Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Characiformes (Characins) > Hepsetidae (African pikes)
Etymology: Hepsetus: Greek, epsetas, -e, -on = boiled, but there is the following sentence: "oí epsetoi" = certain fishes, and also could be related to "psetta" = grouper (Ref. 45335).

Environment / Climate / Range Ecology

Freshwater; demersal; pH range: 6.0 - 7.5; dH range: ? - 18; potamodromous (Ref. 51243).   Tropical; 26°C - 28°C (Ref. 2060)

Length at first maturity / Size / Weight / Age

Maturity: Lm 14.0  range ? - ? cm
Max length : 27.8 cm SL male/unsexed; (Ref. 88135)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9; Anal spines: 0; Anal soft rays: 12. Diagnosis: distinguished from all other Hepsetus species by the following unique combination of characters: number of lateral line scales low, 43–51; nostril-lower jaw distance short, 36.6–42.1 (mean 39.6)%HL; number of gill rakers high, 17–23; number of scales between dorsal fin and lateral line 7.5-9.5; number of scales between adipose fin and lateral line 4.5-6.5; head width broad, 32.8–42.3 (mean 37.0)%HL; internasal distance high, 21.9–28.3 (mean 24.7)%HL (Ref. 88135).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: from the Sassandra River (Ivory Coast) in the west to the Shari River (Central African Republic) in the east, and southwards up to the Kribi/Kienke River (Cameroon)(Ref. 88135). Reports from outside this area refer to other Hepsetus species (Ref. 88135, 93279, 93907).

Biology     Glossary (e.g. epibenthic)

Seems to prefer upper river courses or small rivers where Hydrocynus are absent or scarce (Ref. 2914, 81278, 81637). Adults occur in most coastal rivers, lakes and swamps (Ref. 3569).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00161 - 0.00896), b=3.15 (2.94 - 3.36), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.71 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.27-0.59; tmax=5; Fec < 10,000).
Vulnerability (Ref. 59153):  Low vulnerability (16 of 100) .
