：Approximately 200 million people in Africa derive high-quality and low-cost proteins from fish. However, the consumption of fish is not fully exploited to combat “triple burden” malnutrition—obesity, undernutrition, micronutrient deficiencies which are leading causes poor health region. There still limited knowledge on quantitative information guide policy makers developing evidence-based actions that can improve availability access nutritious food for healthy sustained diets among children...

Land use, land cover, and climate change impacts are current global challenges that affecting many sectors, like agricultural production, socio-economic development, water quality, causing fragmentation. In developing countries Uganda, rural areas with high populations dependent on agriculture the most affected. The development of sustainable management measures requires proper identification drivers environment livelihoods affected communities. This study applied drivers, pressure, state,...

Background and Objectives Epitheliocystis, caused by bacteria infecting gill epithelial cells in fish, is common among a large range of fish species both fresh- seawater. The aquaculture industry considers epitheliocystis an important problem. It affects the welfare resulting disease may lead to mortalities. In culture facility Kampala, Uganda, juveniles African sharptooth catfish (Clarias gariepinus) was observed swimming surface, sometimes belly up, showing signs respiratory problems....

Despite their socio-economic and ecological importance, rivers are among the most threatened ecosystems. As a result, reliable affordable monitoring system is fundamental for effective management conservation. The utility of Biological Monitoring Working Party, BMWP (England, E) index developed temperate region BMWP-CR modified Costa Rica, tropics, were compared assessing water quality River Aturukuku in Eastern Uganda. Benthic macroinvertebrates used biomonitoring study because wide...

Stream metabolism is a fundamental ecosystem function that includes gross primary productivity (GPP) and respiration (ER). These processes measure the energy supply consumption in aquatic system are basis for green brown food webs. Because of their sensitivity to environmental stressors, they important management as functional indicators ecosystem’s health. They also have benefit being an integrative indicator change since influenced by multiple factors at different scales....

Climate change (CC) is now a global challenge due to uncertainties on the drivers and multifaceted nature of its impacts. It impacts many sectors such as agriculture, water supply, economies through temperature precipitation, affecting livelihoods. Although there are global, regional, national studies CC, their application determine local CC occurence mitigation adaptation measures not ideal. Therefore, this study aimed climate trends in Lake Kyoga Basin using standardized precipitation...

Abstract Studies to examine the prevalence of water‐related diseases, cyanobacteria toxins and other health risks at landing beaches in Ugandan portion Lake Victoria basin were carried out. Based on surveillance studies data sources region, water samples analysed for indications faecal contamination. The coliform numbers generally high most sampling sites, indicating significant wet seasons exhibited significantly higher counts than dry all lakeshore sample sites. This seasonal variation...

We investigated morphological characteristics and treatment potential of Cyperus papyrus, Typha domingensis, Miscanthidium violaceum, Phragmites mauritianus receiving slaughterhouse wastewater in Kampala, Uganda, experimental mesocosms. Unplanted mesocosms acted as controls. All planted achieved significantly higher removals for nitrogen, phosphorus organic matter than unplanted Among macrophytes, C. papyrus depicted highest pollutant uptake. The umbel had the concentration (3.9 mg/g dry...

Catchments for aquatic ecosystems connect to the water quality of those waterbodies. Land use land cover change activities in catchments, therefore, play a significant role determining Research on relationship between and changes has gained global prominence. Therefore, this study aimed at use, catchments L. Kyoga basin, assessing their connectedness lake’s quality. The GIS software was used determine eight major 2000, 2010, 2020. Meanwhile, data obtained through both secondary primary...

Malaria is often persistent in communities surrounded by mosquito breeding habitats. Anopheles gambiae sensu lato exploit a variety of aquatic habitats, but the biotic determinants its preferences are poorly understood. This study aimed to identify and quantify macroinvertebrates different habitat types with determined water physico-chemical parameters establish those preferred An. s.l. larvae as well their predators competitors.A field survey was conducted Kibuye Kayonjo villages located...

A horizontal subsurface flow-constructed wetland (HSSF-CW) system planted with Cyperus papyrus was used to polish abattoir wastewater pre-treated in anaerobic and aerobic sequencing batch reactors at City Abattoir, Kampala. The HSSF-CW 13 m long, 5 wide, filled gravel up a depth of 0.6 m, which 0.55 saturated hydraulic retention time (HRT) 1.16 days. percentage removals for turbidity, ammonium-nitrogen (NH4-N), total nitrogen (TN), orthophosphate (o-PO4-P), phosphorus (TP), chemical oxygen...

Biodiversity conservation has focused on large vertebrates and plants with pronounced economic value, compared smaller organisms such as benthic macroinvertebrates that play a particular role in freshwater ecosystems. The increasing loss degradation of habitats, coupled low taxonomic ecological knowledge limited efforts the tropical regions, threaten macroinvertebrate biodiversity. This study investigated spatial seasonal variability diversity underlying environmental variables within...

Abstract This study examined the relationship between women's empowerment in agriculture (WEA), agency nutrition, and their food security. It aimed to quantify moderating effect of nutrition on association WEA Data from NutriFish project, a gender‐ nutrition‐sensitive agricultural intervention fishing villages Uganda, were utilized. The included 380 primary Ugandan female decision makers dual adult households. was measured using Project‐level Women's Empowerment Agriculture Index (pro‐WEAI)....

Low quality feeds are an impediment to sustainable fish farming in East Africa. affect growth, pollute the aquatic ecosystem, escalate conflicts among competing water resource users, and enterprise sustainability. We investigated physical nutrient attributes, aflatoxin levels of selected E. The actual crude protein lipid deviated from package quoted values by −20 7% −5.5 9.6%, respectively. All were inadequate essential minerals, their low (range: 8.71 ± 0.52 71.90 0.59 µg/kg). highlight...
