The Argentine seabass (Acanthistius brasilianus) is a species of

seabass in the family Serranidae.[1] It occurs on the South American continental shelf of the western Atlantic Ocean, where it used to be caught commercially for human consumption.[2][3]

Taxonomy and naming

The Argentine seabass was first described by

synonym of Acanthistius brasilianus.[4] [6] As a result of his participation in first voyage of HMS Beagle, Leonard Jenyns described a fish in 1840 that he named Plectropoma patachonica, and while many of the fishes he observed may have also been Argentine seabass, it is not totally clear whether P. patachonica is a true synonym of A. brasilianus.[4][7]

Etymology

The Argentine seabass'

thorn and Greek, istio (ιστίο) meaning sail, which is in reference to the spines along the front of its dorsal fin.[2][8] The species name, brasilianus, means "Brazilian". This is a reference to where the first specimens to be reported were caught.[4][5]

Description

The Argentine seabass has a deep, compressed body and is covered in

caudal fin. The Argentine seabass' dorsal fin has 13 spines and 15 soft rays, while its anal fin has only 3 spines and 8 rays.[2] They generally reach maturity when around 29 centimetres (11 in) in length though they have been recorded to lengths of 60 centimetres (24 in).[9]

Distribution and habitat

The Argentine seabass is a rare species,[1] found only in the southwestern Atlantic Ocean, along the coasts of Argentina, Uruguay, and Brazil.[2] They generally inhabit cold waters along the South American continental shelf.[2] Typically marine (they may also be found in brackish waters), Argentine seabass have been reported at depths from 15 metres (49 ft) to 60 metres (200 ft).[1]

Argentine seabass are known to prey upon crabs and small fish.

Imperial shag.[2]

Relationship with humans

Argentine seabass are consumed by humans, typically being caught off Argentina and, to a lesser extent, Uruguay.

Data Deficient by the IUCN.[1]
