- Pascale Moehrle, who led Oceana’s European office from 2019 to 2025, spent more than four decades working on wildlife conservation and ocean policy.
- Her death was announced by Oceana on March 4, 2026.
- Moehrle pushed European governments to follow scientific advice on fisheries, curb destructive fishing practices and enforce protections in marine protected areas.
- Her work focused on turning Europe’s commitments on ocean protection into practical policy that could restore marine ecosystems and sustain fisheries.
In recent decades Europe’s seas have become a test of whether environmental policy can keep pace with ecological decline. Scientific advice on fisheries has grown more precise, satellite monitoring has expanded, and governments have pledged to restore marine ecosystems. Yet many fish stocks remain under strain, and destructive fishing practices continue in areas meant to protect biodiversity. The gap between commitments and outcomes has become a familiar feature of marine policy.
Environmental groups have tried to narrow that gap by translating scientific findings into political pressure. Their work often takes place in committee rooms, regulatory consultations and court filings rather than at sea. Success depends on persistence: years spent arguing for tighter catch limits, enforcement of existing rules, or the protection of habitats that are easily damaged but slow to recover.
Among the figures who devoted much of their professional life to that effort was Pascale Moehrle, executive director and vice-president of Oceana in Europe from 2019 to 2025. Her death was announced by Oceana on March 4th, 2026.
Over a career in conservation that began in the early 1980s, Moehrle became a prominent voice urging European governments to manage fisheries more cautiously and to treat marine ecosystems as core environmental policy instead of peripheral to it.
When Moehrle assumed leadership of Oceana’s European office, debates over fisheries and marine protection were intensifying across the European Union. Scientific assessments had long warned that many fish stocks were under pressure, and that destructive fishing practices were damaging seabed habitats. The political response, however, often lagged behind the science. Moehrle focused much of her effort on turning those commitments into enforceable rules. She pressed governments to follow scientific catch limits, reduce harmful subsidies and strengthen enforcement in marine protected areas.
She tended to argue the point plainly in her writing. Marine reserves, she noted on several occasions, should not remain “lines on a map.” Protection had to be real, and it had to be enforced. In European waters this meant confronting practices such as bottom trawling, in which heavy nets are dragged along the seabed. The method remained widespread even inside some protected areas. Moehrle repeatedly argued that allowing destructive fishing in zones set aside for conservation undermined both environmental policy and confidence in marine protection rules.
She also pressed policymakers to consider the broader ecological consequences of fishing. In commentaries and policy interventions she warned that the impact of fisheries on climate change extended beyond fuel consumption by vessels. Techniques that disturb seabed sediments can release stored carbon and weaken the ocean’s role in regulating the climate. Addressing emissions from the fishing fleet, she argued, would do little if the ecological effects of fishing itself were ignored.
Moehrle joined Oceana’s European office in 2017 as chief operating officer, overseeing the organization’s programmes and operations across several countries. Two years later she became its executive director and vice-president in Europe. The role required balancing advocacy with diplomacy. Oceana’s campaigns combined scientific research, legal challenges and public pressure aimed at national governments and European institutions.
Her interest in conservation dated to the early 1980s. She later recalled beginning her career alongside campaigners in Asia and the Pacific who were working to protect endangered species and support the livelihoods of local communities. Those experiences convinced her that environmental protection and human welfare were closely linked, a view that shaped her later work on fisheries policy.
Much of Moehrle’s advocacy centered on the tension between short-term economic pressures and the long-term health of marine ecosystems. Fisheries support large numbers of jobs and remain politically sensitive in coastal regions. For Moehrle the point was not to end fishing but to make it durable. Fish populations, she argued, would recover if governments followed scientific advice and reduced pressure on depleted stocks.
Her final public interventions retained the same theme. In early 2025 she warned that continued delays in implementing existing fisheries rules risked pushing European seas toward the more pessimistic scenarios already described by scientists. The tools to prevent that outcome, she said, already existed. What remained uncertain was whether governments would use them in time.
