Occurs in both river and swamp habitats (Refs. 2, 6465). Hardy, tolerating fresh and brackish water (up to 20ppt, Ref. 3), preferring slow-flowing or standing water (Refs. 7248, 12524, 13337, 52193) with some weed cover (Refs. 12524, 13337). Adults occupy deep open waters (Refs. 7248, 12524, 13337, 52193), juveniles remain inshore among vegetation (Refs. 7248, 52193). Hippo pools are a favoured retreat (Refs. 12524, 13337). Forms schools (Refs. 2, 12524, 13337). Mainly diurnal; a detritivore which feeds on fine particulate matter (Ref. 2), including algae (Refs. 246, 12524, 13337, 53992), diatoms, detritus (Ref. 7248, 52193, 53992) and zooplankton (Refs. 7248, 52193). Larger individuals also take insects and other invertebrates (Ref. 53992). Feeding regime is variable, the diet changes according to food availability (Ref. 6465).

Life Cycle
(
Inglês
)
fornecido por Fishbase
Spawning did not occur in ponds at a temperature below 21°C (Ref. 2). Rarely more than one brood in a season (Ref. 87, 246), but known to breed at least twice a year under pond conditions (Ref. 12524, 13337). Males excavate saucer-shaped nests (Ref. 246, 314, 6465, 12524, 13337, 54048) that can be up to 75cm in diameter and 30cm deep, using mouth and fins (Ref. 2, 314, 52307), in the center of their territory (Ref. 52307), on a sandy substrate (any vegetation is uprooted with its mouth) and in water from 1-3m deep, where they display to attract females (Ref. 12524, 13337, 54048). Up to 40 nests can be found together (Ref. 6465). Females are the primary care-givers (Ref. 52307), moutbrooding eggs, larvae and fry; multiple broods are raised during the warmer months (Ref. 7248, 52193). She lays her eggs in the concavity on top of the nest, the male fertilizes the eggs whereupon the female takes the eggs into her mouth where they are incubated; males guard the nest and females against all intruders; parental care is exercised for the first few weeks after the eggs hatch (Ref. 12524, 13337).

Diagnosis: male genital papilla bluntly conical with a narrow flange slightly notched in the middle; jaws enlarged in breeding males, which in this species are normally not less than 30cm TL; scales in lateral line series 31-35, usually 32-33; scales of cheek in 3 full rows; vertebrae 30-32; total number of dorsal rays 28-31. Pectoral fin in adults 34-43% SL (Ref. 2), very long (Ref. 1904). Depth of body 40.5-50.5% SL; color-pattern of non-breeding fish and female always including 3 or 4 conspicuous mid-lateral blotches and a red margin on dorsal and caudal fins; breeding male with red margins broader and brighter and general dark, iridescent purplish-brown color of head, back and flanks, masking the blotches; no series of vertical spots or vertical stripes on caudal fin; nest a simple circular depression (Ref. 2).Description: deep bodied (Ref. 12524, 13337, 52307, 54048) with a straight profile (Ref. 1887, 2989, 6465, 12524, 13337, 52307, 54048). Snout rounded (Ref. 1887, 2989). Small mouth (Ref. 12524, 13337, 13400), extending to between nostril and eye (Ref. 2989). Lower pharyngeal bone slender (Ref. 54096). Teeth slender, not densely crowded (Ref. 2, 54096), the posterior with a marked second cusp or shoulder; inferior vertebral apophysis only on third vertebra; microbranchiospines present on the outer sides of arches 2 to 4; 5-8 scales between bases of pectoral and pelvic fins; caudal fin only scaled at the base (Ref. 2). Caudal fin with 15 rays (Ref. 1904). Adult large males have the posterior rays of the dorsal fin prolonged (Ref. 12524, 13337). Pectoral fin reaching vertical of origin of anal; pelvic fin reaching between vent and anal; caudal fin rounded; scales cycloid (Ref. 1887, 2989).Coloration: body silvery-grey with upper parts of head and body darker than ventral parts (Ref. 2, 52307). Dorsal fin light green to brown Ref. 12524, 13337). Pectoral (Ref. 1904, 12524, 13337) and pelvic fins light grey (Ref. 1904) to green; anal fin grey to green at its base (Ref. 12524, 13337). Margins of dorsal and anal fin bright red (Ref. 2, 6465, 7248, 12524, 13337, 52193, 52307). Soft portions of dorsal and anal fins with pale tips and dots (Ref. 2, 1887, 1904, 2989, 6465, 7248, 52193) that are also sometimes visible in the caudal fin (Ref. 2, 52307). 3 prominent black spots present on flanks (Ref. 2, 1887, 2989, 6465, 12524, 13337, 54048) and a black patch on the posterior portion of the gill cover (Ref. 2, 1887, 2989, 12524, 13337, 54048). The 3 body spots are usually visible from an early age (Ref. 12524, 13337), and are more pronounced in small specimens (Ref. 6465).

