Rough scad (Trachurus lathami)

The Rough scad (Trachurus lathami) is a marine fish of the family Carangidae. Native range: Western Atlantic, Canada to Maine, USA and northern Gulf of Mexico to northern Argentina; apparently rare in the West Indies.

Biology

Coastal pelagic and demersal over continental shelves. Rare in oceanic insular areas. Juveniles associate with the jellyfish Chrysaora lactea in Southwestern Atlantic. Preyed on by juvenile comb grouper (Mycteroperca acutirostris) when protection given by the jellyfish fails. Often in schools. Feeds on small invertebrates. Marketed fresh locally and considered a good food fish. In southern Brazil found in 147 m depth.
