Blackfin scad

The blackfin scad (Alepes melanoptera) (also known as the shortfinned trevally and Chinese trevally) is a species of tropical marine fish of the jack family Carangidae. The species inhabits inshore waters throughout the Indo-Pacific region, although is rare in the western Indian Ocean. It is not a large species, with the largest reported capture being 25 cm, and it is distinguished readily from similar species by the prominent black dorsal fin. It is a predator which feeds on planktonic crustaceans, but little else is known of its biology. The blackfin scad is a minor food fish throughout its range, and is highly valued in Cambodia and Thailand.
