Kingklip (Genypterus capensis) is an eel-like marine fish of the cusk-eel family (Ophidiidae), caught mainly by trawl and longline in the cold Atlantic waters off southern Africa, where it lives on the continental shelf and slope. Its firm, white, boneless flesh is valued for fillets and for further processing into portions, and the catch is normally marketed frozen — glazed and block-frozen at sea or ashore — with smaller volumes sold fresh. Processors handle it like other lean whitefish: grading, trimming, portioning and freezing promptly to protect texture and flavour, since slow freezing damages the delicate flesh. As a lean, high-protein fish it suits health-positioned ranges, and certified sustainable sourcing is increasingly specified by buyers.
