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, ... -
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 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 ...
