat, which was established 200 years ago. It was founded by the Portuguese. They created this market when business was needed in Chattagram, and they got the right to collect port duty. The traditional Chattagram Fishery Ghat has two locations. The location of the Fishery Ghat on Iqbal Road in Patharghata has been changed to a newer and larger scale Fishery Ghat at Lusai Kanya at the mouth of Rajakhali on the banks of the Karnafuli River. Depending on the season, different types of fish are traded every night from 3 pm to 8 am. In this market, the fish comes from every district, which is later transported to other corners of the country. And that is why the Chattagram Fishery Ghat is full of fish merchants. The fish worth millions are traded.
