Effect of Stocking Density on Growth Performance, and Survival of Nile Tilapia (Oreochromis niloticus) in Cage Culture System in Lake Victoria, Kenya
(African Journal of Education, Science and Technology, 2023-04)The Nile tilapia (Oreochromis niltoticus) constitutes an important animal protein source in the Great African Lakes population but wild supplies are rapidly declining. Cage aquaculture of O. niloticus is increasingly being ... -
EFFECTS OF BIOFLOC TECHNOLOGY ON GROWTH PERFORMANCE OF NILE TILAPIA (Oreochromis Niloticus)FINGERLINGS AND MICROBIAL COLONIZATION IN THE SYSTEM.
(International Journal of Agriculture, Environment and Bioresearch, 2018)Aquaculture intensification is characterized by high stocking density and need of high quality and quantity of artificial feed. Increased fish biomass and feed input brings about rapid deterioration ... -
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 ... -
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 ... -
Generation of a Socio-Economic Suitability Map for Nile Tilapia (Oreochromis niloticus) Culture using Free Geographical Information System (GIS) software and Spatial Multi-Criteria Evaluation (SMCE) in Kisumu County, Kenya
(African Journal of Education, Science and Technology, 2022-06)In recent years, aquaculture has accounted for roughly half of all fish consumed globally. Scholar’s view aquaculture to have the potential to expand sustainably if suitable fish pond sites are located guided by ... -
