Description

The rough scad is a streamlined, silvery jack of the family Carangidae reaching about 40 cm. The torpedo-shaped body has large eyes, two dorsal fins and a row of bony scutes along the curved lateral line that give firmness for fast swimming. The species forms large schools in open coastal water over the continental shelf along the American Atlantic coast. As a fast hunter it eats zooplankton, small fish and crustaceans. Through its enormous numbers it is an important prey fish for larger predators and seabirds and a link in the coastal food web; it is netted for bait and food.
