Fish Category
Cooks often divide fish into two categories, fatty (or oily or rich) and lean. These two categories can be split again, by whether their texture is firm or flaky.
Fatty, firm fish include tuna, eels, catfish, shark, and swordfish.
Fatty, flaky fish include salmon, herring, mackerel, and sardines.
Lean, firm fish include grouper, lingcod, mahi-mahi, and striped bass.
Lean, flaky fish include cod, flatfish, and rockfish.
Shellfish aren't technically fish, but they're usually sold at the fish counter, so we've lumped them into this category.

Learn moreossetra caviar
In recent years, over-fishing in the Caspian Sea has greatly depleted sturgeon populations. Please consider using caviar and roe from more abundant species until the Caspian Sea sturgeon populations can recover. Ossetra caviar is brown and more strongly flavored than beluga caviar. Don't confuse ordinary ossetra with the rare and expensive golden ossetra = imperial caviar. If substituting an inferior caviar, consider perking it up with a splash of fresh lemon juice.

The French like to serve these raw in the shell, with just a squirt of fresh lemon juice, but they can also be fried, grilled, or gently poached.

Learn morepaddlefish roe
Paddlefish swim in Southern rivers and they're relatives of sturgeons--the fish that produce the world's most expensive and exquisite caviars. Paddlefish roe is very similar to sevruga caviar, only it's cheaper. Since Caspian Sea sturgeon are rapidly becoming depleted from over-fishing, many people are turning to paddlefish roe as a substitute for caviar.
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.
