Researchers are turning leftovers into fish food and simultaneously helping corn farmers, ethanol producers and fish farmers.
The leftovers are what remains when corn has been turned into ethanol - coarse, brown, smelly materials that often are thrown away. But the materials contain protein, and researchers have come up with a recipe for turning it into fish food.
