Africa: widely distributed in West Africa, where it is known from most hydrographic basins, from the Senegal to the Chad basins, including the West African coastal rivers and the middle and lower parts of the Chad basin (Ref. 53405, 123791). Also in the Nile basin (Ref. 5644, 28714) and in the upper Zambezi (Ref. 5644). Distribution of this species and overlap with Hemichromis elongatus unclear, but probably absent from the Congo basin (see also Ref. 43352, 52307, 53405, 81260). Introduced around 1970 in a stream fed by hot springs in Villach (Austria) (Ref. 59043).

簡単な記述 検索表 | 形態学 | 形態計測学

背面の脊椎 (合計) : 13 - 15; 背鰭 (合計) : 11 - 14; 肛門の骨: 3; 臀鰭: 8 - 11. Diagnosis: With 5 dark blotches or cross bars on sides, often alternating with narrower intercalary bars, the first blotch confluent with the opercular spot, the fifth on caudal-fin base; upper profile of snout straight or concave (Ref. 53405). Hemichromis fasciatus can be distinguished from H. elongatus by the small black dots between the first three dark stripes on the flanks of the body of adults in most populations; it can further be distinguished from H. elongatus by a combination of overlapping morphometrics, mainly by: a high number of anal fin soft rays, 8-11 vs. 7-10; number of longitudinal line scales, 29-32 vs. 28-30; number of lower lateral line scales, 10-14 vs. 8-12; a short snout, 27.2-35.2% of head length vs. 27.4-36.4%; short premaxillary pedicel length, 38-49.7% of head length vs. 38.0-51.2%; short head length, 33.1-38.7% of standard length vs. 34.2-40.3%; short predorsal distance, 32.7-39.6% of standard length vs. 34.3-41.3%; short prepectoral distance, 32.9-40.3% of standard length vs. 35.1-42.3%; short prepelvic distance, 35.4-45.3% of standard length vs. 38.2-48.1%; Hemichromis fasciatus is distributed in West Africa while H. elongatus occurs in the southern part of Lower Guinea and the Congo basin in Cameroon (Ref. 123791).

生物学     用語集 (例 epibenthic)

Found in both forest and savannah biotopes (Ref. 5644); present in littoral riverine habitats and permanent floodplain lagoons with clear water. It feeds on shrimps, small fishes (Ref. 52307) and insects. The species controls large swaths of territory, even larger than those controlled by Hemichromis elongatus; breeding is similar to Hemichromis elongatus (Ref. 52307). A nesting substrate spawner which breeds in the early summer. Pair-bonding well defined (Ref. 52307). Used for tilapia control (Ref. 4537). Maximum TL was recorded at 26.5 cm.

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

Introduced individuals in Austria reported to form pairs during spawning. Female deposits eggs on exposed hard surfaces such as stones or wood. Both parents guard larvae and juveniles for 4-8 weeks (Ref. 59043).
