Seasonality in environmental conditions drive variation in plankton communities in a shallow tropical lake
(Frontiers in water, 2022)Factors influencing the spatio-temporal dynamics of plankton communities in small tropical lakes are not well-understood. This study assessed plankton communities in response to spatial (six sampling sites) and seasonal ... -
Sediment Heavy Metal Pollution Assessment in Changwang and Wuyuan Rivers in Hainan Island, China
(Water, 2023)Heavy metal pollution may pose a significant threat to aquatic ecosystems. To assess heavy metal pollution, sediment samples were collected from Changwang and Wuyuan Rivers between June and December 2019. An inductively ... -
Shifts in the food of Nile perch (Lates niloticus) in Lake Victoria
(Journal of Lake and Reservoirs, 2018)The study investigated diet of Nile perch in Lake Victoria and compared results with past data from the same lake in order to analyse diet shifts over time. Fish samples (2020) were collected by seining and trawling from ... -
Shifts in the food of Nile perch (Lates niloticus) in Lake Victoria
(John Wiley & Sons Australia, Ltd, 2018-11)The study investigated diet of Nile perch in Lake Victoria and compared results with past data from the same lake in order to analyse diet shifts over time. Fish samples (2020) were collected by seining and trawling from ... -
Some Aspects of Fish Biology and Ecology of River Perkerra in Lake Baringo Basin, Kenya
(Journal of Aquatic and Terrestrial Ecosystems, 2023)Human activities including construction of dams along the river ecosystems may result in ecological changes in the fish and fisheries. This study assessed some aspects of fish biology and ecology of River Perkerra in ... -
Some aspects of reproduction and feeding habits of Nile tilapia (Oreochromis niloticus) in three dams in Uasin Gishu County, Kenya
(Lakes & Reserv, 2019)Knowledge of the fisheries status of dams within Uasin Gishu County was needed prior to the government's plan to introduce fish and fisheries in the area. The dams were constructed in the 1950s and stocked with tilapia ... -
Some biological aspects of the Silurid Catfish, Bagrus docmak (Forksskal, 1775) in Lake Victoria, Kenya
(Journal of Fisheries & Aquaculture, 2021-02)Bagrus docmak is indigenous to Lake Victoria, being an important source of economic livelihoods to communities around the lake. Although its stocks in the lake are facing intense fishing, predation and ecological changes, ... -
SPATIAL VARIABILITY IN WATER QUALITY AND MACROINVERTEBRATE ASSEMBLAGES ACROSS A DISTURBANCE GRADIENT IN THE MARA RIVER BASIN, KENYA
(University of Eldoret, 2021)Across the Afrotropical ecosystems, human activities are increasingly modifying natural flow regimes, nutrient and organic matter loading and processing in streams and rivers, with implications on ecosystem structure and ... -
SPATIAL – TEMPORAL DISTRIBUTION AND ABUNDANCE OF LARVAL STAGES OF NILE PERCH (Lates niloticus LINNAEUS 1758) IN LAKE VICTORIA, KENYA
(2018)Lake Victoria is a relatively dynamic ecosystem with constant changes in both biotic and abiotic variables primarily influenced by human activities. Studies in the ecology and fisheries in Lake Victoria has mostly concentrated ... -

SPATIO-TEMPORAL DYNAMICS OF THE MARINE AQUARIUM FISHERY AND RECRUITMENT OF REEF FISHES IN COASTAL KENYA
(University of Eldoret, 2017)Sustainable management of the marine aquarium fisheries in Kenya is challenged by limited information on the fishery and recruitment dynamics of target species at sufficient spatial, temporal and taxonomic scales. In order ... -
SPATIO-TEMPORAL PATTERNS OF MACROINVERTEBRATE FUNCTIONAL FEEDING GROUPS IN THE SOSIANI-KIPKAREN RIVER, KENYA
(University of Eldoret, 2021)Different land-use practices in river basins affect the hydrological characteristics, water quality and alter the complex biotic and abiotic processes that govern the functioning macroinvertebrate communities. Studies ... -
A STUDY ON GROWTH PERFORMANCE AND VIABILITY OF THREE MARINE FISH SPECIES UNDER CAGE CULTURE IN THE KENYAN COAST
(2016-05-23)This study set out to investigate and compare the growth performance and viabilities of three different marine fish species for commercial cage culture. The study was carried out in Makongeni village along Kenya coast ... -
Suitability of Soybean-Blood Meal Mixture as Replacement of Fish Meal in Nile Tilapia (Oreochromis niloticus) Rations
(African Environmental Review Journal (AER), 2020-12)Fish require high quality protein in their rations which is sourced from fish meal. However, its scarcity and competition for use in livestock feeds has caused escalation of prices thus limiting its use. A study was carried ... -
TROPHIC ECOLOGY AND EXPLOITATION STATUS OF SHARK SPECIES (PISCES: ELASMOBRANCHII) IN THE NORTH COAST OF KENYA
(University of Eldoret, 2017)Sharks are apex predators in marine ecosystems whose trophic ecology is likely to influence community structure and function in their distribution range. Despite this role, data on the trophic ecology and exploitation ... -
Trophic structure of an African savanna river and organic matter inputs by large terrestrial herbivores: A stable isotope approach
(John Wiley & Sons Ltd ; Freshwater Biology., 2018-06). Knowledge of trophic structure is important to understand sources and pathways of energy resources in community ecology and to identify determinants of ecosystem changes. Yet, little is known from rivers of African ... -
Use of macroinvertebrate assemblages for assessing performance of stabilization ponds treating effluents from sugarcane and molasses processing
(Springer, 2017)Wastewater discharge from sugarcane processing is a significant pollutant of tropical aquatic ecosystems. For most developing countries, monitoring of the level of pollutants is done mostly through chemical analysis, but ...
