The slender kingklip, a member of the cusk eel family, comprises four species: red (G. chilensis), golden (G. blacodes), South African (G. capensis) and black (G. maculatus). Depending on the species, kingklip can reach 5 to 6 feet long and 50 pounds, but most found on the market average 10 pounds. Kingklip are found in waters as deep as 250 fathoms off South Africa, New Zealand and Australia as well as off the coasts of Argentina and Chile. They are caught mostly by trawlers, often as a bycatch, and by hook and line. In Europe, kingklip is marketed as cusk eel. In New Zealand it is called ling, and in South America, congrio (cusk eel). Golden, red and black kingklip are marketed internationally, but the U.S. market prefers golden and red.
