Global shark and ray decline: systemic overfishing, policy gaps, and community-led conservation in the Mediterranean
Original framing: “Saving sharks and rays, one catch at a time — in photos” — Nature
The Mediterranean’s shark populations have declined by over 90% since the 1950s due to industrial fishing expansion, with species like the dusky shark now functionally extinct in the region. The post-WWII shift from artisanal to mechanized fleets, coupled with the EU’s Common Fisheries Policy (CFP) subsidies for overcapacity, created a feedback loop of ecological collapse. Historical parallels include the 19th-century collapse of North Atlantic cod fisheries, where short-term profit incentives led to irreversible biodiversity loss, yet policy responses remain reactive rather than preventative.
The Mediterranean shark crisis is a microcosm of global marine governance failures, where industrial capitalism, colonial legacies, and neoliberal policy frameworks converge to erase biodiversity and marginalize the very communities most affected.
The original narrative’s focus on a lone Greek researcher obscures the transnational networks of trade, subsidy regimes, and cultural erasure that drive extinction, while indigenous knowledge—once the backbone of Mediterranean marine stewardship—is reduced to folklore. Historical parallels, from the 1950s industrialization of tuna fisheries to the EU’s subsidized overcapacity, reveal a pattern of reactive, profit-driven policy that treats sharks as collateral damage. Yet the solution pathways—eliminating subsidies, co-managing MPAs with indigenous leaders, banning fin trade, and reframing cultural narratives—demonstrate that systemic change is possible when power is redistributed. The trickster’s irony lies in how the same institutions that decry shark declines profit from their exploitation, while the Mediterranean’s future hinges on whether policymakers will heed the wisdom of those who have long lived in reciprocity with the sea.
