Seafood Watch–whose guidelines are gospel to the sustainable seafood crowd–announced its support for a new salmon-farming technique, the first it has ever endorsed. Most fish farms raise salmon in vast ocean net pens; the fish can escape and spread disease to wild populations. But at AquaSeed Corp., an aquaculture company based in Rochester, Washington, salmon are bred to be kept in freshwater tanks on land, which reduces pollution and the spread of sea lice and other maladies. The fish receive special feed, requiring less wild-caught fishmeal than the salmon at traditional farms. Furthermore, their meat contains plentiful omega-3 fatty acids and low enough levels of PCBs to land it squarely–cue the heavenly chorus!—on the Seafood Watch’s “Best Choices” and “Super Green” lists.
