The abundant and nutritious patagonian blennies were apparently not consumed by the indigenous people of Tierra del Fuego. Religious significance to the indigenous people In Argentina and Chile, it is often called róbalo, a name also used for the common snook. The Patagonian blennie has been featured on a stamp in the Falkland Islands issued in 1994. There have been trials for the use of this species as a cleaner fish to control sea lice in the aquaculture of salmonids in Chile. The Patagonian blennie is commonly fished in parts of its range. It appears to be a protandrous hermaphrodite, in one study males were found at lengths between 19 and 45 cm (7.5 and 17.7 in) while females were found at 27 and 58 cm (11 and 23 in) which suggested that the sex change from male to female took place at ages between 2 and 7 years old. In some parts of its range, it is especially fond of Paracorophium, but it is opportunistic, and its exact diet depends on the availability in the habitat where the individual fish lives. The Patagonian blennie is an omnivore, tending towards carnivore. They are found in coastal, estuarine, and tidally influenced rivers. The Patagonian blennie is found in the southeastern Pacific and southwestern Atlantic Ocean from Valparaiso in Chile south to Tierra del Fuego and north along the coast of Patagonia in Argentina, It is also found around the Falkland Islands. It reaches about 105 cm (3.44 ft) in length. Both dorsal fins are greyish in colour and the caudal fin is brownish and these fins have yellowish margins. The colour of the body is blue brown above and silvery yellow below. The Patagonian blennie has 7-8 spines in its first dorsal fin and 23-27 soft rays in its second dorsal fin. The Eleginopidae are the sister family of the Bovichtidae and Pseudaphritidae and these are all sister to the rest of the families in the Notothenioidei which have been placed in the suggested superfamily Cryonotothenioidea. The specific name maclovinus means belonging to the Maclove Islands, an old name for the Falkland Islands. Gill then placed it in the monotypic family Eleginopidae in 1893. Cuvier's genus name was later shown to be unavailable as it was a junior synonym of the cod genus Eleginus described by Gotthelf Fischer von Waldheim in 1813, Theodore Nicholas Gill renamed the genus as Eleginops, meaning "similar to Eleginus in 1862. The Patagonian blennie was first formally described in 1830 as Eleginus maclovinus by the French zoologist Georges Cuvier with the type locality given as the Falkland Islands. It is found in coastal and estuarine habitats around southernmost South America. The Patagonian blennie ( Eleginops maclovinus), also known as the rock cod, is a species of marine ray-finned fish, belonging to the monotypic family Eleginopidae and monotypic genus Eleginops.
