Spotfin croakers are fish belonging to the Roncador Stearnsii species and Sciaenidae family and are most commonly found south of Los Angeles Harbor, Southern California, and Baja California. They are the cousins of the yellowfin croaker and the white croaker.

The spotfin croaker (Roncador stearnsii) is the only species in the genus Roncador. They live along the beaches and bays in shallow sandy areas. They often feed on clams, worms, ghost shrimp, crabs and can crush a crustacean using their large throat teeth.

In appearance, they can grow more than 14 in (36 cm) and weigh around 6 lb (2.72 kg). Their name comes from a large black spot at the base of the pectoral fin. They usually have 11 or fewer dorsal fin spines which separate them from white croakers with 12 to 15.

They are known for moving around a lot with no definite pattern. The mating season is between June to September and takes place offshore. They are also called Golden Croakers as the male species turn into bright gold color during the time of mating. They are caught while fishing.

The best fishing season for spotfin croaker is in late summertime. It is very much valued as meat and has an excellent mild flavor, soft texture with very low fat and is loved by many people.
