The barcheek trevally, Carangoides plagiotaenia (also known as the barcheek kingfish, shortridge trevally and oblique-banded trevally), is a species of moderately large marine fish of the jack family Carangidae. The barcheek trevally is distributed throughout the tropical waters of the Indo-west Pacific region, ranging from South Africa in the west to Japan, Australia and a number of small central Pacific islands in the east. The species inhabits inshore and offshore waters, found along the slopes of lagoons and out to deeper reefs on the continental shelf, where it preys on small fish and benthic crustaceans. It is a moderately large fish, growing to a maximum recorded length of 50 cm, and can be distinguished from similar species by its somewhat protruding lower jaw and the dark banding on its operculum. It is of minor importance to fisheries throughout its range, taken by trawling, hook and line methods and various inshore fish netting methods.
