The tilapia is a large fish of African origin which has gradually spread throughout the tropical and sub tropical regions of the world. It grows accustomed to new habitats well and its resistance is absolutely incredible. Because of its ability to become used to different habitats and, above all, for its food value to populations lacking protein, the tilapia has been introduced into many areas both voluntarily and involuntarily. Tilapia can reach up to 45 cm (18 inches) in length and weigh approximately 2 kg (1 pound). They will feed on anything from table scraps to algae and plankton.
The tilapia is a mouth brooder, which means that their fertilized eggs are collected into the mouth of the female. First, the male scoops out a small depression on the bottom and the eggs are deposited and fertilized there. The female then takes them into her mouth and incubates them for about three weeks. As the eggs hatch, they move out of the mouth and swarm over the head of the parent. The school of fry follows the parent around and will flee into its mouth if alarmed, until they can swim away independently. The tilapia have 6 to 11 egg laying cycles per year.
