Thai Union Group and Brazilian seafood business Actemsa are to launch a fishery improvement project for the pole-and-line skipjack, yellowfin and bigeye tuna fishery in the southern and south-eastern coastal areas of the Latin American country.

The companies are working on the project with campaign group WWF. They are aiming for the project to be Marine Stewardship Council-certified.

Beatrix Richards, head of sustainable commodities at WWF’s UK office, said: “This is an important step towards addressing the sustainability concerns around the Brazil tuna fishery. The sustainability of the world’s seafood supply is a critical global issue, not only for the environment but also for human welfare.”

Sylvain Cuperlier, the group CSR and sustainability director for Thai Union’s European operations, said: “This FIP in Brazil comes after two significant FIPs that we announced this year in the Indian Ocean and eastern Atlantic Ocean.”

Fishery improvement projects are being followed to try to make the sourcing of seafood species more sustainable.

José Luis Escuris Villa, Actemsa’s CEO, said it was the first time the company had taken part in such a project. He added: “We believe that sustainable fishing should be a shared responsibility across the entire seafood supply chain, and not just the duty of fishing vessels.”
