Africa: lakes Edward, George, Kyoga, Victoria, Nakavali and Kachira, and the rivers and streams associated with these lakes, including the Semliki (Ref. 5602, 126033, 126038). It has been introduced into many areas of East Africa for biological mollusc control and now has a widespread distribution within the Victoria basin in Kenya, Uganda and Tanzania, including the upper Akagera basin in the Bugesera Depression in Burundi and Rwanda (Ref. 126033). Also introduced in Benue River basin in northern Cameroon (Ref. 126033). However, there are no reports that its introduction in Congo Republic, Democratic Republic of Congo, Republic of Central Africa and Zambia has succeeded (Ref. 126033).

Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 16 - 20; Raios dorsais moles (total) : 6 - 9; Espinhos anais: 4 - 7; Raios anais moles: 6 - 9. Diagnosis: Astatoreochromis alluaudi can be distinguished from A. straeleni by the possession of 4-7 anal spines vs. 3-4, and 17-19 dorsal spines, rarely 16 or 20, vs. 16-18, exceptionally 19 (Ref. 126033).

Biologia     Glossário (ex. epibenthic)

Astatoreochromis alluaudi is not confined to a particular type of substrate and is ubiquitous in all areas where the water is less than 20 m deep; it also occurs in papyrus swamps (Ref. 5602, 126033). It feeds mainly on molluscs (Ref. 126033), but it might be an omnivorous species that switches to the most abundant food source in its environment (Ref. 6770, 126033). Used for snail control (Ref.4967).

Life cycle and mating behavior Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

This species is a mouth-brooder (Ref. 126033). Though its breeding period is not well documented, the species may reproduce at the end of the short rain season from November to December (Ref. 126033).
