Fish – How to tell if fish is fresh

fishshopping

I love fish, and I love cooking it. The thing is, I don't have any idea how to buy fish.

Considering common fish in a grocery store (salmon, whitefish, tuna, grouper, etc.), how can I tell a good specimen from a bad one? When the difference is not clear, which way should I err?

Is there any different set of criteria, when I'm buying fish at an outdoor market?

As a rule of thumb for a whole fish, and not a fillet -

  • the gills should be bright red
  • the skin/scales should be bright and shiny like metal
  • this fish shouldn't really smell of anything except 'watery'
  • the flesh should rebound quickly when pressed
  • the eyes should be bright and clear
  • really fresh fish is also quite slimey to touch if it's straight out of the water. I remember being quite surprised at this from my first fishing trip a few years back.
