    Description: The survey covered by this report was undertaken between 6 th and 9th October 2009 as a follow-up on the during construction surveys of the Bujagali Hydropwer Project (BHPP). In addition to two pre-construction baseline surveys in April 2000 and April 2006, four monitoring surveys have so far been undertaken i.e. in September 2007, April 2008, April 2009 and the present one, in October 2009. The 2009 biannual monitoring surveys were conducted at an upstream and a downstream transect of the BHPP with emphasis on the following aspects: 1. water quality determinants 2. biology and ecology of fishes and food webs 3. fish stock and fish catch including economic aspects of catch and 4. sanitation/vector studies (bilharzias and river blindness)

    Description: Tullow Oil plc is to launch an onshore Early Production System (EPS) of oil drilling rated at 4,000 barrels of oil per day by 2009. The location of the EPS is in the Kaiso-Tonya area of Block 2 Oil Exploration Zone along Lake Albert within the Albertine graben. Tullow Oil plc contracted Environmental Resources Management (ERM) Southern Africa (Pty) Ltd in conjunction with Environmental Assessment Consult Limited (EACL) to undertake an Environmental Impact Assessment (EIA) for pre-construction and operation of the proposed EPS. ERM in association with EACL requested National Fisheries Resources Research Institute (NaFIRRI) to conduct a baseline survey of water quality and invertebrates in River Hohwa. This study was requested as part of an earlier baseline survey conducted at the Kaiso-Ngassa spit oil exploration area in Block 2. It was conducted at five selected sites (Fig. 1 & Table 1) within the Hohwa River basin in the Kaiso-Tonya Exploration Area 2. The study was pertinent because the targeted oil wells for EPS are upstream this river which drains the Kaiso-Ngassa valley into Ngassa lagoon.

    Description: postive transformation of the fisheries sector in Uganda has of recent been scatted by failure to mountain fish quality and safety,akey prerequiste for retaining and gaining fish markets.The social cultural study established the extent to which social cutural practices had affected the levels and the use of sanitation facilities,fish handling facilities and artisanal fish processing techniques and the factors that influenced these practices in the fishing communities of lake victoria.This information is of significance for the purpose of advocacy and mobilization of fishers in order to improve sanitation, fish handling and artisanal fishing processing situation in the fishing communities.

    Description: Following the commencement of construction works of a 250 MW hydropower plant at Dumbbell Island in the Upper Victoria Nile in September 2007, BEL requested NaFIRRI to conduct continuous monitoring of fish catches at two transects i.e. the immediate upstream transect of the project site (Kalange-Makwanzi) and the immediate downstream .transect (Buyala-Kikubamutwe). The routine monitoring surveys were designed to be conducted twice a week at each of the tWo transects. It was anticipated that major immediate impacts were to occur during construction, and these needed to be known by BEL as part of a mitigation strategy. For example, the construction of it cofferdam could be accompanied by rapid changes in water quality and quantity downstream of the construction. These changes in turn could affect the fish catch and would probably be missed by the quarterly monitoring already in place. Therefore, a major cbjective of the more regular and rapid monitoring was to discern immediate impacts of construction activities by focusing on selected water quality parameters (total suspended solids, water conductivity, temperature, dissolved oxygen and pH) and fish catch characteristics (total catch, catch rates and value of the catch)

    Description: The Nabugabo lakes are an important source of affordable protein food inthe form of fish, income, water for domestic and commercial purposes(aquaculture farm and Hotels), handcraft materials (mats, hats, roof thatch) andfishing floats and rafts. Nabugabo lakes provide employment, income and exportearnings to Uganda that flow from the act of harvesting the fish. In Uganda thefisheries sector directly employs 350,000 people and indirectly 1.2 million people.In 2005, it is estimated that about 370,000 mt fish export (97-98% Nile perch)earned Uganda US $ 143 Million up from US $ 103 million in 2004 .and up fromUS $ 45 million in 1996. , making it almost become the first non' traditional exportcommodity. The Nabugabo lakes are also import for cultural values and fishspecies from these lakes are important in evolutionary studies. The fishery sectoris therefore very important in Uganda's socio-economic life. Despite the abovevalues to the communities and global biodiversity roles, the amount of fish caughtand the number fishing fleets operating on the Nabugabo lakes to guidemanagement of the lake are lacking. The fishery that exists in these lakes islargely for subsistence and commercial purposes specific for Lake Nabugabobased on introduced species (Nile perch and Nile Tilapia). The fish is caughtusing mainly gill nets and long line hooks.

    Description: Rastrineobola argentea locally known as mukene in Uganda, omena in Kenya anddagaa in Tanzania occurs in Lake Nabugabo, Lake Victoria, the Upper Victoria Nile andLake Kyoga (Greenwood, 1966). While its fishery is well established on Lakes Victoriaand Kyoga, the species is not yet being exploited on Lake Nabugabo. Generally such smaller sized fish species as R argentea become important commercial species in lakes where they occur when catches of preferred larger-sized table fish start showing signs of decline mostly as a result of overexploitation. With the current trends of declining fish catches on Lake Nabugabo, human exploitation of mukene on this lake is therefore just a matter of time. The species is exploited both for direct· human consumption and as the protein ingredient in the manufacture of animal feeds.

Use of destructive fishing gears and methods e.g seines, cast nets, of recent mono-filament nets, tycooning, etc. 3. Capture of immature fish. 4. Invasion by water hyacinth and floating sudds 5. Ineffective management of fisheries due to limited (reluctance) community participation in lake management affairs. 6. Of recent, illegal buying and selling of fish in the lake without landing deprives the department of statistics and also puts the owner of fishing vessels at risk. 7. Lack of coordination among fisheries departments of districts of Kyoga basin (Le. differences in policies from districts to district -laxity in law enforcement). 8. Inadequate investment skills among fishers . .9. Political interference -creation of illegal landings 1a.llI-facilitated field staff. makes monitoring difficult and kills morale • . 11. Pollution and degradation of• the fish habitat from construction works and agro-cbemicals. 12. Poor infrastructure 13. Lack of control of licensing by fisheries staff 14.The rising water levels in the lake cause serious impacts to the fishing expeditions by way of destruction of the fishing gears and sudden blockages of landing site entries. 15. Some areas at the •shoreline show high degree of sedimentation. These areas being breeding areas for fish are seriously interfered. 16. Water hyacinth is still highly patched in some fishing grounds
