Commonly known as the Nile perch, this huge, ravenous fish, introduced into Lake Victoria in the 1950 ’ s, has proved to be an ecological disaster. Within 40 years it has managed to devour nearly half of the lake’s 400 indigenous fish species.
See suur ja ablas kala, keda tuntakse enamasti niiluse ahvenana, toodi Victoria järve 1950 - ndatel aastatel ning see on põhjustanud ökoloogilise katastroofi. 40 aastaga on ta hävitanud peaaegu pooled järve 400 kohalikust kalaliigist.
