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 ... -
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 ... -
Assessment of Duckweed Supplement Diet to Fishmeal on the Growth Performance of Oreochromis niloticus Fingerlings
(AER Journal, 2019)Oreochromis niloticus is the most cultured fish in tropical freshwater aquaculture systems and second most cultured fish after carps in the world. In Kenya, Oreochromis niloticus has potential in eradicating hunger and ... -
Biological aspects of Schilbe intermedius (Ruppell, 1832) in the Nyanza Gulf of Lake Victoria, Kenya
(Lakes & Reserv, 2019)Silver butter catfish (Schilbe intermedius) is an indigenous fish species in Lake Victoria. It has a good economic value because of the quality and freshness of its flesh, in creasing its demand for consumption. It is ... -
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 ... -
Some aspects of reproduction and feeding habits of Nile tilapia (Oreochromis niloticus) in three dams in Uasin Gishu County, Kenya
(Lakes & Reserv, 2019)Knowledge of the fisheries status of dams within Uasin Gishu County was needed prior to the government's plan to introduce fish and fisheries in the area. The dams were constructed in the 1950s and stocked with tilapia ... -
A review on the status of some major fish species in Lake Victoria and possible conservation strategies
(Lakes & Reservoirs, 2019)Lake Victoria, the second largest freshwater lake in the world, supports an enor mous flora and fauna biomass, with a large human population around the Lake. The lake is a source of food (fish), water for domestic use ... -
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 ... -
Distribution and composition of benthic macroinvertebrates functional feeding groups and ecosystem attributes under different land use patterns in Kipsinende River, Kenya
(International Journal of Fisheries and Aquatic Studies, 2020)Functional feeding groups in tropical rivers helps in understanding organic matter processing, energy flow, trophic relationship and management activities. This study aimed to describe the general distribution and ... -
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 ... -
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 ... -
Distribution patterns and diversity of riverine fishes of the Lake Victoria Basin, Kenya
(2020-08)The Lake Victoria Basin (LVB) is a global hotspot of aquatic biodiversity, but aquatic ecosystems are under threat from multiple stressors. Most studies on fish have focused on Lake Victoria, while patterns of fish diversity, ... -
Suitability of Soybean-Blood Meal Mixture as Replacement of Fish Meal in Nile Tilapia (Oreochromis niloticus) Rations
(African Environmental Review Journal (AER), 2020-12)Fish require high quality protein in their rations which is sourced from fish meal. However, its scarcity and competition for use in livestock feeds has caused escalation of prices thus limiting its use. A study was carried ... -
A review of the populations of tilapiine species in lakes Victoria and Naivasha, East Africa
(African Journal of Aquatic Science, 2021)This paper discusses the catch trends, population attributes and biological characteristics of tilapiine species that are both native and that have been introduced into Lake Victoria and Lake Naivasha. Predation by Lates ... -
