Family: Scombridae (Mackerels and Tunas)
The king mackerel has a body that is elongated and very compressed laterally. Its body color is mostly iridescent blue with greenish reflections near the dorsal and silver sides. The first dorsal fin has spines and is uniformly colored with the body while the second dorsal fin is much darker and comprised of rays. Following the second dorsal are eight to nine finlets. The bottom of the king mackerel is silvery with eight to nine finlets following the anal fin. The lateral line is found just above the shoulder and quickly dips down underneath the second dorsal fin and continues a curvy trail to the tail. They typically range from 2.3kg to 16kg, with most males under ten pounds and most females above. Average lengths are from 50cm to 90cm. There are some reports that have weights in the hundred pound range and lengths over a meter and a half. Juvenile kings and or males less than 4.5kg tend to have brown and yellowish spots (similar to Spanish mackerel). The tail has a large fork and the pectoral fins are scaled (Froese and Pauly, 2011; Kells and Carpenter, 2011). (Figure 1;, 2013)
