We learn about new ways of growing our food. There's aquaculture; growing fish and crops in coastal waters and the open ocean. At the mouth of the Piscataqua River, a UNH-led team has designed a raft that serves as a pen for steelhead trout, with mussels and sea kelp that benefit from the fish. Then there's aquaponics - using the wastewater from farming fish to provide nutrients for plants grown without soil. And then, we hear Peter Biello's interview with Joshua Johnson of 1A when he visited New Hampshire last month.
