The Global Mahi Supply Chain Roundtable (SR) was formed in 2019, as an expansion of the previous Eastern Pacific Ocean Large Pelagics Fisheries SR.  

Mahi-mahi, also known as dolphinfish, is a migratory pelagic species that is highly resilient to fishing, due to its rapid growth and early maturation. However, despite this high productivity, many regions of the world have reached their maximum levels of capture and are beginning to see decreases in levels of production. Mahi-mahi is found in tropic and subtropic waters worldwide. Although it is highly desired by sport fishers, most of the production comes from artisanal fisheries, which represent an important source of income for fishers, but also present specific challenges related to sustainable management. Most mahi-mahi fisheries face issues with stock structure, monitoring, control, and surveillance, as well as proper data recording and reporting. In addition, there is a lack of management measures at national and regional levels, low observer coverage, and interactions with sea turtles and sharks.  

The Global Mahi SR will focus mainly on mahi-mahi fisheries, but will also monitor other large pelagic FIPs in the Eastern Pacific Ocean. 

As described in the mahi T75 report, 59 percent of global mahi volumes are currently considered sustainable or improving.  An additional 15 percent of global production could achieve the sustainable or improving categories by 2020 via engagement through the existing supply chain roundtable (SR). To achieve this goal, SR work would need to focus on the following actions:

  • Encouraging producers and key vendors to engage in existing FIPs, to ensure national coverage of improvement efforts in key countries (Costa Rica, Ecuador, Indonesia, and Peru)
  • Requesting national delegates to the Inter-American Tropical Tuna Commission (IATTC) to advocate for the adoption of improvements in science and management in mahi fisheries at the regional fisheries management organization (RFMO) level
  • Encouraging FIP implementers and key vendors in the IATTC region to coordinate efforts to enhance regional impact at the RFMO level
  • Providing support to new and current FIPs.

Current Fisheries and/or FIPs Covered: The SR focuses on global coverage of mahi-mahi fisheries and will monitor other large pelagic FIPs in the Eastern Pacific Ocean. The scope of this SR includes promoting FIPs at a national level to ensure improvements in fishing policies and practices, advocating for improvements in regional policies to achieve sustainability goals, and engaging key national vendors on sustainability goals. 

The following FIPs are supported and monitored:

Ecuador Mahi-Mahi FIP (World Wildlife Fund)
Guatemala Pacific Mahi-Mahi FIP (CeDePesca - inactive)
Panama Pacific Mahi-Mahi and Yellowfin Tuna FIP (inactive)
Peru Mahi-Mahi FIP (Confremar - inactive)
Peru Mahi-Mahi FIP (World Wildlife Fund)
Taiwan Hsin-Kang Mahi - Mahi - Longline FIP

The SR prioritizes the following fisheries for the initiation of FIPs:

PROSPECTIVE Costa Rica large pelagics - longline
Ecuador pole and line tuna
Ecuador longline swordfish

Improvement Needs and Recommendations:

1.     Formalizing unregulated fleets, to contribute to ending IUU fishing.

2.     Conducting conventional stock assessments and adopting biological reference points and harvest control rules for mahi-mahi and key bycatch species (e.g., sharks, billfish).

3.     Mandatory and standardized data collection and observers programs with a minimum coverage of 20 percent of the longline fishing operations, to document bycatch and discards of ETP species, including sharks, turtles, and other non-target species.

4.     Control of fishing mortality to maintain the stocks at or above MSY, or to recover the biomass to desired levels for any overexploited stocks.

5.     Industry-recognized adoption of changes to fishing practices to minimize the bycatch and mortality rates of ETP species, such as those outlined in this document (Best practices in tuna longline fisheries report).

6.     Encouraging producers and key vendors to engage in existing FIPs to ensure national coverage of improvement efforts in key countries (Costa Rica, Ecuador, and Peru) and encouraging FIP implementers to coordinate efforts to enhance regional impact at the IATTC level. 

Current Objectives and Action Recommendations for Suppliers:

1.     Communicate with national governments about the need for policy improvement. 

  • There is a lack of biological and fisheries data from mahi-mahi fisheries, due to deficiencies in data collection and data analysis.
  • The current requirement for onboard observer coverage for the longline fleet is five percent. This coverage is too low and lacks compliance.

2.     Communicate to the Inter-American Tropical Tuna Commission (IATTC) about the need for improved management measures, including:

  • Analyze existing knowledge about the stock status of mahi-mahi in the Eastern Pacific Ocean and design and implement a research program aimed at addressing knowledge gaps about the stock(s) structure.
  • Include data from all countries in the next mahi stock assessment and incorporate environmental variables.
  • Formally adopt biological reference points and harvest control rules for mahi-mahi.
  • Increase longline observer coverage to a minimum of 20 percent.
  • Declare mahi to be a prioritized species and approve the Strategic Scientific Plan presented at the 9th Meeting of the Scientific Advisory Committee.
  • Maintain training activities for captains on the handling of bycatch species on board, to ensure they are returned to the sea alive.
  • Prioritize work to assess the effectiveness of adopted and alternative bycatch mitigation methods.
  • Implement a prohibition on the use of steel leaders to reduce shark bycatch, during a period of three consecutive months from April through September of each year for the relevant portions of their national fleets.
  • Analyze the impact of fish aggregating devices (FADs) on mahi stocks and the enforcement of the FAD decisions adopted by the IATTC. Also, review the existing FAD resolutions to see if they are adequate to prevent the depletion of the mahi-mahi stocks.

