Dongdi seafood wholesale market is a good place if you are in Xiashan, and Dongfeng market is also rich in species.
If you are in Chikan, you can go to Nanhua Market (there are many species here, but the price will be higher) and Beiqiao Market (there are a few species, but the price is negotiable)
If you go to Diaoshun or Leizhou, Xuwen and Suixi, congratulations again, cheaper, richer and fresher seafood is waiting for you.
