Caranx melampygus (bluefin trevally), is a large member of the jackfish family that is commonly targeted in Hawaii by both commercial and recreational fishermen alike.
Studies conducted over time in Hawaii have demonstrated that bluefin jacks often assemble at night to form large congregated groups before returning home each morning.
Early Life and Education
Bluefin jack are highly migratory fish that make long ocean journeys to reproduce. Being endothermic means their bodies generate heat that keeps their internal temperature higher than surrounding waters; this allows them to remain alive during long journeys across ocean waters.
This fish is an adept predator capable of hunting both small and large prey. Reports indicate it hunts bluefish and bunker in Hawaiian Islands waters before feeding on coral reef fish, making it one of the primary predators of coral reef systems.
Bluefin jacks typically school as juveniles but transition into becoming solitary with well-defined home ranges as adults. At times they will form temporary aggregations for breeding or hunting purposes.
