Short description Morfología | Morfometría

Espinas dorsales (total): 15 - 17; Radios blandos dorsales (total): 11-14; Espinas anales 3; Radios blandos anales: 9 - 12; Vértebra: 30 - 32. Scales on cheek in 2-3 rows. Caudal scales variable, not on the inter-radial membranes except at the base; never stiffening the fin. Genital papilla large and tuberculate or scalloped, tasseled in breeding males. Generally lighter or darker olive-green. Breeding male iridescent dark green to blue-black on head, body and vertical fins; red edge to dorsal and caudal fins.

Young Oreochromis mweruensis feed on epiphytic filamentous algae in swampy areas; adults feed on bottom deposits, but those that migrated to the deeper northern end feed almost exclusively on plankton (Ref. 2).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Spawns along the banks of lakes/rivers at an average depth of 12 to 13 m. Mating territory largely occupied by a low mound with 6-12 grooves or crests radiating from the small central concave area (star-shaped nest). Males build the star-shaped nests on a sandy substrates.
