Aquaponics is the cultivation of plants and aquatic animals in a re-circulating environment. A combination of aquaculture and hyrdoponics, aquaponics pairs fish and plant in one integrated system. At Herring Gut, Nile tilapia, a commonly aquacultured freshwater fish, are grown in tanks. The tilapia produce waste containing ammonia, which through a natural bacterial process is converted to nitrite and then nitrate. The plants in our greenhouse (primarily lettuce and basil) take up the nitrate, grow, and clean the water which is circulated back into the fish tanks.
