(University of Eldoret, 2013)Crimson jobfish, Pristipomoides filamentosus is a commercially important tropical snapper. Their aggressive nature and relatively large size makes them more vulnerable to fishing gears. In addition it is vulnerable to ... -
IMPACT OF LAND USE CHANGE IN WATER QUALITIES, HABITAT QUALITIES AND BENTHIC MACROINVERTEBRATES ASSEMBLEGES IN KIPSINENDE RIVER, LAKE VICTORIA BASIN, KENYA
(University of Eldoret, 2021)Kipsinende River is being impacted by anthropogenic activities from upstream to downstream. The main pollution sources are agricultural activities, washing, bathing, logging, deforestation and grazing. The main objective ... -
INFLUENCE OF HIPPO AND CATTLE DUNG ON THE NUTRIENT LEVELS, ALGAL DIVERSITY, COMPOSITION, BIOMASS AND ECOSYSTEM METABOLISM IN AQUATIC ECOSYSTEMS: A MESOCOSM APPROACH
(University of Eldoret, 2023-07)Large mammalian herbivores (LMH) are major agents of the movement of terrestrial organic matter and nutrients into aquatic ecosystems, which can alter the structure and functioning of aquatic ecosystems. Populations of ... -
INFLUENCE OF LAND-USE ON LEAF LITTER DECOMPOSITION IN HEADWATER STREAMS OF THE NZOIA RIVER, KENYA
(University of Eldoret, 2021)Land-use plays a crucial role in affecting river function, particularly leaf litter decomposition. The study was aimed to investigate the influence of land-use on leaf litter decomposition in headwater streams of the Nzoia ... -
Influence of net cages on water quality and trophic status of Lake Victoria, Kenya: The case of Kadimu Bay
(Wiley Journals, 2023-03)Water quality is a critical component regulating ecosystem functioning in aquatic habitats, requiring regular monitoring for sustainable ecosystem services. Cage fish farming has the potential to affect water quality ... -
THE INFLUENCE OF SALTWORKS’ WASTE-BRINE ON DISTRIBUTION OF MANGROVE CRABS (DECAPODA, PORTUNIDAE) WITHIN THE GONGONI-KURAWA INTERTIDAL AREA, KENYA
(University of Eldoret, 2017)Evaporation is one of the oldest methods employed in sea salt production, a process that involves pumping seas water into a series of ponds where solar evaporation concentrates it into brine, and precipitates the salt; ... -
INTEGRATED ASSESSMENT OF THE HEALTH OF RIVER SOSIANI; KENYA
(University of Eldoret, 2013)This study set out to evaluate the effect of anthropogenic activities by analyzing the physical habitat characteristics, physico-chemical water quality parameters, macrophytes and macroinvertebrates as indicators of ... -
LEVELS AND DISTRIBUTION OF POLYCHLORINATED BIPHENYLS (PCBS) IN WATER, SEDIMENT, FISH AND THEIR ASSOCIATED PARASITES IN LAKE VICTORIA - KENYA
(University of Eldoret, 2015)To fulfill regulatory requirements on flame retardancy, flame retardants like Polychlorinated Biphenyl (PCBs) are incorporated into a number of polymers. These chemicals are toxic, persistent, and bioaccumulate in biota. ... -
MODELLING LAKE LEVEL VARIATIONS, WATER BALANCE, AND FISHERIES OF LAKE BARINGO, KENYA
(University of Eldoret, 2022)Lake Baringo has the worst eroded catchment area and whose water levels (WLs) have been fluctuating at inter- and intra-annual time scales. These changes have been related to natural events and to human activities in the ... -
NESTING ECOLOGY OF THE GREEN TURTLE (LINNAEUS, 1758) IN COASTAL KENYA.
(2016-05-20)During the past several decades there has been a general global decline in sea turtle populations attributed either directly or indirectly to anthropogenic and climate change effects. Relatively little is known regarding ... -
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 ... -
