- Albacore are the only tuna allowed by the Food and Drug Administration to be marketed and sold as white meat. Because of this distinction, albacore is the most prized tuna meat in the United States.
- Albacore is considered inferior to other tuna meat in Japan for the exact same reason. Only some members of the billfish family (marlins, swordfish) and the mako shark are faster. Albacore have been recorded going over 55 knots.
- Close to 200,000 tons of albacore are harvested every year, most coming from the Pacific Ocean.
Black grouper (Mycteroperca)
Black grouper have the typically stout body and large mouth of the grouper family. Like many bottom fish, black groupers can be a variety of colors including olive, gray or reddish brown to black. There are dark gray rectangular markings and brassy blotches on the side and back. The outer third of the second dorsal, anal and tail fin are black. The first dorsal fin has spines while the second has soft rays. The tail is unforked and shaped like a broom.
Black grouper are opportunistic feeders that will chase food but most often hunt by ambush. They are carnivores, feeding largely on fish such as small grunts and coronet fish and larger crustaceans. Along with their cousins, the red grouper, they prey heavily upon shrimp and squid. Young black groupers feed mainly on crustaceans.
Black grouper are found in the western Atlantic Ocean from New England to southern Brazil, though they are not common north of the Carolinas. They inhabit the southern Gulf of Mexico but not the northern portion.
Adult black grouper are an offshore and deep-sea species, often stationing themselves just above the bottom over reefs or wrecks in water 60 to 300 feet deep. They may be found in shallower water during the cooler seasons. They are a non-schooling solitary species, known to hide out in caves, crevices on reefs and shipwrecks. They are also a warm water species that prefers tropical waters. Young black grouper usually inhabit shallow waters closer to shore over reefs or in estuaries, particularly around jetties, piers, wrecks and bridges. Some of these young stay in these environs their entire life, but most migrate farther out to sea.
- Although black grouper are abundant they are a shy species and will swim away if approached by scuba divers.
- The world record for black grouper is 114 pounds.
