Article excerpt

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.

Some fish farms already use the new food recipe, and researchers expect use to spread quickly.

"I'd say within a year or two it should catch on. We're close," said David Sessa, a chemist on the project at the National Center for Agricultural Utilization Research in Peoria.

Illinois is the leading producer of ethanol, a type of alcohol made from corn. Billions of pounds of leftovers are produced every year, Sessa said Thursday. Much goes into feed for cattle and other animals, but not all.
