SWORDFISH
Swordfish, along with marlin, spearfish and sailfish are referred to as billfish. This refers to the sword-like projection of the upper jaw. Swordfish were first described by Aristotle who used the Greek word xiphias meaning "sword." The Romans used the term gladius which also meant "sword." The scientific name for swordfish, Xiphias gladius, is a combination of both names.
Swordfish are one of the fastest fish, being able to reach up to 60 mph. They are a solitary fish, and hunt using their sword to slash sideways through schools of smaller fish (e.g. manhaden, mackerel, squid) stunning or killing their prey, then eating at their leisure.
Shaped like an oversized mackerel, the body is thickest in the shoulder area, tapering to the tail which is reinforced by a keel on each side. They vary in color from deep brown to black on the back and upper surface of the body to almost white on the side and lower body. The long upper- jaw and snout form a flat, sharp double-edged sword which may be as much as one third the total length of the fish. They are large, aggressive fish sometimes reaching 14 feet in length and a weight of 1,200 pounds.
Swordfish are found throughout the world including Florida's Gulf and Atlantic waters. They feed on a variety of fish and squid, foraging over great depths and distance. They are formidable opponents when harpooned and have been known to pierce the sides and planks of ships with their swords. In recent years, longlines have been used to catch swordfish and have been effective.

PREPARATION
Keep raw and cooked seafood separate to prevent bacterial cross-contamination.
After handling raw seafood thoroughly wash knives, cutting surfaces, sponges and your hands with hot soapy water.
Always marinate seafood in the refrigerator.
Discard marinade; it contains raw juices which may harbor bacteria.
When marinade is needed for basting reserve a portion before adding raw seafood.
COOKING
The general rule is 10 minutes per inch of thickness, at the thickest part of the fillet or steak, at 400-450 degrees F.
If fish is cooked in parchment, foil or a sauce, add 5 minutes to the total cooking time.
Fillets less than 1/2 inch thick do not need to be turned during cooking.
Fish cooks quickly. Do not overcook.
Fish is done when the flesh becomes opaque and flakes easily when tested with a fork.
Poaching, steaming, baking, broiling, sautιing, microwaving are excellent low-fat cooking methods, if you do not add high fat ingredients.
Marinate in your favorite salad dressing prior to cooking.
Broil, bake, steam or microwave, then cube and add to pasta or salad greens for a delicious salad.
Broil or grill with lime-butter and seasoned salt.
Oil the grill to prevent fish from sticking.
Bake whole fish with a crab or shrimp stuffing.
Add leftover fish in broken pieces to salads, soups or sauces.
