Aquaponics
Aquaponics is an expanding field that combines aquaculture and hydroponic systems to raise fish (or another aquatic organism) and terrestrial plants (e.g., produce, cannabis, landscaping plants). These operations typically use a recirculating aquaculture system (RAS) with fish being raised in the tanks and the water flows from the tanks to an area that collects some of the larger particles in settling tank. The water then continues to raceways or another structure where the plants are being raised. The plants often float in these raceways on trays or at least have their roots extending down into the water, which is where they absorb their nutrients. The excess nutrients (e.g., nitrogen and phosphorous) in the water produced from the fish waste and food are absorbed by the plants, reducing their need for additional fertilizers. The water is circulated from the plants back to the fish tanks and generally needs minimal adjustment or filtration to be suitable for the health of the fish. This efficient system allows for large quantities of plant production in a controlled environment. Many operations rely on the sale of the plants rather than the fish since the quantity of the fish tends to be smaller. In New York, there are a few of these operations that are smaller in scale and part of community gardening organizations, but one larger operation is commercially raising hemp and cannabis.
