SHARK
Despite the shark’s fearsome reputation, it is good eating. Because their structure is supported only by cartilage, shark have no bones—a distinct advantage when it comes to cooking and dining. There are several hundred species of shark, but only a handful of these are harvested for food.  VarietiesPerhaps because of its reputation as the killer of the sea, shark is usually sold under a less recognizable variety name. Common thresher is a huge shark, growing to over 1,000 pounds (about 450 kg) in tropical waters, and has pinkish flesh. Soupfin, a smaller shark, provides the fin used as a gelatin base in Chinese soup. Blacktip, which are found in South Atlantic waters, are often sold in the form of pinkish-white steaks that have ruby-red edges. Mako, an Atlantic shark, is also called bonito shark, because it feeds on bonito tuna and has moist, pink, fine-grained meat. Bonito, a Pacific shark much like mako, has meat that looks and tastes like swordfish. Sandbar, another Atlantic Ocean shark, looks and tastes like blacktip. Spiny and smooth dogfish, also in this family, have richer more fatty flesh than other shark species. Most shark is sold as steaks or fillets. AvailabilityThe common thresher and bonito shark are plentiful April through August. Peak season for blacktip is November to April. Bonito, Mako, and Sandbar shark are available year-round. Preparation, uses, and tipsSharks must be bled immediately after they are caught, or the meat takes on an ammonia taste. Most shark is properly treated. A slight ammonia smell can be eliminated by soaking the meat in buttermilk or lemon juice for 30 minutes. Cut out any dark meat before cooking shark. Leave any skin attached, as it helps retain moisture during cooking. The secret to successful shark cookery is do not overcook. Whichever of the following cooking methods you choose, your shark will be cooked when its flesh becomes opaque, yet is still moist on the inside. Baking Place shark in a greased baking dish, or wrap in oiled foil and place on a baking sheet. Brush with melted butter or oil and season with salt and pepper, or cover with a piquant sauce. Bake in a preheated 450°F (230°C) oven until done, about 10 minutes per inch (2.5cm) of thickness. Grilling Place fillets or steak chunks on skewers directly on a greased grill, 4 to 6 inches (about 10 to 15cm) above prepared coals or fire. Baste with butter, oil, or marinade. Cook until opaque and moist on the inside, 6 to 8 minutes. Broiling Place fillets skin-side-down on a well-greased baking pan. Pour in enough stock to cover the bottom of the pan. Brush top of fish with butter or oil. Broil under preheated broiler 4 to 5 inches (10 to 12cm) from heat. Do not turn, but baste several times. Cook until opaque and moist on the inside, 6 to 10 minutes. Pan frying Fry shark in a small amount of hot butter or oil, turning once halfway through cooking time. Cook until opaque and moist on the inside, 4 to 8 minutes. Stir-frying Cut shark steaks or fillets into bite-sized pieces. Coat with cornstarch and stir-fry gently and briefly in hot oil before adding to your favorite stir-fried vegetables. Poaching Bring poaching liquid, consisting of water, broth, and herbs and spices, to a simmer. Slip shark in, then cover pan and keep liquid at a simmer for about 8 minutes per inch (about 2.5cm) of thickness. Steaming Place shark on a greased perforated rack over 1 to 2 inches (2.5 to 5cm) of rapidly boiling water. Cover with a tight-fitting lid and keep water at a constant boil through cooking time, 8 to 10 minutes per inch (2.5cm) of thickness of the fish. Nutritional HighlightsShark, 3.5 oz. (99g) (raw) *Foods that are an “excellent source” of a particular nutrient provide 20% or more of the Recommended Daily Value, based upon United States Department of Agriculture (USDA) guidelines. Foods that are a “good source” of a particular nutrient provide between 10 and 20% of the USDA Recommended Daily Value. Nutritional information and daily nutritional guidelines may vary in different countries. Please consult the appropriate organization in your country for specific nutritional values and the recommended daily guidelines. When cooked (fried, batter-dipped), shark (mixed species) provides 0.879 grams of omega-3 fatty acids, derived from EPA (0.258g), DHA (0.431g), and ALA (0.19g), per 100 grams of shark (mixed species). Health benefits and concernsMercury toxicity Nearly all fish contain trace amounts of methyl mercury, some more than others. In areas where there is industrial mercury pollution, mercury levels in the fish can be quite elevated. In general, however, methyl mercury levels for most fish are very low. However, shark and some other large predatory fish can contain methyl mercury levels in excess of the Food and Drug Administration’s (FDA’s) 1 part per million (ppm) limit. The FDA has advised pregnant women, women who could become pregnant, and nursing mothers to avoid fish that contain high amounts of methyl mercury, specifically shark, swordfish, king mackerel, and tilefish. Regular consumption of methyl mercury contained in these fish can harm the child's developing nervous system and may pose risks to the mothers as well. The FDA advises that other fish are permissible for pregnant and nursing women as part of a healthful diet. The agency suggests an acceptable level of 12 ounces per week of cooked fish (a typical serving size of fish is from 3 to 6 ounces). Permissible fish include shellfish, canned fish, smaller ocean fish or farm-raised fish. It is important to eat a variety of different species, rather than just one type of fish, in order to reduce the reduce risk of methyl mercury consumption.
