Aquaponics
Aquaponics combines aquaculture with hydroponics and grows fish and plants in a symbiotic balance – with waste from the fish providing nutrients for the plants, which in turn filter the water for the fish.

Aquaponics has a long history in Asia with people growing fish in rice paddies but today it is becoming more sophisticated. There are now systems that work in both indoor and outdoor environments.
