(Journal of Advance Research in Food, Agriculture and environmental science, 2018)Toxicants cause a wide range of concerns in the health of fish. The specific objectives of the study were determine aberration of growth and survival as an iron indicator on exposure to lambda cyhalothrin and aflatoxins ... -
High genetic diversity and population differentiation in Clarias gariepinus of Yala Swamp: evidence from mitochondrial DNA sequences
(Journal of Fish Biology (2016) 89, 2557–2570, 2016-07)In order to improve the conservation and sustainable utilization of the African catfish Clarias gariepinus of the Yala Swamp in Kenya, genetic diversity and population structure of Lakes Kanyaboli and Namboyo populations ... -
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 ... -
Influence of catchment land use and seasonality on dissolved organic matter composition and ecosystem metabolism in headwater streams of a Kenyan river
(Biogeochemistry An International Journal, 2017-01)Headwater streams influence the biogeochemical characteristics of large rivers and play important roles in regional and global carbon budgets. The combined effects of seasonality and land use change on the biogeochemistry ... -

(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 ... -
Influence of Water Quality on Distribution Patterns and Diversity of Enteromius Fish Species in Small Water Bodies of Uasin Gishu County, Kenya
(African Journal of Education, Science and Technology, 2022)The Enteromius species are a widely distributed group of freshwater fishes in Africa. However, their abundance and diversity are affected by environmental quality. This study therefore investigated the relationship between ... -
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 ... -
Litter processing and shredder distribution as indicators of riparian and catchment influences on ecological health of tropical streams
(Ecological Indicators, 2014-05)Terrestrial plant litter is the main source of energy for food webs in forest headwater streams. Leaf litter quality often changes when native tree species are replaced by exotic ones and land use change in the watershed ... -
