Talaat Mahachai, the local market in Samut Sakon, has one of the largest fresh seafood markets in Thailand, which due to the nearby Tachin sea port, has a lot of fresh seafood and fish on offer.

The market is located along the Mahachai Canal and Mae Khlong-Mahachai Railway that links Samut Songkhram with Bangkok, and runs from the middle of the railway station, including the space on the tracks, to the local harbour.

Its propitious location made the market one of the main seafood distribution centers that caters to the capital.
