DYNAMICS IN TROPHIC STATUS, WATER AND NUTRIENT MASS BALANCE AND COMMUNITIES OF LAKE KANYABOLI, KENYA
(University of Eldoret, 2022-10)Fishing pressure and nutrient enrichment from the catchment area threaten Lake Kanyaboli's water quality and communities. Understanding these impacts and their effect on the lake's water quality and communities is crucial ... -
ECOLOGICAL CARRYING CAPACITY AND GROWTH PERFORMANCE OF NILE TILAPIA (Oreochromis niloticus) IN CAGE AQUACULTURE WITHIN KADIMO BAY, LAKE VICTORIA, KENYA
(University of Eldoret, 2024-01)Fish production in the wild is decreasing globally due to a number of factors including overfishing, pollution, invasive species, and climate change effects. In Kenya, fisheries contribute less than 1% to the national GDP ... -
ECOSYSTEM-BASED ASSESSMENT OF THE MALINDI-UNGWANA BAY PRAWN FISHERY USING ECOLOGICAL INDICATORS
(University of Eldoret, 2014)The study aimed to generate information that will contribute to development of an Ecosystem based approach to fisheries management (EAFM) of prawn resources in the Malindi-Ungwana Bay, Kenya. A comprehensive ecosystem-based ... -
THE EFFECT OF AMINO ACID SUPPLEMENTED DIETS ON GROWTH PERFOMANCE OF NILE TILAPIA (Oreochromis niloticus Linnaeus, 1758) FINGERLINGS REARED IN HAPAS SUSPENDED IN EARTHEN POND
(University of Eldoret, 2018)Commercial diets are produced in bulk with significant anti-nutritional factors increasing aquaculture production cost. The proximate composition of local feed ingredient is limited by unbalanced dietary amino acid ... -
THE EFFECT OF AMINO ACID SUPPLEMENTED DIETS ON GROWTH PERFOMANCE OF NILE TILAPIA (Oreochromis niloticus Linnaeus, 1758) FINGERLINGS REARED IN HAPAS SUSPENDED IN EARTHEN POND
(2018)Commercial diets are produced in bulk with significant anti-nutritional factors increasing aquaculture production cost. The proximate composition of local feed ingredient is limited by unbalanced dietary amino acid contents, ... -
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 ... -
EFFECT OF IRON AMINO ACID CHELATE SUPPLEMENT IN FISH FEEDS ON GROWTH PERFOMANCE OF NILE TILAPIA (Oreochromis niloticus Linnaeus, 1758) AND SPINACH (Spinacia oleracea Linnaeus, 1552) IN AN AQUAPONIC SYSTEM
(University of Eldoret, 2018)Aquaponic is the combination of aquaculture and hydroponics. It is an environmentally friendly production system involving reuse of waste and nutrients in production of fish and vegetables. The research was conducted to ... -
