How can you figure out if the fish is fresh?

• The fish's eyes should be clear and bulge a little. Only a few fish, such as walleye, have naturally cloudy eyes.
• Whole fish and fillets should have firm and shiny flesh. Dull flesh may mean the fish is old.
• Fresh whole fish also should have bright red gills free from slime.
• If the flesh doesn't spring back when pressed, the fish isn't fresh.
• There should be no darkening around the edges of the fish or brown or yellowish discoloration. The fish should smell fresh and mild, not fishy or ammonia-like.
