Haliotis discus hannai Ino, 1953

Description

Geiger and Owen (2012).

Distribution

Native to coastal waters of East Asia ( Geiger and Owen 2012). In Chile this species is commercially harvested, with aquaculture farms in Caldera (27° S), northern Chile ( Valdovinos 1999). It was first introduced to the country in 1982 ( Flores-Aguilar et al. 2007).

Possible mechanism of introduction/Status

Imported to Chile for aquaculture ( Castilla et al. 2005; Flores-Aguilar et al. 2007).

Remarks

Herbivorous species, this species has an indirect impact on the communities of the native rocky kelp Lessonia nigrescens and Lessonia trabeculata , which are used as abalone food in Chilean aquaculture facilities ( Castilla et al. 2005; Flores-Aguilar et al. 2007). This species is also a primary introduction vector for the non-indigenous boring polychaete species Polydora uncinata Sato-Okoshi, 1998 ( Radashevsky and Olivares 2005). UA, II.
