The challenge

Protecting Argentina’s seabed from bottom trawling, which is destroying habitats and preventing the recovery of fish species.  

Our strategy

Blue Marine supports local NGO Rewilding Argentina in its mission to protect 30 per cent of the waters of Chubut province in Patagonia from bottom-trawling and other threats, and ultimately to protect 30 per cent of the country’s Exclusive Economic Zone.Other partners include: Por La Mer, SeaLegacy, Patagonia Azul and Patagonia Projects.  Advocacy campaigns have raised national awareness about the threat of industrial fishing and promoted MPAs as the solution.  

 

 

Our impact

  • Initiative to establish a 450 km marine park 
  • Strong 10-year collaboration formalised with Chubut provincial government  
  • First ever open-access vessel registry   
  • Rewilding Argentina aims to create an MPA of more than 100,000 sq km 
  • Announcement of the creation of Patagonia Azul Provincial Park, a marine sanctuary spanning 729,000 acres. This park draws a protective blue line around over 60 islands and islets, kelp forests and rugged coastal habitats.  

Work in the field

In 2025 , our partners achieved significant victories along the Patagonian coast, crowned by the creation of the Patagonia Azul Provincial Park. A marine protected area (MPA) of 295,135 hectares, it now safeguards migratory routes for whales, feeding grounds for seabirds, and the country’s largest colony of South American fur seal. 

The province of Chubut also granted legal protection to seven species, including humpback and sei whales, Commerson’s dolphins, the white-headed steamer duck, the southern giant petrel, and the broadnose sevengill shark. 

These protections were strengthened by studies that identified dozens of new humpback whales, documented their presence across new seasons, recorded more than 29 weeks of whale vocalizations and revealed the long-distance travels of fur seals. Research teams also expanded live camera networks that now stream the daily lives of penguins, shags, and petrels.
