Cameroon country information

Common names: Pungu
Occurrence: endemic
Salinity: freshwater
Abundance: | Ref:
Importance: | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: live export: yes;
Comments: Known only from Lake Barombi Mbo (Ref. 52307, 81260), a crater lake in the rainforest; not recorded from inflow or outflow streams; this species is under threat due to overfishing and other socio-economic factors, the introduction of alien species (crustaceans and fishes), siltation and a reduction or loss of the allochthonous food supply of terrestrial plant material and invertebrates (both resulting from local deforestation), adverse water level fluctuation and water pollution (Ref. 26185). Also Ref. 3881, 13614, 51193, 53940, 58527. Wrongly labelled as from Lake Barombi-ba-Kotto in original description (Ref. 53940).

Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 15 - 17; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8 - 9; Ryggkotor: 29. Diagnosis: mouth terminal (Ref. 26185, 53940). Distinctive fleshy lips (Ref. 26185, 52307), from which protrude rows of outwardly directed jaw teeth (Ref. 26185, 53949). Inner jaw teeth usually with 3 subequal cusps, outer row notched in juveniles but with simple replacements in adults (Ref. 26185, 53940). 7-8 lower outer teeth, 12-23 upper outer teeth; blade and dentigerous area of lower pharyngeal bone subequal, with slender teeth, firm and unicuspid posteriorly; colour variable, often silver-yellow (pale or intense) with dusky mottling concentrated on head and, to a lesser extent, midline (Ref. 26185). No Tilapia-spot on dorsal fin (Ref. 26185, 52307, 53940, 53949). Metallic blue highlights on operculum, dorsal and caudal fins (Ref. 26185).

Biologi     Ordlista (t.ex. epibenthic)

Usually found in smaller groups (Ref. 52307) in shallow waters of lake shore (<4 m deep)(Ref. 26185). Feeds mainly on benthic invertebrates (mayfly, caddis and chironomid midge larvae) (Ref. 26185) and the endemic sponge Corvospongilla thysi (Ref. 53950, 58527, 81260), but diatoms and terrestrial macrophytes are also sometimes eaten in quantity (Ref. 26185). Maternal (Ref. 52307) mouthbrooder (Ref. 13614, 52307, 58527).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Eggs green (Ref. 26185, 53940, 58527) and ovoid, large (4x3mm) and few in number (Ref. 26185, 53940). Female is mouthbrooding (Ref. 13614), but possibly variable biparental mouthbrooder (variably one of the parents or both incubate eggs)(Ref. 58527).
