The habitats and habitat preferences of the young of the Lake Victoria Tilapia (Pisces-Cichlidae)
1964
Weilcomme, R.L.
The habitats of the Lake Victoria Tilapia species have been, described by Lowe (1956) and FRYER (1961). Although most of their work was done on fish of adult size, both of these workers noted something of the distribution of the fry, attention in particular beingpaid to habitat preferences and possible competition between native and exotic species. Little is known however of the factors, both physical and ecological, at play on the beaches and other parts of the shallow lake littoral which are universally used as a habitat by the young of Tilapia species. Furthermore since the above work was carried out several features have changed in Lake Victoria. The first of these, the rise in lake level, has during 1963 and 1964, submerged orchanged the nature off the lake shore, rendering the papyrus swamp channels mentioned by LOWE (1956) unsuitable as habitats for fry.
