In recent years the ichthyofauna of Lake Victoria, the world's largest tropical lake, has gone through dramatic changes. The population of Nile perch, a large predator which has been introduced into the lake by man, increased explosively at the expense of many haplochromine cichlid species. At the same time, numbers of a small cyprinid (dagaa) rose sharply.Previously Pied Kingfishers on Lake Victoria fed mainly on haplochromines. Only the youngest nestlings depended on dagaa as primary food… 
The catfish fauna of Lake Victoria after the Nile perch upsurge
TLDR
Of the two largest species, Clarias gariepinus and Bagrus docmak, juveniles disappeared faster than adults, indicates that predation by Nile perch may have played an important role in their decline, and the importance of catfishes for the fisheries in the lake is currently negligible.

The pelagic cyprinid dagaa plays a crucial role in the disrupted ecosystem of Lake Victoria. It is the main utilizer of zooplankton, a major prey for the introduced Nile perch and, after Nile perch,
On the feeding ecology of the pied kingfisher, Ceryle rudis at Lake Nokoué, Benin. Is there competition with fishermen ?
TLDR
The similarity between the diet of kingfishers and fish available on the local market between midFebruary to mid-May 1999, during a low water level period, is considered.
Diel vertical migration of major fish-species in Lake Victoria, East Africa
Understanding of migration patterns is essential in the interpretation of hydro-acoustic stock assessment data of partly demersal partly pelagic fish stocks. In this paper we provide this kind of
The Shrimp Caridina nilotica in Lake Victoria (East Africa), Before and After the Nile Perch Increase
TLDR
Rough estimates of the biomass of predators on shrimps before and after the Nile perch upsurge indicate a reduced predation pressure on juvenileShrimps, while the disappearance of the haplochromines may have released competition with small Nile perCh for juvenile shrimp, thus enhancing the recruitment of Nile per ch.
Life history change in response to fishing and an introduced predator in the East African cyprinid Rastrineobola argentea
TLDR
Overall, introduced Nile perch and fishing tended to be associated with a suite of life history responses in R. argentea, including: decreased body size, maturation at smaller sizes, and increased reproductive effort (larger eggs; and higher relative fecundity, clutch volume, and ovary weight).
Status of the Major Commercial Fish Stocks and Proposed Species-specific Management Plans for Lake Victoria
The fishery of Lake Victoria is dominated by four species, the introduced Nile perch (Lates niloticus) and Nile tilapia, (Oreochromis niloticus), the native dagaa, (Rastrineobola argentea) and
Little evidence for morphological change in a resilient endemic species following the introduction of a novel predator
TLDR
Testing whether the introduction of the piscivorous Nile perch into East Africa's Lake Victoria coincided with morphological change in one resilient native prey species, the cyprinid fish Rastrineobola argentea, found no clear evidence of predator‐associated change in body shape over time.
Food niche segregation between the Malachite Kingfisher, Alcedo cristata, and the Pied Kingfisher, Ceryle rudis, at Lake Nokoué, Bénin
TLDR
Pied Kingfishers feed on a wider diversity of prey, and take larger fish, so that the dietary overlap between the species is relatively low (O = 0.181).

TLDR
The Nile perch, Lates niloticus, a large, voracious predator which was introduced into these lakes about the middle of the century along with several tilapiine species, is thought to have caused the reduction in the stocks of several species.
Species Extinction and Concomitant Ecological Changes in Lake Victoria
TLDR
The decline of the haplochromine species is described and it is demonstrated that the rate and sequence of their decline was determined by their relative abundance, their adult size and their habitat overlap with Nile perch.
Effects of changes in fish populations in Lake Victoria on the food of otters (Lutra maculicollis Schinz and Aonyx capensis Lichtenstein)
TLDR
Observations were made on feeding by spotted-necked otters, and the Cape clawless otter, in Lake Victoria, Tanzania, and a method is described for estimating prey size from the diameter offish eye-lenses found in the otters' faeces.
Ecological segregation in zooplanktivorous haplochromine species (Pisces : Cichlidae) from Lake Victoria
TLDR
This paper deals with zooplanktivorous species from the Mwanza Gulf of Lake Victoria that showed a large overlap in gross morphological characteristics, and finds strong evidence that the species were ecologically segregated to a great extent.
Taxonomy, ecology and fishery of Lake Victoria haplochromine trophic groups
TLDR
Based on ecological and morphological features, the 300 or more haplochromine cichlid species of Lake Victoria are classified into fifteen (sub)trophic groups, mainly based on external morphological characters, which include Nile perch upsurge, and a key to the trophic groups is presented.

TLDR
It is argued that-originating from a skewed sex ratio and breeding in colonies-this adaptation evolved through the combined effects of individual and kin selection.
