Buying Tips for Fish
Buy whole fish if you can. It is easier to judge the quality.
The old rule of "checking for clarity of the eyes" doesn't always wash. Some
fish simply have cloudy eyes. Instead look for eyes that protrude, as if the
fish is animated.
Look under the gills. They should be bright, cherry, red
Whole fish should have a sheen. If the skin is leathery or has wrinkles, the
fish has lost enough moisture to be past it's prime.
