Biology and Fisheries
The level of biological information known about each species in Caranx is generally related to how important they are commercially. All species are predatory fish, taking smaller fish, crustaceans and cephalopods as prey. Most species form schools as juveniles, but generally become more solitary with age. Reproduction and growth has been studied in a number of species, with these characteristics varying greatly between species.
All species in Caranx are of at least minor importance to fisheries, but a number are much more so due to their abundance in certain regions. Most are considered to be gamefish, with some such as the giant trevally and bluefin trevally highly sought after by anglers. They are generally considered poor to fair quality table fishes, and have had a number of ciguatera poisoning cases attributed to them.
