Peru Mahi

FIP Stage: 4 (Improvements in Fishing Practices or Fishery Management)
Last Updated: October 24, 2016

The Peruvian mahi mahi fishery includes over 4,200 fishermen and is one of the country’s most important artisanal fisheries. Worldwide, Peru is known as the leading international mahi mahi producer. A critical issue challenging this fishery is the lack of effective national and international management needed to address the highly migratory nature of mahi mahi. The fishery also needs additional data on how fishing interacts with other species including endangered sea turtles and sharks. The active involvement of FIP Stakeholders, such as IMARPE (Peruvian Institute of the Sea), and FIP Participants drives improvements against the Marine Stewardship Council standard.

FIP efforts address governance, fishing practices, and environmental impacts of the fishery so that it can meet the MSC standard. This work is steered by FIP Participants and FIP stakeholders and includes:
  • Training Peruvian fishermen to improve data collection through the regular use of logbooks

  • Working with the Ministry of Production to encourage artisanal fishermen to obtain fishing licenses in order to address the issue of 70 percent of the artisanal mahi mahi fleet being unregistered

  • Reducing illegal fishing by designing a traceability system for Peruvian mahi mahi that meets MSC Chain of Custody requirements and WWF’s Traceability Principles

  • Working to reduce sea turtle mortality in the mahi mahi fishery by training fishermen to better handle and release turtles entangled in fishing gear

  • Working with the Inter-American Tropical Tuna Commission scientists and other fishing countries in the Eastern Pacific Ocean to complete a regional mahi mahi stock assessment and reach agreement on international measures to better manage mahi mahi.


We encourage action across the supply chain to support FIP progress. A FIP Participant is an industry member that is part of the seafood supply chain for the FIP product and is actively engaged in supporting the FIP.

The Marine Stewardship Council uses 28 performance indicators to assess the sustainability of fisheries. The chart represents the percentage of indicators that would likely pass, pass with conditions for improvement, or fail upon the fishery’s full assessment.

Engaging Industry to Advance Mahi Mahi Sustainability
March 18, 2017

US businesses are backing Peru’s mahi mahi fishery in a big way. The Peruvian government recently received a letter from 26 major US-based seafood buyers and importers pledging their support for the Peruvian mahi mahi fishery improvement project and urged officials to actively participate in the advancement of the fishery toward the Marine Stewardship Council standard.
