deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 15 - 17; duri punggung lunak (Keseluruhan (total)): 11-14; Duri dubur 3; Sirip dubur lunak: 9 - 12; vertebrata, bertulang belakang: 30 - 32. Diagnosis: 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 (Ref. 2).

Biologi     Daftar kata (contoh epibenthic)

Young Oreochromis mweruensis feed on epiphytic filamentous algae in swampy areas (Ref. 2), but also accept small invertebrates and zooplankton, a tendency they lose with age (Ref. 52307). Adults feed on filamentous algae and detritus (Ref. 52307) and bottom deposits, but those that migrated to the deeper northern end feed almost exclusively on plankton (Ref. 2).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | 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.