3.     Request that your suppliers implement the following improvements (as applicable) included in various documents published by SFP on procurement specifications and fishing best practices:

  • Put pressure on governments to take action on formalizing the unregulated fleet, in order to end IUU fishing.
  • Engage in existing ongoing FIPs.
  • Coordinate efforts to enhance regional impact at the RFMO level.
  • For mitigating bycatch in longline fisheries, adopt hook sizes and shapes designed for reducing the catch of turtles.
  • Avoid the use of wire leaders and adopt longer leaders to reduce post-hooking mortality of turtles.
  • Set scaring lines for birds.
  • Strengthen current finning ban by requiring “fins naturally attached” policy to be formally adopted by IATTC.

Quarterly EPO Large Pelagics SR Update – January to March 2019 (Future updates to come under Global Mahi SR name)

This briefing provides an update on progress, activities, and news in the areas of interest to the SR. It also indicates any actions and further support needed. A full summary of past progress, including details from past quarterly updates, can be found here.

1.     Improvements in Target 75 Priority Fisheries

Please find an overview of fisheries identified in the T75 Sector Report, including those currently not necessarily prioritized by the SR, here.

Costa Rica Longline YFT, Swordfish, and Mahi FIP:

Update: The final workplan and budget was presented to the national authorities, who approved the plan and committed to support it. A specific Costa Rica event to launch the FIP and the Platform’s Action Plan took place at the Boston Seafood Show. Upload to Fishery Progress is a work in progress.Chefs Trading is a strategic partner in this FIP.

No further support needed.

Ecuador Pole and Line FIP:

Update: The Ecuador Pole and Line FIP was presented at the SFP T75 Global forum (link).

Further support needed: SR participants to specify their quality requirements (e.g. product size, handling during and after catch) to the FIP.

Ecuador Industrial Longline Swordfish FIP:

Update: No further developments. 

Further support needed: Support the FIP initiation and refer your supply chain to this initiative.

2. Support to Established FIPs and Improvement Efforts

Please find an overview of all existing FIPs and improvement efforts, their current progress rating, and status here.

Update: The following FIPs have been suspended or are inactive and will need support from the SR for their reactivation:

  • Guatemala mahi-mahi, suspended
  • Panama mahi-mahi, suspended
  • Peru mahi-mahi – longline (Confremar), inactive
  • Peru Pacific swordfish – longline, declared inactive in June 2018  

It is necessary to establish a national mahi-mahi FIP in Indonesia. The country produces around 9,000 tonnesof mahi-mahi (9.4 percent of global production), and achieving T75 for this sector will require sustainable management of Indonesian production. 

Further support needed: Contact the FIP implementers and confirm your interest in the FIP making and publicly reporting good progress.

3. Support for Mitigation of Overarching Fishery/FIP Sustainability issues

SR members agreed on the following SR action points: a) supporting the implementation of a regional strategy to encourage their suppliers to participate in an International Mahi Committee, b) requesting the IATTC, through their national delegates, to support the Mahi Committee requests, and c) continuing to support current FIPs and the new FIPs. 

Relevant News: A regional group of mahi producers and processors from Costa Rica, Ecuador, and Peru called COREMAHI has been formed, and has prepared a position statement to their delegates in order to align the state delegates’ agendas with the sustainability requirements of the fishery. This statement includes requests for the IATTC to take further steps toward conducting the needed research to build appropriate management of mahi-mahi.  

Retailers and supply chain partners received historical and updated information on the IATTC’s work on the management of mahi at the IATTC level.

A regional strategy to close the T75 gap and promote policy change at the IATTC level was presented during the SR meeting in Boston in March 2019. The SR will focus in 2019 on supporting existing and emerging mahi-mahi fishery improvements in Latin America, namely in Costa Rica, Ecuador, and Peru, ensuring that they cover the full national production; re-activating any suspended FIPs with industry support (Guatemala, Panama); and beginning to explore and confirm interest in improvements in Indonesian mahi-mahi fisheries. In parallel the SR will focus on mahi-mahi related improvement needs at the IATTC level and engage in support of those needs with national delegates and COREMAHI, and in RFMO meetings.

Further support needed: SR participants to sign a letter supporting the COREMAHIposition statement at the IATTC Scientific Advisory Committee meeting in May.

SR participants to agree on financial support for the T75 strategy.

4. Expansion of the SR

Update: Fortune International became a new formal participant in the SR.

Further support needed: The SR is seeking further participation from mahi-mahi buyers.
