US supermarket chain Raley’s said Thursday it completed transitioning its fresh seafood offerings to sustainable seafood company-wide six months earlier than planned.

Raley’s now sources its fresh seafood from fisheries or farms with certifications recognized internationally as credible by scientific, industry and non-governmental organizations. Also its vendors must provide documented evidence that products do not come from sources that use illegal methods.

“Sustainable seafood represents a healthy relationship with our planet that can endure forever," said President and COO Keith Knopf.
