Patagonian grenadier, Hoki
merluza de cola (Spanish)
Patagonian grenadier is distributed in the Southeast Pacific and Southwest Atlantic, from southern Chile to Argentina. This species, also known as Chilean hoki, has been assessed as a single stock unit, supported by genetic studies (Stewart & Hanselman, 2012), however, recent studies suggested high mixture between Pacific and Atlantic populations (Schuchert et al., 2010; Niklitschek et al., 2013).There have been joint workshops between Chilean and Argentine research institutes but there are two separate assessment units: Patagonian grenadier - Argentine and a Patagonian grenadier - Chilean (GIUSSI et al. 2016).
Two management areas are defined for the hoki fishery in Chilean waters: the central-south unit comprised by the V-X regions and the southern-austral unit including the XI and XII regions.
