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 ... -
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 ... -
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 ... -
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 ... -
Dynamics in Organic Matter Processing, Ecosystem Metabolism and Trophic Sources for Consumers in the Mara River, Kenya
(CRC Press/Balkema PO Box 11320, 2301 EH Leiden, The Netherlands e-mail: Pub.NL@taylorandfrancis.com www.crcpress.com – www.taylorandfrancis.com, 2015-03) -
Are Large Herbivores Vectors of Terrestrial Subsidies for Riverine Food Webs?
(Springer Science+Business Media New York, 2015-03-17)The tropical savannas of Africa have witnessed a dramatic reduction in native large mammalian herbivore populations. The consequences of these changes for terrestrial-aquatic food-web linkages are poorly documented. ... -
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 ... -
Macroinvertebrate functional feeding groups in Kenyan highland streams: evidence for a diverse shredder guild
(The Society for Freshwater Science, 2014-02)Data on the functional composition of invertebrates in tropical streams are needed to develop models of ecosystem functioning and to assess anthropogenic effects on ecological condition. We collected macroinvertebrates ... -
Genetic identification of invasive walking catfish, Clarias batrachus, intermingled with African catfish, C. gariepinus, in South Africa
(African Journal of Wildlife Research 45(1): 55–62 (April 2015), 2015-04)Molecular genetic techniques were used to determine the identity of two catfish individuals that could not be identified as indigenous Clarias gariepinus after phenotypic analysis. The unidentified catfish were compared ... -
Genetic diversity and population structure of the African catfish, Clarias gariepinus (Burchell, 1822) in Kenya: implication for conservation and aquaculture
(Belgian Journal of Zoology, 2017)African catfish, Clarias gariepinus, is an important species in aquaculture and fisheries in Kenya. Mitochondrial D-loop control region was used to determine genetic variation and population structure in samples of C. ... -
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 ... -
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, ... -
ENDOHELMINTHS OF Oreochromis niloticus baringoensis (Trewavas, 1983) AT RIVER MOLO INLET IN LAKE BARINGO, KENYA
(2018)Endohelminths infections in fish cause production and economic losses through direct fish mortality, reduction in growth and condition, reproduction, energy loss, increase in the susceptibility to disease and predation. A ... -
THE EFFECT OF AMINO ACID SUPPLEMENTED DIETS ON GROWTH PERFOMANCE OF NILE TILAPIA (Oreochromis niloticus Linnaeus, 1758) FINGERLINGS REARED IN HAPAS SUSPENDED IN EARTHEN POND
(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 contents, ... -
SPATIAL – TEMPORAL DISTRIBUTION AND ABUNDANCE OF LARVAL STAGES OF NILE PERCH (Lates niloticus LINNAEUS 1758) IN LAKE VICTORIA, KENYA
(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 ... -
Use of macroinvertebrate assemblages for assessing performance of stabilization ponds treating effluents from sugarcane and molasses processing
(Springer, 2017)Wastewater discharge from sugarcane processing is a significant pollutant of tropical aquatic ecosystems. For most developing countries, monitoring of the level of pollutants is done mostly through chemical analysis, but ... -
A STUDY ON GROWTH PERFORMANCE AND VIABILITY OF THREE MARINE FISH SPECIES UNDER CAGE CULTURE IN THE KENYAN COAST
(2016-05-23)This study set out to investigate and compare the growth performance and viabilities of three different marine fish species for commercial cage culture. The study was carried out in Makongeni village along Kenya coast ... -
NESTING ECOLOGY OF THE GREEN TURTLE (LINNAEUS, 1758) IN COASTAL KENYA.
(2016-05-20)During the past several decades there has been a general global decline in sea turtle populations attributed either directly or indirectly to anthropogenic and climate change effects. Relatively little is known regarding ... -
