ABSTRACT The Winam Gulf in the Kenyan region of Lake Victoria experiences prolific, year-round cyanobacterial harmful algal blooms (cyanoHABs) which pose threats to human, livestock, and ecosystem health. To our knowledge, there is limited molecular research on gulf’s cyanoHABs, thus, strategies employed for survival proliferation by toxigenic cyanobacteria this remain largely unexplored. Here, we used metagenomics analyze Gulf’s composition, function, biosynthetic potential. Dolichospermum...
The Nile perch (Lates niloticus L.) commercial fishery for Lake Victoria in East Africa is an important source of revenue and employment. We focused on shifts food web structure total mercury (THg) bioaccumulation biomagnification perch, lower items collected from Winam Gulf (Kenya) sampled 24 years apart (1998 2022). Stable isotope carbon (δ13C) values were higher all species 2022 compared to 1998. nitrogen (δ15N) baseline organisms In δ15N correlated with length, but the δ15N-length...
The sea louse, Lepeophtheirus salmonis, is parasitic to salmonid species in the Northern Hemisphere and has become a widespread biological economic problem for salmon farming industry. A better understanding needed of their spatial distribution early life history disrupt cycle louse. In this study, lice larval densities within farms, between farms reference sites, at various depths were quantified using both plankton pumps nets. Farm sites exhibited significantly higher than sites; however,...
We report 40 metagenomic libraries collected from the Winam Gulf of Lake Victoria during May-July 2022-2023 and an additional eight opportunistic adjacent Lakes Simbi, Naivasha, regional river systems. The sampling period captured cyanobacterial bloom events - shedding insight onto community composition genomic potential.
East African lakes support the food and water security of millions people. Yet, a lack continuous long-term quality data for these waterbodies impedes their sustainable management. While satellite-based retrieval methods have been developed globally, are typically underrepresented in training data, limiting applicability existing to region. Hence, this study aimed (1) assess accuracy newly band algorithms (2) make satellite-derived information easily accessible through Google Earth Engine...
