Caranx sansun; Print; The blacktip trevally (Caranx heberi); also known as the blacktip kingfish or yellowtail kingfish; is a species of large marine fish classified in the jack family Carangidae. The blacktip trevally is distributed throughout the tropical to subtropical Indian and West Pacific Oceans; ranging from South Africa in the west to Fiji; Japan and northern Australia in the east. It inhabits coastal waters throughout its range; preferring moderately deep clear waters over rocky and coral reefs. The blacktip trevally is easily distinguished by its yellow fins and a dark upper caudal fin lobe which gives the species its common name; as well as a host of other anatomical features. The species is known to reach a maximum size of 1 m. It is a benthopelagic predator; commonly forming small shoals where it takes a variety of fishes; cephalopods and crustaceans as prey. Little is known of reproduction in the species; and spawning is assumed to take place in more tropical regions of its range; with juveniles known to inhabit bays and large estuaries. Blacktip trevally are often caught using hook and line and various nets in commercial fisheries although don't make up a large part of the market. They are also popular with anglers due to their fighting ability and decent table qualities.; 1700-1880
