Ampliación del rango de distribución de Acanthistius pictus (Tschudi, 1846) (Serranidae: Osteichthyes) en aguas chilenas

Abstract

Acanthistius (Anthiinae) is distributed in the Indo West Pacifi c, Southeast Pacifi c and South Atlantic Ocean. The genus is constituted by 13 species, of which only Acanthistius pictus (Tschudi 1846) is recorded in Chile. A. pictus is an endemic serranid of the Eastern Pacifi c coast distributed from southern Perú (16°S) to north of Chile (26°S) (Pequeño et al. 2011). A. pictus is a rocky reef fi sh of shallow waters (5-30 m), that lives associated to caves and Lessonia trabeculata kelp forests (Cisternas & Sielfeld 2008). It is a carnivorous species that feeds mainly on crustaceans (Medina et al. 2004). It is also an economically important species which supports small-scale artisanal fi shing activities in the north of Chile (Godoy 2013).
