"Seafood counters used to be simpler places, where a fish was labeled with its name and price. Nowadays, it carries more information than a used-car listing. Where did it swim? Was it farm-raised? Was it ever frozen? How much harm was done to the ocean by fishing it? Many retailers tout the environmental credentials of their seafood, but a growing number of scientists have begun to question whether these certification systems deliver on their promises. The labels give customers a false impression that purchasing certain products helps the ocean more than it really does, some researchers say."
"Backers respond that they are helping transform many of the globe’s wild-caught fisheries, giving them a financial incentive to include environmental safeguards, while giving consumers a sense of what they can eat with a clear conscience.
To add to the confusion, there are a variety of certification labels and guides, prompting retailers to adopt a hybrid approach, relying on multiple seafood rating systems or establishing their own criteria and screening products that way."
