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.

1.STOCK STATUS

STOCK ASSESSMENT

Last updated on 3 June 2014

No stock assessment is known to be formally or regularly conducted.
Two assessment models were performed to determine the status of the stock using commercial landings 1997-2000 from 6 federal states: model Thompson & Bell by Klippel et al. (2005b) and a yield-per-recruit analysis, considering natural mortality (M) at 0.2 (Klippel et al., 2005c).

SCIENTIFIC ADVICE

Last updated on 3 June 2014

Brazil lacks a formal scientific research institute for fisheries. Assessments are conducted by universities. No formal scientific advice is known to exist.
Klippel et al. (2005c) advised the reduction of fishing mortality and of 50% in the number of longline vessels. Catch limits are recommended at around 3,500 tons. Some problems were detected in official statistics of landings data: not available for all federal states and in time and way of presenting data (Klippel et al., 2005a).

REFERENCE POINTS

Last updated on 3 June 2014

Klippel et al. (2005c) estimated F0.1 at 0.16 and Fmax at 0.37.

CURRENT STATUS

Last updated on 3 June 2014

Time-series for biomass and fishing mortality are not available. The current status of the stock is not known. Landings at 5,320 tons in 2012 were above the catch limit of 3,500 tons advised by Klippel et al. (2005c).

TRENDS

2.MANAGEMENT QUALITY

MANAGERS' DECISIONS

Last updated on 3 June 2014

In 2009 (Law 11.958) the Ministry of Aquaculture and Fisheries (Ministério de Aquacultura e Pescas, MAP) was created assuming definition and establishment of fisheries’ management measures, functions previously under the Special Secretary of Aquaculture and Fisheries (Secretaria Especial de Aquicultura e Pesca, SEAP) jurisdiction. MPA and the Ministry of Environment (Ministério do Meio Ambiente, MMA) are jointly responsible for fisheries’ management and scientific assessments, in current days. No harvest strategy is known to be defined for the fishery.
For the multispecies snappers’ fishery since 2005 that log books are mandatory for fishing vessels over 10 tons (Interministerial Normative nº 26/2005). From 2011, only loglines and traps are allowed (Normative nº 10/2011). There are no seasonal closures or other measures to manage the fishery.

RECOVERY PLANS

Last updated on 3 June 2014

No recovery plan is known to be in place.

COMPLIANCE

Last updated on 3 June 2014

The National Plan to Combat Illegal, Unreported and Unregulated Fishing, developed in partnership with different Ministries, was established in December 2013, including awareness campaigns, training and control measures (MMA, 2013). There are no signs of non-compliance.

3.ENVIRONMENT AND BIODIVERSITY

ETP SPECIES

Last updated on 3 June 2014

The impact of the fishery on Protected, Endangered and Threatened (PET) species is not recorded.
The Brazilian Northeast coastal region is an important habitat for Common minke Whale Balaenoptera acutorostrata (Least concern; Reilly et al., 2008) and bottlenose dolphins Tursiops truncatus (Least concern; Hammond et al., 2012); is also a foraging ground and nesting area for olive ridley Lepidochelys olivacea (Vulnerable; Abreu-Grobois and Plotkin, 2013) and loggerhead Caretta caretta (Endangered; MTSG, 1996) (Mattos e Silva et al., undated).

OTHER TARGET AND BYCATCH SPECIES

Last updated on 3 June 2014

Yellowtail snapper is captured in a multispecies fishery, the same of vermillion snapper. Other species are not regularly quantified.

HABITAT

Last updated on 3 June 2014

Impacts of longlines on the seabed ecosystem are not expected to occur.

MARINE RESERVES

Last updated on 3 June 2014

There are some marine reserves in Brazil. None is known to exist in the fishing area with special measures.

This indicates the potential risk of human rights abuses for all fisheries operating within this stock or assessment unit. If there are more than on risk level noted, individual fisheries have different levels. Click on the "Select Scores" drop-down list for your fisheries of interest.

DATA NOTES

Last updated on 3 June 2014

1) Landings 1950-2012 from FAO (2014).
2) Time-series for biomass and fishing mortality are not available.
3) No formal or regular assessment is conducted. Last scientific recommendations (2005) are to reduce fishing mortality. Advised catch limit at 3,500 tons but no related measures were defined. Fishing mortality level estimated by Klippel et al. (2005c) and biomass by Klippel et al. (2005b). Reference points determined were not used because the assessment is considered to be outdated. None of the scores could be determined.
