On the 2nd floor of Carrefour in the store of the same name, is a fish counter with an array of fish that can be steamed, fried, or spiced. I am quite a regular visitor as I just love fresh white fish. I am no connoisseur so I'm curious if anyone knows if the fish are indeed fresh?

Just check the eyes, they should be reasonably clear, usually when they are going off they get a pink or orange milky tinge in the eyes, but if you have a Thai missus she should tell you that super market fish are never fresh, tesco carrefour and the likes, better to go down the sea front markets. With the live fish pick the ones with the darkest colours, the lighter ones have probably been in the plastic tub for some days. Shell fish ie mussels and clams should be open, yet close when you touch them, and when cooked they should open. Squid should be clear and not murky white. Hope this helps you mate, I love sea food mak mak:-)

yes, the Naklua market is the best place for fresh fish, and cheap too

My missus checks the fish by looking at the eyes (if they wink at you they're fresh ) and checks the gills.

Some are fresh and some aren't so you have to check
