(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 ... -
GENETIC DIVERSITY, POPULATION STRUCTURE AND INFLUENCE ON LIFE-HISTORY TRAITS OF THE AFRICAN CATFISH, CLARIAS GARIEPINUS (BURCHELL 1822), IN KENYA
(University of Eldoret, 2018)The African catfish, Clarias gariepinus (Burchell 1822) is an important species in fisheries and aquaculture in Africa. In Kenya, farmers use seeds of unknown genetic characteristics. Sourcing of brood stock for propagation ... -
SPATIAL – TEMPORAL DISTRIBUTION AND ABUNDANCE OF LARVAL STAGES OF NILE PERCH (Lates niloticus LINNAEUS 1758) IN LAKE VICTORIA, KENYA
(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 ... -
