About the species

Almaco jack are a pelagic, often deepwater species found in tropical and temperate waters around the world. In the Atlantic and Gulf of America (formerly Gulf of Mexico), they are targeted by both the recreational and commercial fishing sectors due to their size and food quality.

In the Pacific Islands where there is a sizable market, almaco jack is farmed in deep water near the Island of Hawaiʻi. The fish are spawned and raised in on-land hatcheries until they are large enough for transfer to submersible marine net pens. Almaco jack also is a candidate for commercial aquaculture in the Gulf of America and U.S. Caribbean.
