Jesse David Merton Schwartz. The functional role of fish diversity in Lake Victoria, East Africa. Submitted in partial fulfilment of the requirements for the degree of Doctor of philosophy. Boston University Graduate school of Arts and Sciences. Anonymous. Anonymous. 2002. Lake victoria , the world's largest tropical lake is home and provides livelihood to millions of East Africans.Historically it contained 500+ species of indigenous fishes,most of which were haplochromine cichilds.The 1959-60 introduction of the predatory fish Nile perch(lates niloticus),coupled with other sources of environmental degradation,caused the extinction of hundreds of cichild species.The resultant L.niloticus fishery,now the world's largest freshwater fishery,gained popularity as a food and revenue source for the East African nations,often overshadowing concerns regarding cichild conservation.This study examined functional roles of fish diversiy in Lake Victoria using field,laboratory,and modelling techniques.I hypothesized that fish diversity was related to community function. |

In the laboratory i found that Nile perch captured cichilds (haplochromis "ruby") more easily than schooling cyprinids (Brachydanio rerio) at several predator and prey densities.Increased expenditures in active matebolism,such as increased feeding costs,can negatively impact growth.I related dietary correlated changes in Nile perch growth to changes in activity and consumption using bioenergetics model.The loss of cichilds from the Nile Perch diet may affect activity and consumption,with varying consequences for growth efficienct. |

The effects of fish diversity on system throughput were investigated using a dynamic mass-balance model.Haplochromine stock sizes impacted total system detritivory and phytoplanktivory.The restoration of cichild diversity may benefit system function. |

Metabolic variance was described in two cichild species(xystichromis phystophagus and pyxichromis orthostoma) and their F2 hybrid.For the hybrid,standard metabolic rates and surface to volume ratios of digestive and respiratory organs were intermediate of the parentals.Metabolic diversity may be heritable and can govern the potential functional roles of cichilds. |

Fish communities were studied in the lake Kyoga system in central Uganda.The system contains diverse pristine cichild lakes and disturbed Nile perch lakes.Stable nitrogen isotopic signatures suggested that Nile perch have altered foods webs in the Kyoga system much like they have in Lake Victoria.The Kyoga satellite system represents a natural experiment for further investigating the functional role of fish diversity in lake Victoria.

Pamela J. Schofield. Feeding ecology of the introduced Nile perch (Lates niloticus) in Lake Nabugabo, Uganda : implications for conservation of the indigenous fauna. Anonymous. Anonymous. 1997. The introduction of the predatory Nile Perch (Lates niloticus) into the lake Victoria basin coincided with a dramatic decline in fish species richness and diversity.This study focussed on interactions between nile Perch and indigenous fishes in lake Nabugabo,Ugand,a small (24km2 ) satellite of lake victoria.I evaluated how the foraging impact of Nile perch on prey fishes varied with the size of the predator and the role of wetland ecotones in minimizing interaction between nile perch and indigenous fishes.
