    Description: Kariba weed (Salvinia molesta) is an invasive alien waterweedthat was first recorded in Uganda in sheltered bays of LakeKyoga in June 2013. This waterweed has become a commonfeature on Lake Kyoga and its associated rivers, streams andswamps, and has spread to other lakes notably Kwania and Albert in addition to Lake Kimira in Bugiri district.

    Description: Fisheries activities are the main source of livelihood for the communities that live at Lake Edward fish landing sites. The landing sites include: Kazinga, Katwe, Kayanja, Kishenyi Rwenshama and Katunguru and are located within Queen Elizabeth Conservation Area (QECA).In spite of being the main source of livelihood, 74% of therespondents in a 2013 survey reported that catches forthe main targeted fish species namely: Bagrus docmak(Semutundu), Oreochromis niloticus (Tilapia) and Protopterusaethiopicus (Mamba) were declining due to overfishingand catching of immature fish by the rapidly increasingpopulation. Lake Edward Frame surveys had shown that thenumber of fishing crafts increased from 302 in 2008 to 330 in 2011, while the number of fishers increased from 355 to 600 during the same period. Between 2008 and 2010, catch perboat, for Bagrus docmak (Semutundu) declined from 5.25kg to 4.04 kg and for Protopterus aethiopicus (Mamba) from2.63 kg to 1.03kg.It has been suggested that reducing pressure on the lakeshould be handled using different approaches, one of whichis introduction of programs for enhancing livelihood optionswhich do not conflict with conservation of Queen ElizabethConservation Area (QECA). The main goal of this study wastherefore to identify, prioritize and pilot livelihood options at selected landing sites of Lakes Edward and George.

    Description: The National Fisheries Resources Research Institute (NaFIRRI), the Directorate of Fisheries Resources (DiFR), the Local Government fisheries staff and those from the Beach Management Units (BMUs) of the riparian districts to Lake Victoria regularly and jointly conduct Frame and Catch Assessment Surveys. The information obtained is used to guide fisheries management and development. We reveal the trends in the commercial fish catch landings and fishing effort on the Uganda side of Lake Victoria, over a 15 year period (2000-2015) and provide the underlying factors to the observed changes. The contribution of the high value large size species (Nile perch and Tilapia) to the commercial catch of Lake Victoria has significantly reduced while that of the low value small size species, Mukene has increased over a ten year (2005-2015)period. The information is intended to update and sensitize the key stakeholders on the status of the Lake Victoria fisheries. In addition, the information provided is expected to guide policy formulation and management planning by the fisheries managers at all levels including the BMUs and Landing Site Management Committees (LSMCs), the Local government fisheries staff and the Directorate of Fisheries Resources. The information is anticipated to create awareness among the lakeside fisher communities to reverse the current trend in fish declines.

    Description: As interest increases in fish production, fish farming is on the rise as more fish is produced in ponds, cages and tanks. However not all fish can be sold out and consumed at the same time, in addition to this, different consumers show different preference. Some individua Is tend to prefer smoked fish to fresh and fried fish. Apart from satisfying the different consumer preferences, fish smoking is important because it in creases the self life of fish, there by reducing post harvest losses. It also adds value to the fish and in this way the farmer can fetch more money from farmed products. Although the technology has been around for several years amongst the fishing communities, it is not well known amongst fish farmers. There is need to bring fish fanners on board to know how to construct the smoking kiln through the stapes out lined below.

    Description: Sobre la base de los objetivos propuestos, el muestreo tiene que estar cuidadosamente planeado (diseño de protocolo de muestreo) para que se pueda realizar una comprobación estadística de los resultados. Las herramientas de análisis como son los cálculos numéricos y los análisis estadísticos están ligados al estudio en sí, ya que son los que nos permiten demostrar que los resultados de una investigación son el producto de procesos ecológicos y no del azar.

    Description: Algae are microscopic plants in aquatic environments, and inc}ude blue-green algae (Cyanobacteria), green algae (Chlorophytes) diatoms (Bacillariohytes), Cryptophytes and Chrysophytes. Several of these groups co-exist but some may be absent due to environmental limitations existing in a specific water body. Algae are important in the aquatic food chains because algal primary production provi~es the basis for which the aquatic food linkages culminating in the fish production. Several groups of algae in communal or symbiotic association with bacteria mediate many biogeochemical processes, which characterise aquatic habitats, such as nitrogen, carbon, iron, sulphur recycling and consumption of oxygen. However, excess algal production in aquatic ecosystems can lead to deleterious effects, including deterioration in the water quality due to production of phycotoxins, reduced photosynthetic rates due to self-shadding and high BOD due to algal biomass collapse. The health of Lake Victoria is directly related to human impacts on the fisheries, wetland buffers and water quality
