Etymology: Astatoreochromis: Greek, astato = unstable + Greek, rheos = stream + Greek, chromis = a marine fish without identification, dealing with perch; cited by Plinius (Ref. 45335)alluaudi: Named after Charles A. Alluaud, who collected the type specimens (Ref. 126033).
Eponymy: Charles A Alluaud (1861–1949) was a French entomologist, botanist and naturalist who came from a wealthy family, living in a chateau where the painter Corot was a frequent visitor. [...] (Ref. 128868), visit book page.

Verspreiding Gebieden | FAO regio's | Ecosystemen | Voorkomen | Verspreidingskaart | Introducties | Faunafri

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).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 16 - 20; Dorsale zachte stralen (totaal) : 6 - 9; Anale stekels: 4 - 7; Anale zachte stralen: 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).


Body shape (shape guide): fusiform / normal; Cross section: oval.

Biologie     Verklarende woordenlijst (bv. 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).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

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).
