What is both aquaculture and aquaponics?

Answer 1

Aquaculture is raising aquatic living things, usually fish and usually for food.

Aquaponics includes an aquaculture system, but adds raising vegetables hydroponically to it. Hydroponics is a system of raising vegetables without soil, but with nutrient-laden water. The term aquaponics is a combination of aquaculture with hydroponics.

In aquaculture, it is important to deal with the fish waste. In aquaponics, the way to deal with fish waste is to convert it into nutrients for plants, which remove if from the water, so the water can be returned to the fish.
