Bluefin Trevally

The Bluefin Trevally, Caranx melampygus, is a strong predatory fish, with a diet dominated by fish and supplemented by cephalopods and crustaceans as an adult. Juveniles consume a higher amount of small crustaceans, but transfer to a more fish based diet as they grow. The species displays a wide array of hunting techniques ranging from aggressive midwater attacks, reef ambushes and foraging interactions with other larger species, snapping up any prey items missed by the larger animal. The bluefin trevally reproduces at different periods throughout its range, and reaches sexual maturity at 30–40 cm in length and around 2 years of age. carango pinna blu

The Carangidae are a family of fish which includes the jacks, pompanos, jack mackereles, runners, and scads. They are marine fishes found in the Atlantic, Indian and Pacific Oceans. Most species are fast swimming predatory fishes that hunt in the waters above reefs and in the open sea; some dig in the sea floor for invertebrates. The largest fish in the family, the greater amberjack, Seriola dumerili, grows up to 2 m in length; most fish in the family reach a maximum length of 25–100 cm. The family contains many important commercial and game fish, notably the Pacific jack mackerel, Trachurus symmetricus, and the other jack mackerels in the genus Trachurus.
