Our Yellowfin Tuna is caught by a select fleet of fishing vessels using FAD Free Purse Seine fishing methods and is therefore better for marine conservation. All Coles Own Brand seafood, whether farmed or wild caught, must meet our responsible sourcing standards. At Coles, responsibly sourced seafood means that the farms and fisheries have been independently certified or assessed to help mitigate potential environmental risks including impacts on surrounding ecosystems, illegal and unregulated fishing, and overfishing of stocks related to seafood sourcing and production of Coles Own Brand product.
