Industry Voices 01 features Javier Díaz López, Fleet Director at Grupomar®, on the structural challenge facing Mexico’s tuna fleet: competing from a higher cost base while raising efficiency, quality and market value.
1. From your experience in the Eastern Pacific, what is today the main structural challenge for the Mexican tuna fleet?
“The fishery in the Eastern Pacific is currently experiencing a cycle of abundance. We know these cycles are natural and should not make us forget our obligation to continue improving operational efficiency.”
Javier points to Mexico’s comparatively less competitive cost structure as the underlying challenge. Grupomar’s response is to compensate through greater efficiency, a relatively young Pacific fleet, high vessel operability and disciplined cost management.
The second lever is catch value. Grupomar has invested in onboard freezing systems and changed its operating culture so quality begins at the fishing stage, with the aim of accessing direct-consumption markets that can better value Mexican yellowfin.
He also sees crew knowledge as a genuine competitive advantage: preserving that experience while embedding a stronger culture of quality, sustainability and efficiency is part of the long-term challenge.
2. How are IATTC measures impacting annual operational planning?
“The reduction in closures is a positive signal that fishery management has been responsible. It improves operational flexibility.”
Grupomar’s operation targets large yellowfin and does not rely on FADs. Javier views controls on floating objects as positive for managing fishing effort, while observer requirements are already embedded in Mexican fleet operations.
Planning is increasingly centred on maintenance autonomy and operational agility. Grupomar has strengthened its internal maintenance capabilities to reduce dependence, maintain quality standards and keep vessels available during productive fishing cycles.
3. Where is the greatest room for improvement in efficiency?
“Efficiency must be a culture.”
One Grupomar vessel has been fully monitored as a test bed for fleet digitalization. Condition sensors are now helping the company move toward predictive maintenance by detecting failures before they affect operability, while improved satellite connectivity is expanding what shore teams can see and manage in real time.
4. What weight do sustainability and traceability carry in fleet strategy?
Grupomar has focused on onboard processes, discharge and storage, renewing freezing systems to meet Mexican and European requirements and support direct-consumption exports. Javier describes sustainability as part of the company’s operating DNA after more than four decades in tuna.
The company is working toward recovering MSC certification for Mexican tuna and has launched a Fishery Improvement Project. The objective is to balance environmental performance with an economically sustainable fleet that can continue providing employment and an affordable protein source.
5. Looking five years ahead, what structural change will redefine competitiveness?
Javier remains constructive on the medium-term outlook. Tuna is globally managed through RFMOs, stock conditions remain broadly supportive, and consumption has room to grow in large markets including India and China. Mexico also has an increasingly interesting strategic position because of its proximity to the United States.
His conclusion is clear: if the Mexican fleet continues improving efficiency and quality, it can convert today’s structural challenges into a stronger competitive position.
BIGEYE NEWS — EDITORIAL PERSPECTIVE
The Mexican tuna fleet is entering its next competitive cycle around six structural levers: operational efficiency, fleet modernization, advanced freezing, predictive maintenance, sustainability and market diversification.
What emerges is not a tactical response to one fishing season, but a longer-term repositioning built around creating more value from the same fishing activity.
