The role of indigenous knowledge in fisheries resource management for aquaculture development: A case study of the Kenyan Lake Victoria region
(Wiley, 2023)Indigenous knowledge is critical in the conservation of wild fish genetic resources and consequent development of fish seed for improved aquaculture production. Local fisher communities rely on aquatic resources mainly ... -
The use of phosphate rocks in East Africa: A review
(Indian journals, 2023-04-06)The use of locally available phosphate rock (PR) has often been proposed as a cheaper alternative to the more expensive superphosphate fertilizers to alleviate severe phosphorus deficiencies that threaten food security in ... -
Determinants of fish farmers’ awareness of insect-based aquafeeds in Kenya; the case of black soldier fly larvae meal
(Cogent, 2023-03-09)It is evident from scientific studies that black soldier fly larvae can replace the widely used fishmeal, which is costly and unsustainable for smallholder farmers, in aquafeeds. The purpose of this study was to evaluate ... -

Impacts of Covid-19 Pandemic and Adaptive Strategies to Build Resilience in the Kenyan Aquaculture Sector
(ScienceOpen, 2022)This study examines the impacts of the Covid-19 pandemic and adaptive strategies to build resilience among stakeholders and actors in the aquaculture value chain in Kenya. Prior to the pandemic, Kenya's aquaculture sector ... -
Socio-economic consequences of imported frozen tilapia in the Kenyan aquaculture value chain: Strategies for optimizing local unexploited potential
(ScienceOpen, 2022)The capture fisheries production sector, which is the main source of consumed fish in Kenya has been declining over the years, causing a huge deficit in fish supply in the local market. Even though aquaculture has been ... -
Fish and fish products consumption behaviours and attitudes of farmers in western Kenya.
(ResearchGate, 2022)Fish and fish products contain high-quality protein of animal origin with essential bioavailable micronutrients such as iron, zinc, vitamins and omega-3 fatty acids. Although fish contribute to food and nutrition security, ... -
Lake Turkana: Status, challenges, and opportunities for collaborative research
(Elsevier, 2022)Lake Turkana, located in northwestern Kenya and south-western Ethiopia, is Africa’s fourth largest lake and the world’s largest permanent desert lake. The lake lies in a closed basin and its limnology, ecology, and fisheries ... -
Growth Performance of African Catfish (Clarias Gariepinus) Fed on Diets Containing Black Soldier Fly (Hermetia Illucens) Larvae Under Aquaponic System
(AQUAST910, 2022)Cost of fish production can be reduced by replacement of high-priced fishmeal (FM) with insects sourced ingredients. Four months feed experiment was conducted at a fish farm in Baringo County, Kenya to investigate effects ... -
Factors Affecting Productivity and Profitability of Cage-Fish Farming in Siaya County, Kenya
(KALRO, 2022)Aquaculture is regarded as a critical rural development and livelihood strategy due to its vital role in livelihoods and the economy at large. However, declining capture fisheries from Lake Victoria and low pond productivity ... -
Biofloc and green water condition improves reproductive traits and fatty acid composition of Artemia franciscana cultured under limited algal conditions
(John Wiley & Sons, Ltd, 2022-11-29)This study investigated the effect of biofloc and green water conditions on the survival, growth, reproductive traits, and fatty acid composition of the brine shrimp Artemia franciscana. Artemia was cultured in glass jars ... -
Genetic and non-genetic factors influencing KLH binding natural antibodies and specific antibody response to Newcastle disease in Kenyan chicken populations

Farm diversification benefits and technology choice: A case of the coffee-banana farming system in Central Uganda
(African Journal of Agricultural Research, 2023)Diversification has been argued to be the future of small farms and more so in developing countries given its benefits to mitigating against risk, increase economic and social benefits. This study was built on an earlier ... -
Sorghum is an important staple food crop in Kenya, but its yield is low due to many constraints which include diseases, drought, soil fertility, and pests, notably parasitic weed Striga hermonthica. Twenty elite sorghum genotypes and one resistant check were evaluated in three replications in a complete randomized design in Agar Gel (AG) experiment and randomized complete block design on selected Striga hotspot farms at Kadel and Nyahera in western Kenya. Significant differences (p<0.001) were realized both in the fields (plant height, dry shoot biomass yield, grain yield, field Striga count, and Striga damage ratings) and in the AG experiment with respect to maximum germination distance and numbers of induced germinated Striga seeds. Among the sorghum genotypes evaluated under field conditions, T53B, N57, N68, C26, IESV 92036-SH, T30B, and Uyoma 47 White genotypes had stable yields under Striga infestation in the two sites, whereas Nyadundo 1, Nyadundo 2, and Uyoma 8 were susceptible. In the AG experiment, E117B, T30B, Uyoma 8, Uyoma 42 STR, and T53B induced high numbers of germinated Striga seeds with maximum germination distances (MGD). In contrast, Uyoma 47 Brown, IESV 92038/2-SH, and IESV 92036-SH sorghum genotypes secreted low amounts of SLS suggesting resistance. This study has identified and selected four Striga tolerant (T53B, N68, N57, and T 30B) and resistant (C 26, Uyoma 47 Brown, IESV 92038/2-SH, and IESV 92036- SH) sorghum genotypes which can be utilized in further research programs or adopted to improve sorghum productivity in the highly Striga infested regions of western Kenya.
