Though Spanish seafood giant Nueva Pescanova is juggling dozens of sustainability goals as part of its "Pescanova Blue" project, the group doesn't see an end in site for its work.

"I don't think there will ever be a deadline, it's a job of continual improvement," Nueva Pescanova Sustainability Manager Angel Matamoro told IntraFish.

The "Pescanova Blue" initiative encompasses a suite of sustainability projects relating to supply, operations, labor relations and development of the communities where the company operates, Matamoro said.
