amberjack

Amberjack is a common name for several large marine fishes in the genus Seriola of the family Carangidae. The term most often refers to the greater amberjack (Seriola dumerili) and the yellowtail amberjack (Seriola lalandi); in some regions it also includes the black amberjack (Seriola rivoliana). Regional usage varies.

Amberjack are large, fast-swimming predatory fish with an elongated, strongly compressed body. They typically display a blue-green dorsal surface and silvery sides, with yellow or amber on the tail and fins. They commonly reach lengths of roughly one to two meters; exceptional individuals may be larger.

They inhabit temperate to tropical oceans worldwide, often offshore around reefs, wrecks, and floating structures, and they show seasonally migratory patterns in some populations.

They are opportunistic carnivores, feeding on smaller fish, squid, and crustaceans. They are diurnal and can be solitary or form small to moderate-sized groups, especially when young.

Reproduction occurs in warm, open-water areas with pelagic eggs. Spawning timing varies by region. Amberjack are valued as sport fish for their strength and as commercial species in many fisheries, and several Seriola species are cultivated in aquaculture.
