When it comes to the food used to raise fish in aquaculture "farms," it seems that you may get what you pay for. In a new study, researchers from the National Institute of Standards and Technology (NIST) and the South Carolina Department of Natural Resources (SCDNR) looked at the health effects of raising farmed fish on a diet incorporating less than the usual amount of fishmeal—a key but expensive component of current commercial fish food products. They learned that reduced fishmeal diets may be cheaper, but the fish were less healthy.
