Hawaiian Gold Tilapia, Oreochromis Massambicus, can exceed 16 inches in length as an adult and grows really fast. The Hawaiian Gold Tilapia is known to tolerate temperatues from 60 degrees F to 98 degrees F and are very tolerant when it comes to poor water quality, pollution and oxygen scarity.
Tilapia serves as a natural biological control for most aquatic plant problems. Tilapia consume floating aquatic plants, such as duckweed watermeal, most "undesirable" submerged plants, and most forms of algae.
Tilapia rarely compete with other "pond" fish for food. Instead, because they consume plants and nutrients unused by other fish species and substantially reduce oxygen-depleting detritus, adding tilapia often increases the population, size and health of other fish.
Tilapia are commonly used with Aquaponics. Aquaponics is a sustainable food production system that combines a traditional aquaculture (raising aquatic animals such as fish in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. Freshwater fish are the most common aquatic animal raised using aquaponics. In practice, tilapia are the most popular fish for home and commercial projects that are intended to raise edible fish.
