Jack Mackerel

Jack mackerel (Trachurus symmetricus) are a long-lived fish found in the upper 200 meters of water throughout the northeastern Pacific Ocean. They are active predators of copepods, squid, anchovy, and other fishes. In addition, they serve as prey for larger tuna, billfish, and marine mammals. Although infrequently caught, jack mackerel appear in both recreational and commercial landings. Historically, landings of jack mackerel increase when other coastal pelagic species are not readily available, and declines in landings can be attributed to fishermen targeting the more readily and easily accessible Pacific sardine and Pacific mackerel. Jack mackerel are monitored under the Coastal Pelagic Species Fishery Management Plan.
