The farmers at Fyn River Farms near Loveland don’t have much acreage to speak of, and their hired hands don’t even have hands. That’s the way of this aquaponic operation: The field is inside a building, and most of the workers are goldfish who create the nutrients to feed the crops.

Business partners Jason Rider and Mike Bennett have converted a 2,400-square-foot shop building just east of Loveland into an indoor growing operation that they call a farm. The system was ready to go in mid-January, and they are harvesting basil leaves as big as their hands now.
