MUNCIE, Ind. (AP): An eastern Indiana county has narrowly approved a fish farm's plans for a feed mill that's part of a $30 million expansion supporters say will help turn the area into an aquaculture hub.

Delaware County's Board of Zoning Appeals approved Bell Aquaculture's expansion plans on Thursday despite complaints by the farm's neighbors that its fish feces lagoon stinks and its water discharges have flooded surrounding property.

The Star Press reports the board's vote had been tied 3-3 until its chairman cast the deciding vote to approve the feed mill, which will produce 2.2 million pounds of fish food a month.

Albany, Ind.-based Bell Aquaculture produces nearly 3 million pounds per year of yellow perch, trout and coho salmon. It touts itself as the nation's largest yellow perch farm.
