“…The introduction of piscivorous Nile perch in the 1950s, which was intended to increase the economic value of Lake Victoria's fisheries, led to significant declines in native haplochromine cichlids (previously about 500 species), which also supported significant subsistence fisheries in the three bordering countries (Uganda, Tanzania, and Kenya). The catchment basin for Lake Victoria has one of the highest population densities in Africa (~500 people per km 2 ), and fishing is one of the few sources of livelihood for local communities (Ogutu-Ohwayo et al, 2020). There is a need to better understand the trade-offs among economic (fisheries profits), social (employment), and conservation (ecosystem structure and resilience) objectives in order to develop effective fisheries policies, though limited resources to support data collection, modelling, and fisheries governance and enforcement have hindered resource management efforts (Musinguzi et al, 2017).…”
