The Sea Has Become a Dumping Ground for Fishing Waste

Hundreds of plastic crates from the fishing industry appearing on the beaches of Puerto Madryn should not be dismissed as a curiosity caused by a storm, or as a problem solved by sending crews to clean the shore. They are the visible sign of a deeper and entirely avoidable environmental crisis.

Plastic pollution on the Chubut coast has an unusual profile. Worldwide, around 80% of the plastic that reaches the ocean is estimated to come from land-based sources. On beaches in protected areas of the province, however, more than 90% of the plastic waste collected comes from the sea and is associated with fishing activity.

Nets, ropes, gloves, buoys and buckets used aboard vessels regularly appear on Patagonia’s beaches. The crates may be the clearest symbol of a problem worsened by the extraordinary expansion of shrimp fishing. Shrimp landings at Chubut’s ports grew from about 50,000 tonnes in 2013 to nearly 185,000 tonnes in 2024. Puerto Madryn and Rawson account for more than 80% of those landings.

It is impossible to link every crate found on a beach to a particular company or vessel. But presenting their accumulation as a mystery makes little sense. Studies by the Whale Conservation Institute and Fundación Vida Silvestre Argentina, carried out through the MaRes Project, identified port operations, fishing areas near the mainland, and routes between ports and fishing grounds as possible points where materials are lost.

What reaches the beach is only the visible part of the problem. Much of the plastic remains in the ocean for decades or centuries. Nets and ropes can trap marine animals, while degrading plastic becomes microplastic that persists in ecosystems and can enter the human body. The problem is especially serious when waste reaches Península Valdés and other exceptionally valuable natural environments. A profitable industry that exploits marine resources should not be allowed to pass the environmental cost of its waste on to society. Rawson has a facility to receive and sort fishing materials, along with training for workers and companies, but the article argues that such efforts remain insufficient. The answer is not better beach cleanups after every storm. It is preventing the waste from reaching the water through proper onboard storage, reception facilities in every port and recovery systems.
