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 ... -
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 ... -
Some biological aspects of the Silurid Catfish, Bagrus docmak (Forksskal, 1775) in Lake Victoria, Kenya
(Journal of Fisheries & Aquaculture, 2021-02)Bagrus docmak is indigenous to Lake Victoria, being an important source of economic livelihoods to communities around the lake. Although its stocks in the lake are facing intense fishing, predation and ecological changes, ... -
KEY LIMITATIONS OF FISH FEEDS, FEED MANAGEMENT PRACTICES, AND OPPORTUNITIES IN KENYA’S AQUACULTURE ENTERPRISE
(African journal of Food, Agriculture, Nutrition and Development (ajfand), 2021-03)Profitability is key in fish farming, just as it is to any other enterprise. For the farmers to actualize high-profit margins, it is imperative to have access to well-balanced nutritive and cost-effective feeds, backed ... -
Land-use influence on the functional organization of Afrotropical macroinvertebrate assemblages
(ELSEVIER, 2021-04)Studies investigating the effects of human activities on the functional organization of macroinvertebrate communities in tropical streams and rivers are very limited, despite these areas witnessing the greatest loss of ... -
Effects of Deployment Period on Decomposition and Colonization of Leaf Litter of Differing Quality by Invertebrates
(African Journal of Education, Science and Technology (AJEST), 2021-05)Detritivorous invertebrates play major roles in organic matter processing and nutrient cycling in headwater streams. In this study, three common leaf species in upland Kenyan streams (Vernonia myriantha, Syzygium cordatum ... -
Seasonality in environmental conditions drive variation in plankton communities in a shallow tropical lake
(Frontiers in water, 2022)Factors influencing the spatio-temporal dynamics of plankton communities in small tropical lakes are not well-understood. This study assessed plankton communities in response to spatial (six sampling sites) and seasonal ... -
Drivers of water quality in Afromontane-savanna rivers
(Frontiers in Environmental Science, 2022)Although several studies have investigated the relationships between water quality in rivers and the types of land use within their catchments, many aspects of these relationships remain unclear in Afromontane-savanna ... -
