In this March 9, 2012 photo provided by the City of Chicago, 312 Aquaponics partner Arash Amini, center, explains the operation to Chicago Mayor Rahm Emanuel, right, and Alderman Pat Dowell in Chicago. The business, which is still awaiting various city licenses, is in a former meat-packing plant in the city's Back of the Yards neighborhood. The plan is to sell greens and fish to restaurants and markets as some growers in Wisconsin are already doing. (AP Photo/City of Chicago, Brooke Collins) less
