Lean, Flaky-textured Fish Category
Lean fish generally don't pack as many vitamins and heart-healthy omega-3 fatty acids as, say, salmon or tuna, but they also have a milder flavor that's less "fishy."
A good way to judge whether a fish is lean is by its color. The lighter the fish, the leaner it is, which is why lean fish are sometimes call "white fish."
Many cooks sauté (aka pan-fry) lean, flaky-textured fish in butter or oil. It's done when the thickest part of the fillet flakes when you test it. You can also bake, broil, or--as the Brits do--coat cod with batter and deep-fat fry it.

Learn moreparrotfish
This tropical fish is delicious, but environmentalists worry that overfishing will harm coral reefs, since parrotfish clean them of algae. In addition, parrotfish also convert dead coral into white sand (up to 220 pounds of sand per fish per year) that we all love to walk and play volleyball on. As with all reef fish, parrotfish also contain a toxin called ciguatera, which can cause food poisoning. You can reduce the risk by not eating the fish's head or organs.

Learn moretaape
This beautiful fish was introduced to Hawaii in 1958, and it multiplied so quickly that it's now crowding out some native species. Buying this fish helps prod fishermen to rid Hawaiian waters of this nuisance. It's a tasty fish, too, though there's concern that some of these fish may carry ciguatera, a toxin that affects certain reef fish.
