A recent study reveals that fish aggregating devices (FADs) used in tuna fishing are causing harm to coral reefs and marine wildlife, even in protected areas. Despite fishing bans in these regions, over 1,500 FADs have drifted into marine protected areas globally, impacting vulnerable species. FADs, typically made of wood or bamboo with plastic components, are utilized to catch smaller tropical tuna like skipjack, popularly sold in canned form.

Traditionally, FADs were equipped with nets or ropes to attract fish. However, due to entanglement risks for wildlife, mesh nets were banned in 2025, replaced by ropes only. These floating rafts draw small fish seeking shelter, leading to the aggregation of predator species like tuna for easier capturing by fishing vessels. Each year, approximately 100,000 FADs are released into the ocean, with 90% eventually lost, posing environmental hazards.

When FADs drift into marine protected areas, they can cause extensive damage by stranding on beaches and coral reefs, resulting in plastic pollution. The study documented over 6,000 FAD strandings in 174 protected regions, impacting rare coral species. Furthermore, entanglement incidents involving sharks and turtles have occurred, although reduced since the banning of netting on FADs.

Efforts to address FAD-related environmental issues include promoting sustainability certifications, like the Marine Stewardship Council, which incentivizes fishing companies to adopt eco-friendly practices. Initiatives such as the development of biodegradable FADs and guidelines for responsible deployment aim to reduce the ecological footprint of these devices. Recommendations also include limiting FAD numbers, avoiding release in high-risk areas, and encouraging retrieval by fishing companies.

Collaboration between industry stakeholders, environmental organizations, and ongoing research efforts can help mitigate the adverse impacts of FADs on marine ecosystems. Increased public awareness and pressure for sustainable fishing practices are crucial for driving positive change in the industry, similar to previous successful campaigns addressing environmental concerns.
