General Description of the Research Project In the Tanzanian part of Lake Victoria, a drastic increase in the population of Nile perch, a large freshwater fish introduced to the lake, has led to an increase in production of fishery resources and establishment of an economic base through commercialization. However, it has also led to catastrophic damage to the lake’s unique ecosystem, which includes species of cichlids, a well-known family of tropical fish. At present, the recovery of this ecosystem is an urgent task. The goal of this study is to establish a comprehensive ecosystem management system that enables both biodiversity conservation in Lake Victoria and sustainable utilization of Nile perch, on which the economic base depends. In collaboration with the Tanzania Fisheries Research Institute (TAFIRI) and the Ministry of Livestock Development and Fisheries, the study will monitor the genetic and ecological diversity of cichlid species that are native to Lake Victoria and of Nile perch, and will use the results of monitoring to present a conservation plan and to regulate catches, with the ultimate goal of promoting conservation policy and sustainable fishery led by the Tanzanian government.
