Eleginops maclovinus, the Patagonian blenny, Falkland's mullet or rock cod, is a species of notothenioid fish[1] found in coastal and estuarine habitats around southernmost South America, ranging as far north as Valparaíso on the Pacific side, and Uruguay on the Atlantic side.[2] It is also found around the Falkland Islands, where it has been featured on a stamp.[3] It is the only member of its genus, which is the only member of the family Eleginopsidae.[4] Its English names refer to the vaguely blenny-, mullet-, or cod-like appearance, but it is not related to true blennies, mullets, or cods. Locally, it is often called róbalo,[5] a name also used for the common snook.

It is commonly fished in parts of its range.[6] It is an omnivore, tending towards carnivore. In some parts of its range, it is especially fond of Paracorophium,[5] but it is opportunistic, and its exact diet depends on the availability in the habitat where the individual fish lives.[2]

It reaches about 105 cm (3.44 ft) in length, and can live for 10 years.[2] It is a protandric hermaphrodite, and males predominate in lengths below 52 cm (1.71 ft), while female predominate above.[7] It has a diploid number of 48, and a fundamental number of 54.[4]
