Tips for choosing fresh fish

Eyes

Fresh fish will have clear, dark eyes that are slightly bulging. If the eyes are cloudy, pink, or sunken, the fish is likely old and spoiled.

Flesh

To test the freshness of the fish, gently press your finger on its flesh. If the fish is fresh, the flesh should quickly spring back. If your finger leaves an indent, the fish is not at its best.

Gills

The gills of fresh fish will be bright red or pink. If they appear dull or dark, the fish is not fresh.

Fresh fish gills are red or pink.

Skin and Scales

Look for fish with tight, shiny scales and clear skin free from any spots or marks.