Driekolkurper
(

)
fornecido por wikipedia AF
Die Driekolkurper (Oreochromis andersonii) is 'n varswatervis wat in die boonste gedeelte van die Zambezirivier, die Kunenerivier, die Okavangorivier en Kafuerivier voorkom. In Engels staan die vis bekend as die Threespot tilapia.
Voorkoms
Die onvolwasse vis is silwerig met 8-9 onreëlmatige dun strepe op die lyf en daar is 3-4 kolle in die middel van die lyf. Die volwasse visse is blougrys en die skubbe se rante is lig wat die vis 'n blokkiesvoorkoms gee. Die vinne is ook blougrys en daar is kolletjies op die sagte deel van die dorsale- en analevinne. Die rante van die dorsale- en analevinne is helderrooi.
Broeiende mannetjies is blouswart met 'n silwerige blokkiesvorm en 'n rooi skynsel op die bokant van die kop. Die buiterante van die dorsale- en stertvin is helderrooi.
Die vis word tot 50 cm lank en kan tot 3.2 kg weeg. Die Suid-Afrikaanse hengelrekord is 1.97 kg en die Zimbabwe-rekord is 3.09 kg.
Habitat
Die vis is gehard en leef in vars en brakwater maar verkies stadigvloeiende water of staande water soos in poele en vloedvlaktes. Die volwasse visse leef in dieper water terwyl die onvolwasse visse langs die oewers bly tussen die plantegroei. Hulle vreet detritus, diatome en soöplankton. Die mannetjies maak 'n groot pieringvormige nes en die wyfie mondbroei die eiers en larwes. Die vis kan meer as een keer broei gedurende die warm maande. Die vis word ook gebruik in akwakultuur.

Oreochromis andersonii, the three-spotted tilapia, threespot tilapia, or threespot bream, is a species of cichlid native to Africa, where it is found in rivers and swamps in the southern half of the continent. This species reaches a length of 61 cm (24 in). It is important to local commercial fisheries, as well as being commercially farmed. It is also popular as a gamefish.[2] The identity of the person honoured in the specific name of this fish is not known but it is though most likely to be the Swedish explorer and hunter Charles John Andersson (1827-1867) who explored much of Namibia where the type was collected.[3]

Kolmitäplätilapia
(
Finlandês
)
fornecido por wikipedia FI
Kolmitäplätilapia (Oreochromis andersonii) on tilapioihin kuuluva kirjoahven, jota tavataan eteläisen Afrikan joissa. Laji kasvaa maksimissaan 61 senttimetriä pitkäksi ja 4,7 kilogramman painoiseksi. Laji luokitellaan vaarantuneeksi.
Ulkonäkö ja koko
Sukukypsyyden kolmitäplätilapia saavuttaa 12–15 senttimetriä pitkänä, ja lajin maksimipituus on 61 senttimetriä ja maksimipaino 4,7 kilogrammaa. Sekä koiraalla että naaralla on lisääntymiskauden ulkopuolella 3 tai 4 selvää täplää keskivartalossa ja punaiset reunat selkä- ja peräevässä. Lisääntymisaikana koiraiden evien punaiset reunat ovat leveämmät ja kirkkaammat. Lisäksi koiraan päässä, selässä ja kyltissä erottuu kimalteleva ruskean sinipunerva.[2]
Levinneisyys ja elinympäristö
Kolmitäplätilapia elää Sambesin yläjuoksulla sekä Kafue-, Okavango- ja Cunenejoissa. Se on melko yleinen sekä Sambesissa että Okavangossa.[1]
Aikusia yksilöitä tavataan pääasiassa syvemmissä lammissa ja jokien pääuomissa. Poikasia tavataan sen sijaan useamassa elinympäristöissä, kuten tulvatasankojen laguuneissa, suurissa avoimissa soissa sekä harvoin jokien pienemmissä sivujoissa.[1]
Kolmitäplätilapian yksilömäärä on laskussa, ja Kansainvälinen luonnonsuojeluliitto luokittelee sen vaarantuneeksi. Suurimman uhan sille asettaa mahdollinen niilintilapian leviäminen, joka on aiheuttanut jo muutamian muiden tilapialajien sukupuuton.[1]

Oreochromis andersonii est une espèce de poisson de la famille des cichlidae et de l'ordre des perciformes. Cette espèce est endémique de l'Afrique. Il fait partie des nombreuses espèces regroupées sous le nom de Tilapia.
Répartition géographique
Cette espèce est endémique de l'Afrique. On la rencontre dans le bassin Ngami, la rivière Okavango, la rivière Cunene et Mossamedes en Angola, le Zambèze supérieure, le fleuve Kafue, le milieu du Zambèze, le lac Kariba et le bassin de Cabora (depuis la construction de barrages). Plusieurs pays signalent l'impact écologique néfaste après leur introduction. Rapporté tel que présenté dans le parc national de Kasanka (bassin supérieur du fleuve Congo) en Zambie[2].
