From Trash to Treasure: The Tale of the Crevalle Jack

Crevalle jack, Caranx hippos, are a voracious predatory fish that inhabit tropical and temperate waters on both sides of the Atlantic Ocean, from Nova Scotia to Uruguay and from Portugal to Angola. They are common in inshore, nearshore,and offshore waters and often school around structure and hard-bottomed areas. Crevalle jack are one of the largest species of jacks (the all-tackle world record weighs more than 60 pounds!) and are distinguished by their broad,muscular bodies, steeply profiled head, and black markings above their pectoral fins and on their operculum (gill plate). Known to consume a widely variable diet of fish and crustaceans (e.g., shrimp and crabs), their speed and agility make them formidable predators throughout their range.
