Oreochromis aureus, Sarotherodon aurea, Tilapia aurea, Isreali tialpia, or
commonly known as the Blue Tilapia is a species of fish in the Cichlidae family.
The Tilapia is the most popular fish species used in Aquaponics due to their
ability to easily breed, fast growing, and can withstand various
water conditions. Tilapia is also the most popular fish for home and commercial
projects that are intended to raise edible fish. Aquaponics is a sustainable
food production system that combines a traditional aquaculture ( aising aqatic
animals such as fish in tanks) with hydroponics (cultivating plantsw in water)
in a symbiotic environment. They can feed on algae or any plant-based food,
which makes them important in aquaculture. Blue Tilapia work great in aquaponics
systems as they serve as a natural biological control for most aquatic plant
Blue Tilapia begin to spawn when water temperatures reach 68°F and above.
Tilapia are mouth brooders which means the female will collect the eggs in her
mouth to maintain them until hatching. Brood sizes can range from 100-2000 eggs,
depending on the size of the female.
The Blue Tilapia is a freshwater fish with a high tolerance for brackish
and colder water. Adults are usually 10-18 inches in length and can weigh 2-6
pounds. The largest Blue Tilapia was 21 inches and weighted just over 9
pounds! Optimal temperatures range of 60-86°F with max temperatures ranging
Tilapia primarily feed on plankton, detritus on the bottom of the tank, and
vegetation such as duckweed, water hyacinth, and algae to name a few.
