The White Croaker (Genyonemus lineatus), is a species of croaker occurring in the Eastern Pacific. White croakers have been found from Magdalena Bay, Baja California, to Vancouver Island, British Columbia, but are not abundant north of San Francisco. The white croaker is the only species of in the genus Genyonemus. Other common names for the fish include Pasadena trout, Tommy croaker, and little bass.
The body of the white croaker is elongate and somewhat compressed. The head is oblong and bluntly rounded, with a mouth that is somewhat underneath the head. The color is incandescent brownish to yellowish on the back becoming silvery below. The fins are yellow to white. The white croaker is one of five California croakers that have mouths located under their heads (sub-terminal).
White croakers eat a variety of fishes, squid, shrimp, octopus, worms, small crabs, clams and other items, either living or dead. While the ages of white croakers have not been determined conclusively, it is thought that some live as long as 15 or more years. Some spawn for the first time when they are between 2 and 3 years old. At this age they are only 5 to 6 inches long and weigh less than 0.10 pounds. The largest recorded specimen was 16.3 inches, no weight recorded.
White croakers swim in loose schools at or near the bottom of sandy areas. Sometimes they aggregate in the surf zone or in shallow bays and lagoons. Most of the time they are found in offshore areas at depths of 10 to 100 feet. On rare occasions they are fairly abundant at depths as great as 600 feet.
