Expanding fish farming, safe capture

We want fisheries everywhere to expand their fish farming businesses and commit to safe capture so we can all enjoy a more sustainable planet. Certifications—like our recently-acquired ASC certificate, given to businesses that responsibly source farmed marine products—are a step in the right direction. But we need to do more. Which is why we develop farming technologies that protect natural marine resources and have one of the world's first egg-to-harvest-raised bluefin tuna farms.
