In Casey Huling’s class, “Why Food Matters,” students built an aquaponics setup. If “hydroponics” is growing vegetables in water, and “aquaculture” is raising fish, then “aquaponics” combines both in a symbiotic system. Aquaponics uses the waste that fish produce to feed plants. In our setup the fish waste is pumped into hoses that have drip spouts so that the water will drip onto the plants in PVC pipes (shown above). The plants take all the nutrients they need from the water and the clean water goes back into the fish tank. The solid waste from the fish is saved and will be dried to use as fertilizer.
