Recent changes in fish communities of the equatorial Lake Naivasha, Kenya
(International Journal of Fisheries and Aquaculture, 2013-04)Changes in fish species composition and abundance in Lake Naivasha were investigated monthly for a period of 12 months. Data were obtained both from experimental surveys as well as commercial fish landings. The structure ... -
Growth, Survival and Nutrient Utilization of Nile Tilapia (Oreochromis niloticus) using Cyanophyceae (Arthrospira fusiformis) as Replacement of Fishmeal Based Diets
(International Journal of Science and Research (IJSR), 2014-08)Suitability of using cynaophyceae (Arthrospira fusiformis) to replace fishmeal (Caridina nilotica) as a main protein source in the diet of Nile tilapia (Oreochromis niloticus) was investigated at a ratios of: 25%, 50%, 75% ... -
Dynamic of Stress Response in Victoria Labeo (Labeo victorianus) during transfer from the Hatchery to cages and Ponds under Differential Caged Stocking Densities
(International Journal of Science and Research (IJSR), 2012)Variation in fish stocking densities translate to difference in growth performance, yields and economic benefits in fish culture. Transferring fish directly from hatcheries to the cages or ponds may induce stress. We ... -
Haematological Response of Rastrineobola argentea Exposed To Subchronic Doses of Inorganic Cadmium (Cd), Methylmercury and Polychlorinated Biphenyl (PCB) via Dietary Exposure Pathway
(International Journal of Science and Research (IJSR), 2012)Haematological indices provide information on various aspects of fish health when exposed to environmental contaminants. We evaluated the effects of cadmium, methyl mercury (MeHg), and Polychlorinated Biphenyl (PCB) on the ... -
Remote Sensing Applications for Sustainable Aquaculture in Africa
(IEEE, 2007)The authors review the current state of the science with respect to remote sensing applications for aquaculture, including site location, aquaculture facility mapping, market proximity analysis and associated roadway ... -
Influences of land use/cover on water quality in the upper and middle reaches of River Njoro, Kenya
(Lakes & Reservoirs: Research and management, 2007-06)Data from 10 sampling sites along the River Njoro are used to examine the contribution of nutrients from upstream land uses draining each of the sampling sites. The data also are used to assess whether both the proportion ... -
Ecology and Management of Lake Naivasha, Kenya, in Relation to Climatic Change, Alien Species' Introductions, and Agricultural Development
(Environmental Conservation; Cambridge Journals, 1990)Lake Naivasha is an important freshwater resource for Kenya's foreign-currency-earning agriculture and tourism, and for water-supply. It has always experienced extensive water-level fluctuations as a consequence of irregular ... -
The introduced species fishery of Lake Naivasha, Kenya: ecological impact vs socio‐economic benefits
(FISHERIES MANAGEMENT AND ECOLOGY, 2015-08)Lake Naivasha is a shallow, freshwater lake in the eastern Rift Valley of Kenya. Its fish community now comprises only introduced species. Oreochromis spirulus niger was stocked in 1925 as a forage fish for the largemouth ... -
Zooplankton partitioning in a tropical alkaline-saline endorheic Lake Nakuru, Kenya: Spatial and temporal trends in relation to the environment
(Lakes & Reservoirs: Research and management, 2011)Spatial and temporal zooplankton variations were studied for 1 year in tropical alkaline–saline Lake Nakuru to determine how they partition in the habitat, relative to environmental variables. Monthly samples were collected ... -

The status and future of the Lake Naivasha fishery, Kenya
(Kluwer Academic Publishers, 2002)Lake Naivasha is a freshwater lake situated in the eastern rift valley of Kenya. Only five species of fish are present, all of which have been introduced. They are Oreochromis leucostictus, Tilapia zillii, Micropterus ... -
Difficulties of fishing at Lake Naivasha, Kenya: is community participation in management the solution?
(2010)Unlike other lakes in tropical regions, Lake Naivasha exhibits low fish species diversity. The fishery is based on introduced fish species that are not native to the lake. The lake ecosystem is very fragile, as reflected ... -
Economic Gain versus Ecological Damage from the Introduction of Non-native Freshwater Fish: Case Studies from Kenya
(2008)Non-native freshwater fish species that have been introduced to the inland waters of Kenya are listed and the consequences of stocking such fish are reviewed. Original species composition and lake ecosystem function can ... -
Habitat degradation and subsequent fishery collapse in Lakes Naivasha and Baringo, Kenya
(2004)Lakes Naivasha and Baringo in the eastern Rift Valley of Kenya are shallow, freshwater lakes that are subject to major fluctuations in water level and suffer from habitat degradation as a consequence of riparian activity. ...
