“…The park is home to around 400 bird species, including large colonies of lesser ( Phoeniconaias minor ) and greater ( Phoenicopterus roseus ) flamingos (McClanahan et al., 1996; Ogutu et al., 2017). The park hosts a diverse array of over 70 mammalian species, including grazers such as hippopotamus ( Hippopotamus amphibius ), waterbuck ( Kobus ellipsiprymnus ), Thompson's gazelles ( Eudorcas thomsonii ), Bohor reedbuck ( Redunca redunca ), Burchell's zebras ( Equus quagga ), warthogs ( Phacochoerus africanus ) and impala ( Aepyceros melampus ) along the lake's shoreline.…”

The activity budget of giraffe in various African populations has been studied extensively, revealing that it is affected by body size, foraging patterns, and sex. Foraging patterns show an animal's feeding choices in its environment and are influenced by resource availability, competition, and predation risk. The ability of giraffe to survive and reproduce is significantly impacted by the variation in activity budget and foraging across different ecosystems. Our study focused on evaluating the seasonal activity budgets and foraging patterns of Nubian giraffe in Lake Nakuru National Park, Kenya. We used the scan sampling method to record the activity budget of giraffe which included foraging, movement, resting, and drinking water. We then evaluated if activities varied with the seasons. A total of 11,280 activities were documented, with 4560 (40.4%) occurring during the dry season and 6720 (59.6%) during the wet season. Foraging accounted for 53% of the time budget during the dry season, but increased to 57% during the wet season. There was a slight drop in records of movement (22%; n = 995 of 4560) and resting (25%; n = 1145 of 4560) from the dry season to the wet season (20%; n = 1375 out of 6720 and 22%; n = 1515 of 6720). During the dry season, females (53%) foraged longer than males (47%), whereas males (44%) had longer resting periods than females (56%). Giraffe frequently fed on Vachellia xanthophloea (67%; n = 4136 of 6215 foraging records), Maytenus senegalensis (19%), and Solanum incanum (9%) over both seasons. Overall, seasons had little impact on giraffe activity time budgets and foraging patterns in Lake Nakuru National Park. A better insight into the behavioural patterns of this subspecies will allow managers to enhance the protection and conservation of the species and its habitat. Heavy foraging on Vachellia by giraffe at LNNP has been associated with a population decline in number, so perhaps planting more of this species in LNNP could promote a rebound in numbers.

“…In addition to overfishing and the impact of invasive Nile perch on indigenous fish species, it is important to note that the ecosystem of Lake Victoria has undergone significant changes in recent decades (Kudhongania et al 1996;Njiru et al 2000). These changes include but are not limited to, the invasion of water hyacinth (Harley 1990;Njiru et al 2000;Van der Knaap et al 2002), the introduction of non-native fish species (Taabu-Munyaho et al 2016;Ogari 2000), and environmental degradation (Hecky and Bungenyi 1992;Harper and Mavuti 1996). These factors have impacted mormyrid populations and their habitats, emphasizing the importance of conservation efforts for their long-term survival.…”

The presence of the non-native Nile perch (Lates niloticus) in Lake Victoria and the resulting ecological transformations have garnered significant attention from the scientific community. However, details regarding the timing, origin, and purpose of the fish introduction have remained elusive. This paper reviews fish fauna changes in Lake Victoria, investigates causes, and advocates for biodiversity conservation through diversity and sanctuary sites. It examines different historical periods to understand changes and guide effective conservation strategies. The introduction of Nile perch has led to a substantial decline and even extinction of many native fish species, particularly cichlids, resulting in ecological imbalances and economic challenges for local fishing communities. To address these pressing issues, ongoing conservation efforts are being implemented. These initiatives focus on promoting sustainable fishing practices, safeguarding critical habitats, and reintroducing native fish species. Furthermore, cage fish farming is being explored as a potential solution to alleviate pressure on wild populations, as suggested by various authors. Recommendations stemming from this study include conducting virtual population analysis for stock assessments of indigenous species, intensify conservation efforts, diversify fishing practices, expand cage fish farming, increase public awareness and education, and enhance policy and governance frameworks. By implementing these recommendations, there is optimism for the recovery and resilience of indigenous fish species in Lake Victoria, leading to the conservation of biodiversity and the promotion of sustainable livelihoods for local communities.
