EFFECTS OF SUBSTITUTING FISH MEAL WITH SOYBEAN-BLOOD MEAL MIXTURE ON PERFORMANCE OF NILE TILAPIA (Oreochromis niloticus)
(University of Eldoret, 2018) -
EFFECT OF ELEVATED TEMPERATURE TREATMENT AND PAWPAW SEED POWDER ON PRODUCTION OF STERILE MONOSEX NILE TILAPIA
(University of Eldoret, 2019)Nile tilapia is the most widely cultured fish species in Kenya. The greatest problem with tilapia is its prolific breeding due to mixed sex, resulting in stunted growth of the fish. Therefore, there was a need to employ ... -
A COMPARATIVE STUDY OF GROWTH RATES AND YIELD OF THE SEAWEED, Kappaphycus alvarezii (Doty), USING VARIABLE SEEDLING DENSITIES AND CULTURE METHODS IN COASTAL KENYA.
(University of Eldoret, 2019)Seaweed farming has been demonstrated to have significant socio-economic benefits to coastal communities and has the potential to reduce pressure on wild fishery stocks. This work was aimed at testing sustainable farming ... -
EFFECTS OF STOCKING DENSITY ON GROWTH, WATER QUALITY AND ECONOMIC PERFORMANCE OF MONOSEX NILE TILAPIA (Oreochromis niloticus) REARED IN AQUAPONICS SYSTEM
(University of Eldoret, 2021)Aquaponic systems integrate the culture of both plants and fish in recirculating aquaculture units. The nutrients derived from the fish are utilized by the plants for their growth in the system. The current study determined ... -
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 ... -
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 ... -
EFFECTS OF STOCKING DENSITY AND SEASONALITY ON DIGENEAN TREMATODE AND MONOGENEAN INFECTIONS IN NILE TILAPIA (Oreochromis niloticus, Linnaeus 1758) REARED IN CAGES IN UHANYA BEACH IN LAKE VICTORIA, KENYA
(University of Eldoret, 2021)There exists a balance between, parasites, their fish hosts and the environment. However, when this balance is broken parasites spread rapidly in culture facilities inducing severe epizootics. This study was conducted from ... -
FOOD, FEEDING HABITS AND POPULATION STRUCTURE OF “NINGU” (Labeo victorianus, BOULENGER, 1901) IN FOUR SELECTED RIVERS OF THE LAKE VICTORIA BASIN, KENYA.
(University of Eldoret, 2021)“Ningu” (Labeo victorianus Boulenger, 1901) is one of the endemic fishes in Lake Victoria Basin (LVB), but is now threatened by multiple stressors caused by human activities. This study investigated spatial and temporal ... -
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 ... -
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 ... -
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 ... -
