(University of Eldoret, 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 ... -
NON-CLASSICAL APPROACHES TO THE STUDY OF THE ECOLOGY AND FISHERY OF Rastrineobola argentea (PELLEGRIN 1904) IN THE WINAM GULF OF LAKE VICTORIA, KENYA
(University of Eldoret, 2013)Many schools of thought tend to suggest that the central assumption in classical fisheries models may not necessarily hold and thus there is need to explore new approaches such as Bayesian Belief Networks (BBN), Artificial ... -
GENDER ROLES IN FISHING LIVELIHOODS: A CASE OF LAKE BARINGO COMMUNITY, BARINGO COUNTY-KENYA
(University of Eldoret, 2015)The role and contribution of the fisheries sub-sector in Kenya’s fishing communities cannot be underestimated. To ensure sustainable fisheries livelihoods, the Government has developed Fisheries Beach Management Units ... -
Aberrationof Metals Competing for Iron on Exposure to Lambda Cyhalothrin and Aflatoxins in Dietary Fish from Selected Aquatic Sources in Kenya
(Food Science and Nutrition Studies, 2018)Excess or deficiency of minerals may seriously disturb biochemical processes and upset internal homeostasis, leading to various diseases and disorders in fish species due to deficiency or excess ... -
Influence of Rainfall Seasonality onEndohelminth Parasites of Oreochromisniloticusbaringoensis (Trewavas, 1983) at River Molo Inlet in Lake Baringo, Rift Valley, Kenya
(Journal of Aquatic Science and Marine Biology, 2018)This study was conducted at the inlet of River Molo in Lake Baringo, Kenya during dry and wet seasons.Dissolved oxygen, temperature, turbidity and pH were measured in-situ.Fish samples collected werepreserved ... -
Growth and Nutrient Removal Efficiency of SweetWormwood (Artemisia annua) in a RecirculatingAquaculture System for Nile Tilapia(Oreochromis niloticus)
(MDPI : Wiley, 2019)The maintenance of optimal water quality for fish production is one of the major challengesin aquaculture. Aquaponic systems can improve the quality of water for fish by removing theundesirable wastes and in turn produce ... -
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 ... -
EFFECTS OF BIOFLOC TECHNOLOGY ON GROWTH PERFORMANCE OF NILE TILAPIA (Oreochromis Niloticus)FINGERLINGS AND MICROBIAL COLONIZATION IN THE SYSTEM.
(International Journal of Agriculture, Environment and Bioresearch, 2018)Aquaculture intensification is characterized by high stocking density and need of high quality and quantity of artificial feed. Increased fish biomass and feed input brings about rapid deterioration ... -
Assessment of theFisheries Status in River Molo to Guide the Management on its Fisheries
(African Journal of Education, Science and Technology, 2018)Rivers provide a suite of ecosystem goods and services to fisheries as well as water that benefit the domestic and industrial use of the riparian communities. The increasing intensification of ... -

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 ... -
Fish assemblages and size-spectra variation among rivers of Lake Victoria Basin, Kenya
(Ecological Indicators, 2020-07)Riverine ecosystems are some of the most biologically diverse on earth, but are also among the most threatened by anthropogenic actions. Lack of local-scale studies monitoring changes in riverine populations makes it ... -
Hippopotamus are distinct from domestic livestock in their resource subsidies to and effects on aquatic ecosystems
(royalsocietypublishing.org/journal/rspb Proc. R. Soc., 2020-03)In many regions of the world, populations of largewildlife have been displaced by livestock, and this may change the functioning of aquatic ecosystems owing to significant differences in the quantity and quality of their ... -
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 ... -
Influence of catchment land use and seasonality on dissolved organic matter composition and ecosystem metabolism in headwater streams of a Kenyan river
(Biogeochemistry An International Journal, 2017-01)Headwater streams influence the biogeochemical characteristics of large rivers and play important roles in regional and global carbon budgets. The combined effects of seasonality and land use change on the biogeochemistry ... -

Are Large Herbivores Vectors of Terrestrial Subsidies for Riverine Food Webs?
(Springer Science+Business Media New York, 2015-03-17)The tropical savannas of Africa have witnessed a dramatic reduction in native large mammalian herbivore populations. The consequences of these changes for terrestrial-aquatic food-web linkages are poorly documented. ... -
Litter processing and shredder distribution as indicators of riparian and catchment influences on ecological health of tropical streams
(Ecological Indicators, 2014-05)Terrestrial plant litter is the main source of energy for food webs in forest headwater streams. Leaf litter quality often changes when native tree species are replaced by exotic ones and land use change in the watershed ... -
Macroinvertebrate functional feeding groups in Kenyan highland streams: evidence for a diverse shredder guild
(The Society for Freshwater Science, 2014-02)Data on the functional composition of invertebrates in tropical streams are needed to develop models of ecosystem functioning and to assess anthropogenic effects on ecological condition. We collected macroinvertebrates ...
