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).

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

Africa: widespread in West and central tropical Africa, including most coastal rivers of West Africa from Senegal to Angola: Niger, Volta, Chad, Ogowe, Congo and upper Zambezi Rivers (Ref. 2801, 2914, 3569, 81278, 81637). Absent in the Nile River (Ref. 2801, 2914, 3569, 81278, 81637), the Great Lakes (Ref. 7248, 81637) and the Zambian Congo (Ref. 7248). Also known from the Cunene, Okavango, and Kafue systems (Ref. 7248, 81637). It should be noted that this species seems to prefer upper river courses or small rivers where Hydrocynus are absent or scarce (Ref. 2914, 81278, 81637).

Biology     Glossary (e.g. epibenthic)

Adults occur in most coastal rivers, lakes and swamps (Ref. 3569). Prefer quiet, deep water, like channels and lagoons of large floodplains. Juveniles and fry inhabit well-vegetated marginal habitats. Adults feed on fish, juveniles feed on small invertebrates and fish. Multiple spawner; breeds over the summer months. Relatively short-lived, only 4-5 years; also caught with drawnets (Ref. 7248). An individual of 510 mm SL has been reported from Senegal but not confirmed, and there exists a head in the MNHN from the Cavally that would have belonged to an individual of ca. 700 mm TL and weighing ca. 4000 g (Ref. 81637).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00149 - 0.00887), b=3.16 (2.94 - 3.38), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.8 se; Based on diet studies.
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 to moderate vulnerability (29 of 100) .
