Pacific crevalle jackW
Pacific crevalle jack

The Pacific crevalle jack is a species of large marine fish classified in the jack family Carangidae. The species is distributed through the tropical waters of the eastern Pacific Ocean from California in the north to Peru in the south, including several offshore islands. The species is best identified by its deep body and mostly unscaled breast, as well as other more detailed anatomical features. The species is known to grow to a maximum length of 101 cm and a weight of 19.7 kg. Disagreement on the status of the species has been significant in the scientific literature, with many claiming it to be conspecific with or subspecific to the Atlantic Caranx hippos. The most recent review of the crevalle jacks strongly concluded it to be a separate species based on the development of hyperostosis and fin colouring. It is predominantly a schooling inshore species, inhabiting sandy and rocky substrates, although larger individuals are occasionally found living pelagically to depths of 350 m. The Pacific crevalle jack is a fast-swimming predator, taking a variety of fish, crustaceans, and other small invertebrates. Spawning is thought to occur year-round, although peaks occur during November and May. The Pacific crevalle jack is an important species to commercial fisheries, with data available from Colima in Mexico indicating it accounts for up to 15% of the entire yearly catch. Pacific crevalle jack are highly rated gamefish, taken by both bait and a variety of lures, but are considered relatively poor quality food.

It occurs in large schools, sometimes with gizzard shad, and can be seen on the surface at dawn and dusk. The threadfin shad may reach lengths of 8 in (200 mm), but only rarely. This fish is very sensitive to changes in temperature and dissolved oxygen, and die-offs are frequent in late summer and fall, especially when water temperature drops to 42°F. The threadfin shad is a favorite food for many game fishes, including striped bass, largemouth bass, smallmouth bass, and catfish. This fish is widely introduced throughout the United States as a forage for game fish.
