An investigation by the Environmental Justice Foundation (EJF) exposes Senegal's Port of Dakar as a major gateway for the illegal shark fin trade. 

About Shark Finning

Shark finning is the brutal practice of removing a shark’s fins and discarding the rest of its body back into the ocean, often while the animal is still alive. 

  • Unable to swim, the defenseless shark sinks to the bottom and dies from suffocation, blood loss, or predation.

 

Major Impacts of Shark Finning

Rapid Population Decline: Global shark and ray populations plummet by 71% since 1970 due to intense industrial fishing pressure.

Food Chain Disruption: Eliminating apex predators disrupts nutrient cycling and the "whale pump" mechanism, which suppresses phytoplankton growth and cripples ocean productivity.

Extinction Risks: The International Union for Conservation of Nature (IUCN) warns that 70% of pelagic sharks face extinction, with fishers killing 80 million to 101 million sharks annually.

Biodiversity Loss: Sharks possess a K-selected life history (slow growth, late maturity, low fecundity) and cannot reproduce fast enough to recover, threatening species like the scalloped hammerhead and oceanic whitetip.

Economic Deprivation: Coastal communities lose livelihoods as reef degradation and fish stock collapses damage artisanal fisheries and ecotourism.

IUU Fishing Growth: Shark finning facilitates Illegal, Unreported, and Unregulated (IUU) fishing, allowing tuna longline fleets to conceal bycatch mortalities and bypass international catch quotas.

Organized Crime Escalation: Transnational crime syndicates co-opt the shark fin trade, driving corruption, smuggling, and human rights abuses on unregulated distant-water vessels.

Ecological Importance of Sharks

Apex Predators: Sharks regulate mid-level mesopredator populations, preventing trophic cascades that destabilize the entire marine food web.

Marine Biodiversity: Predators strengthen prey gene pools by targeting sick, weak, and slow-moving individuals, which regulates prey behavior and prevents the overgrazing of vital habitats.

Ocean Health Indicators: Sharks preserve the structural integrity of coral reefs and seagrass beds; for instance, removing sharks in the Caribbean triggered algal blooms that killed healthy coral reefs.

Sustainable Fisheries Support: By balancing the food web, sharks protect commercially important fish stocks, preventing collapses like the century-old scallop fishery collapse on the US East Coast.

Ecotourism Drivers: Live sharks generate substantial long-term revenue through sustainable ecotourism, contributing $38.6 million annually to the Maldives and $42.2 million to Fiji.
