SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Merluccius gayi gayi

SPECIES NAME(s)

South Pacific hake, merluza común

Several research studies have been conducted on the stock structure of South Pacific hake. (Payá et al. 1997) using morphological characteristics, genetics, parasitology and latitudinal comparisons about the average length of sexual maturity identified a unique stock in Chile; and (Galleguillos et al. 2000), supported this conclusion analysing polymorphic loci of distinct localities along Chile. (George-Nascimento 1996) and (Oliva and Ballón 2002) in turn consider the existence of two stocks according to morphology and parasitology of the species in Puerto Montt and Coquimbo. Finally and more recently (Vidal et al. 2012) using mitochondrial DNA presented a division in three genetic stocks: in Perú, Valparaíso-Coquimbo and Corral. 

The Fisheries Development Institute (Instituto de Fomento Pesquero, IFOP), using the results obtained by (Tascheri et al. 2013) applying length composition and relative abundance data, corroborate the scenario that considers that mixing of the individuals is enough to assume a unique stock to assess along fishery management units for the following regions: Comquimbo, Valparaíso, O'Higgins, Maule, Ñuble, Biobío, Araucanía and Los Ríos (IFOP, 2013).


ANALYSIS

Strengths
  • The recent General Law on Fisheries and Aquaculture established clear rules for setting Management Commissions and Management Plans, stated that the minimum goal for every fishery is to achieve maximum sustainable yield (MSY), and makes mandatory an observer program to address discarding, which is not allowed.
