Seafood lovers thronged the Kasimedu harbour and Chintadripet fish market on Sunday violating golden rules of the pandemic. There was no social distancing and very few people wore masks. A senior fisheries official said more than 60 tonnes of fish had arrived at the Kasimedu harbour in fibre boats and bigger vessels. While wholesale traders visited the market from midnight, members of the public began to turn up in droves after dawn. By 7am, police personnel and officials of the fisheries department were unable to control the crowd. Many customers have come without a mask. It is so scary, said Jayaram, a fisherman. The situation was no better at the Chintadripet market where the corporation had allowed 20 shops to sell fish but on weekends retailers open 40 more stalls. On Sunday morning, more than 2,000 people rushed to the market to buy fish. Many were not wearing masks. Officials from the fisheries department and Greater Chennai Corporation expressed concern over the swelling crowd. An official said that despite several warnings, people are not following social distancing norms. More police personnel are needed in such places to control the crowd. Otherwise, the fish markets will become another Koyambedu from where coronavirus will spread to many parts of the city, an official said.
