IDENTIFICATION

SCIENTIFIC NAME(s)

Cervimunida johni

SPECIES NAME(s)

Blue squat lobster, Langostino amarillo, Yellow squat lobster

COMMON NAMES

Chilean squat lobster

Population structure is not fully known, but two Blue squat lobster stock assessments are conducted in Chilean waters: a Chilean northern assessment area – including Region III and north of Region IV  (up to 30°30’S) and a Chilean southern assessment area – spanning  from southern Region IV  to the southern limit of Region VIII (30°30’ to 38°48’ S) (IFOP 2013).

RECOMMENDATIONS

CATCHERS & REGULATORS

1. Review the FishSource profile and publish or share online relevant missing information in your possession or those accessible to you.
2. Encourage scientists to share their studies/publications with FishSource by commenting on the profile and uploading a hyperlink to the document.
3. Work with scientists on the collection of data and make them accessible online.
4. Encourage the institutionalization of data collection and publication.

RETAILERS & SUPPLY CHAIN

1. Advise your suppliers that currently the FishSource profile reflects that there is not enough information publicly available on this fishery and you are unable to make an accurate determination of the sustainability status. Request that they advise the relevant authorities of the situation and that efforts need to be made to collect and publish data and disclose data sources to FishSource to better inform buying decisions.

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

FishSource Scores

MANAGEMENT QUALITY

As calculated for 2010 data.

The score is ≥ 6.

No specific management plan is known for this fishery, but several management measures such as TACs and closed season, are in place to protect the stock. Managers have been able to keep the stock at a stable and healthy condition (SUBPESCA, 2010).

As calculated for 2011 data.

The score is 9.9.

This measures the Set TAC as a percentage of the Advised TAC.

The Set TAC is 3.01 ('000 t). The Advised TAC is 2.99 ('000 t) .

The underlying Set TAC/Advised TAC for this index is 101%.

As calculated for 2010 data.

The score is 10.0.

This measures the Landings as a percentage of the Set TAC.

The Landings is 2.61 ('000 t). The Set TAC is 3.01 ('000 t) .

The underlying Landings/Set TAC for this index is 86.8%.

STOCK HEALTH:

As calculated for 2010 data.

The score is ≥ 8.

Spawning stock biomass is at the highest levels of the data series, and the stock reproductive potential is estimated at 73% of its unfished condition (SUBPESCA, 2010).

DATA NOTES

1) No biomass or fishing mortality reference points are known for this stock, thus scores 1, 4 and 5 couldn’t be computed. Qualitative scores have been attributed to scores 1 and 4.
2) TACs in the scores data sheet so not include the annually set share for scientific purposes.
3) The southern portion of the management unit III-IV overlaps with the distribution of the southern Chilean blue squat lobster (SUBPESCA, 2010). However, spawning stock biomass (SSB) in the data sheet only relates to the northern stock.
