Aquaponics

At NW Tilapia, there is a harmony that resides between our Tilapia and our plants. This "harmony" is called Aquaponics.

Aquaponics is a sustainable food production system that combines a traditional aquaculture (raising aquatic animals) with hydroponics (cultivating plants in water) in a symbiotic environment. In this system, effluents, such as ammonia and nitrates, accumulate in the water, increasing toxicity for the fish. This water is led to a hydroponic system where the by-products from the aquaculture are filtered out by the plants as vital nutrients, after which the cleansed water is recirculated back to the aquatic animals.

Growing Healthy Vegetables

NW Tilapia uses the benefits of the nitrate rich waters, from the grow-out fish production, to feed beds of lettuce, herbs, and other crops. Unlike chemical fertilizers, the nitrates in the water are in the most richest, natural form possible. A head of lettuce, in ideal climate and sunlight, can grow from a transplant to a full head of lettuce in 3-4 weeks. Below are some photos of our crops.
