Description
The longfin tilapia is a robust cichlid of the family Cichlidae reaching about 43 cm. The deep, laterally compressed, silvery-grey body has a long dorsal fin; the breeding male develops elongated front dorsal-fin rays and a blue-yellow glow. It is a maternal mouthbrooder: the male digs a large spawning pit on a shallow bottom, and after mating the female broods the fertilised eggs in her mouth. As a plant-eater it feeds mainly on phytoplankton, algae, water plants and detritus. The species comes from south-central Africa, including the Zambezi and Congo basins, and has been stocked elsewhere for fish farming. Through overfishing and displacement by introduced tilapias it has declined in parts of its range; the IUCN assesses it as Vulnerable (VU).
