What is Round Scad?
Round scad, scientifically known as Decapterus spp., belongs to the mackerel family and is a pelagic fish species commonly found in warm and temperate oceans across the world. Their various regional names, such as mackerel scad or chub mackerel, reflect their widespread distribution. Round scad typically grow to lengths between 6 to 12 inches (15-30 cm) and weigh around 1 to 4 ounces (30-120 grams). These fish have elongated bodies characterized by a striking blue-green dorsal side and shimmering silver or white undersides. One of their key identifying features is the presence of a prominent lateral line that runs along their sides, aiding in navigation and sensory perception.
