The body of the white seabass is elongate, and somewhat compressed. The head is pointed and slightly compressed. The mouth is large, with a row of small teeth in the roof; the lower jaw slightly projects. The color is bluish to gray above, with dark speckling, becoming silver below. The young have several dark vertical bars. The white seabass is closely related to the California corbina, but is the only California member of the croaker family to exceed 20 pounds in weight. The largest recorded specimen was over 5 feet, 93.1 pounds. They are most easily separated from other croakers by the presence of a ridge running the length of the belly.
The diet of white seabass includes fishes, especially anchovies and sardines, and squid. At times, large fish are found which have eaten only Pacific mackerel. At the minimum legal length of 28 inches, the average white seabass is about 5 years of age, weighs about 7.5 pounds and has been sexually mature for at least one spawning season.
In California, there is a 28 inch size limit and current fishing regulations should be checked concerning bag limits.
