Supermarkets are tightening the net on farmed seafood products as demand for environmentally-friendly products grows, reports the Washington Post. Aquaculture now supplies more than half of America's rising demand for fish and shrimp and retailers are working with producers and green groups to make sure the farmed products are both safe and sustainable.
Whole Foods plans to announce a comprehensive set of standards today. The retailer, with support from the industry and the World Wildlife Fund, aims to ensure fish food stays free of dangerous additives, and that aquaculture doesn't damage sensitive wetlands. "There are actually a lot of farmers right now who are trying to do the right thing," a WWF spokeswoman said. "Things are moving in the right direction."
