- 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.
Horse-eye jack (Caranx)
The horse-eye jack has a deep and compressed body similar to a jack crevalle, but the horse-eye jacks head is more rounded. Known for its large eyes, the horse-eye is gray to bluish-black above and a silvery-white on its sides and below. A row of dark-colored scutes extends from the middle of the body to the center of the forked tail fin. In addition to the dark and light contrast on the overall body, the horse-eye jacks tail fin is yellow, which is often highlighted in black on the top edges. The horse-eye can also be identified from other jacks by its chest, which is covered entirely in scales.
The horse-eye jack’s diet consists of fish, crabs and shrimp. Although individual fish will seek out crabs and other organisms on or near the bottom, most feeding takes place as schools of horse-eye encounter schools of small baitfish and shrimp.
The horse-eye jack can be found in the western Atlantic Ocean from New Jersey to Bermuda and from the northern Gulf of Mexico to Brazil. In the eastern Atlantic they can be found off the coast of northwest.
Horse-eye jacks are mostly found in open water at a variety of offshore depths, but have been known to travel up coastal streams and rivers. Adults are found among reefs in open water, whereas younger horse-eye typically select sandy shores or muddy bottoms to inhabit. They often school in both small and large groups in water up to 60 feet deep, but individually they may inhabit depths of up to 400 feet or more. They generally seek water with an average annual temperature of 63 F.
- Although edible, the horse-eye is not known for its taste. However, its quality of meat may improve by cutting off its tail and bleeding the fish immediately after catching.
- Along with other jack, horse-eye jack have been associated with ciguatera poisoning, which is caused by consuming a fish whose flesh is infected with a potent neurotoxin called ciguatoxin.
- Considered a friendly fish to humans, horse-eye jacks will often approach scuba divers.
