SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Metacarcinus edwardsii

SPECIES NAME(s)

Mola rock crab, Jaiba marmola

Mola rock crab distributes from Arica region to Magellan Strait in Chile (Retamal et al. 2009) (Martinez 1986; in (Pardo et al. 2017)) and to the Beagle Channel (Vinuesa et al. 1999), from intertidal to 42 (Henriquez y Bahamonde, 1976 in (Pardo et al. 2017) or to 130 m deep (Campos, 1992 in (Pardo et al. 2017)). Genetic variation in individuals over 300 km apart have shown no significant variances, even when there are oceanographic conditions that difficult the process of larval transport, these conditions were not an obstacle for M. edwardsii (Rojas-Hernandez et al. 2014). The population structure is unknown.

Traditionally, this species has been englobed in a pool species called “jaibas” (crabs) for Chilean administration and fishermen, and it was not until the 90s that it was considered as a single resource in administration records (Yañez et al. 2015), accounting for a source of uncertainty in previous years.

Management (Subpesca) stands for the entire country, but assessments have focused on the most productive areas: VIII, X and XI regions (Yañez 2017). Being the X region the one providing most landings for the country (Pool et al. 1998)(Yañez 2017), management has singled it with a couple of administration measures: closure of fishermen registration for the resource (Subpesca 2016), and a different minimum extraction size (information from R. Ex. Nº 3606-2012 only available through (Cavieres et al. 2016) and (Yañez 2017).
