Description

The Patagonian rockcod is a notothen of the family Nototheniidae from the southwestern Atlantic, around Patagonia and the Falkland Islands. The species reaches about 23 cm and has a stocky, brown mottled body that blends well against the rocky bottom. It lives demersally in shallow, cold coastal water. Like other notothenioids it has antifreeze glycoproteins in its blood that prevent freezing in the icy water. The diet consists of small crustaceans, worms and small fishes. The species is eaten locally as a food fish.
