The Black Tilapia is a freshwater fish with a high tolerance tobrackish (slightly salty) water. Adults are usually 5 to 8 inches in lengthand weigh 1-2 pounds. Black Tilapia aremouthbrooders, and broods range from 160 to 1600 eggs per female.
Tilapia serves as a natural biological control for most aquatic plant problems. Tilapia consume floating aquatic plants, such asduckweed 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 sustainablefood production system that combines a traditionalaquaculture (raisingaquatic animals such asfish in tanks) withhydroponics (cultivating plants in water) in asymbiotic 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
