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

Africa: St. Paul River in Liberia up to the Pra in Ghana, including the rivers St. John, Farmington, Cess/Nipoué, Cavally, San Pedro, Sassandra, Boubo, Bandama, Agnébi, Comoé and Tano Rivers (Ref. 57127). Reports from the Ouémé River in Benin and the Volta basin need confirmation; reports from the Congo basin and Wouri River (Cameroon) are based on misidentified specimens of other species (Ref. 43912).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1. Diagnosis: large species, up to 300 mm SL or more (Ref. 57127). Anterior nostrils never closer to each other than the posterior ones; inner margin of pectoral-fin spine finely denticulate; 39-70 branched anal-fin rays; 8-15 gill rakers on lower limb of first gill arch; adipose fin always present (Ref. 43912, 57127). Lower jaw reaching as far as or a little shorter than upper jaw; brownish longitudinal stripes along sides and anal fin (Ref. 43912).

Biology     Glossary (e.g. epibenthic)

Found in riverine and lacustrine conditions; prefers freshwater but has also been recorded from brackish water lagoons in mixohaline water; voracious and carnivorous (Ref. 43912). Feed mainly on (terrestrial) insects (Ref. 6868, 43912) and fish, but also fruits, amphibians, small rodents and Arachnida have been found in stomachs (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00389 - 0.01070), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.49 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Assuming fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
