The bar jack, also known as the carbonero, cojinúa, red jack, blue-striped cavalla or passing jack, is a common species of inshore marine fish classified in the jack family, Carangidae. The bar jack is distributed through the western Atlantic Ocean from New Jersey and Bermuda in the north to Venezuela and possibly Brazil in the south, with the largest population in the Gulf of Mexico and West Indies. The bar jack is most easily distinguished from similar jacks by the dark horizontal bar which runs along the back and down the caudal fin. It is often accompanied by an electric blue stripe immediately below. Other more detailed differences include dentition and soft ray counts. The bar jack is a moderately large species, growing to a recorded maximum of 65 cm (26 in) and a weight of 6.8 kg (15 lb).
