Summary

IDENTIFICATION

SCIENTIFIC NAME

Coryphaena hippurus

SPECIES NAME(S)

Common dolphinfish, Mahi-mahi

The best available scientific information indicates there is a single stock of mahi mahi in the Atlantic, U.S. Caribbean, and Gulf of Mexico (Mahon and Mahon, 1987; Wingrove, 2000; South Atlantic Fishery Management Council, 2003), contrary to a previous hypothesis of there being two separate Northern and Southern Atlantic stocks (Oxenford and Hunte, 1986).


ANALYSIS

Strengths

There is a regional fishery management organization (RFMO) in charge of mahi mahi populations in the Atlantic (International Commission for the Conservation of Atlantic Tuna).

Weaknesses

There is not enough information available to conduct a full stock assessment of mahi mahi. There are no management measures in place. Observer coverage rates are low (5%) in longline fisheries targeting mahi mahi in the Atlantic Ocean.

1. Encourage the Gulf of Mexico Fishery Management Council to add mahi mahi back into their management plans.
2. Encourage the US to conduct a stock assessment on mahi mahi.
3. Monitor and report interactions with protected, endangered and threatened species and other bycatch.

RETAILERS & SUPPLY CHAIN

. This profile is not currently at the top of our priority list for development/update, and we can’t at this time provide an accurate prediction of when it will be developed. To speed up an evaluation of the sustainability status of non-prioritized fisheries we have initiated a program whereby industry can directly contract SFP-approved analysts to develop a FishSource profile on a fishery. More information on this External Contributor Program is available at http://www.sustainablefish.org/fisheries-information.

1. Contact the South Atlantic Fishery Management Council (SAFMC) and encourage the SAFMC to conduct a stock assessment of mahi mahi through the SouthEast Data, Assessment, and Review (SEDAR) process.
2. Contact SFP to learn more about how you can initiate a fishery improvement projects (FIPs) or Supplier Roundtable (SRs) for this fishery.

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 16 July 2015

There are very few scientific studies, coupled with inadequate collection of adequate catch and fishing effort data to conduct reliable stock assessments for this stock in the Atlantic Ocean (Oxenford 1999)(ICAAT 2012). There is only one stock assessment reported for this stock in Southeast U.S. waters, with its results being highly uncertain due to absence of reliable data in many sectors for many years. Mahi mahi are caught in multiple gears and significant improvements in catch data are required before the status of the stock can be ascertained throughout its area of distribution.(ICCAT 2012) The range of distribution for this species ranges from George’s Bank in Canada to Rio de Janeiro in Brazil (SAFMC 2003). A more recent stock assessment in the Caribbean failed to provide reliable status of the stock due to data limitations and missing data (Parker et al. 2006).

Scientific Advice

Last updated on 16 July 2015

There is currently no scientific advice on management measures for mahi mahi in the Atlantic Ocean; other than to increase data collection.

Reference Points

Last updated on 16 July 2015

The status of mahi mahi has not been assessed against any reference points.

Current Status

Last updated on 16 July 2015

The current status of mahi mahi in the Atlantic Ocean is unknown.

Trends

Last updated on 17 November 2012

Such data is not available for Mahi Mahi stocks in the Atlantic Ocean.

2.MANAGEMENT QUALITY

Managers' Decisions

Last updated on 16 July 2015

There are currently no international management measures in place for mahi mahi caught in the Atlantic Ocean.

Recovery Plans

Last updated on 17 November 2012

None are reported for this stock in the Atlantic Ocean.

Compliance

Last updated on 16 July 2015

There is no total allowable catch or quota limits in place for mahi mahi caught in the Atlantic Ocean.

3.ENVIRONMENT AND BIODIVERSITY

Habitat

Last updated on 14 December 2011

Pelagic gears used to target Dolphinfish do not come in contact with seafloor and hence have nominal effects on the habitat.

FishSource Scores

MANAGEMENT QUALITY

As calculated for 2015 data.

The score is < 6.

The management strategy is assessed to not be precautionary because the regional fisheries management organization has not adopted a total allowable catch or equivalent limit reference point.

As calculated for 2015 data.

The score is ≥ 6.

There is no set TAC for this fishery; however, no scientific advice suggesting a TAC is needed has been provided.

As calculated for 2015 data.

The score is < 6.

A lack of data (i.e. catch and effort) has prohibited a full stock assessment of this species.

STOCK HEALTH:

HUMAN RIGHTS ABUSE RISK

High Medium Low

This indicates the potential risk of human rights abuses within this fishery.
