ABILA Research Officer Kenya Marine and Fisheries Research Institute P.O. Box 1881 Kisumu, Kenya Introduction Trawling is a unique technique of harvesting fish on Lake Victoria. It is a modern method requiring relatively high capital investment and is capable of using complex scientific gadgets in monitoring and hauling fish. The fish caught by an average trawler may be many times what a local fishing unit may produce. Therefore, a trawler will yield higher catch per unit of labour and time input in a fishing operation than the traditional fishing boats. There is an official ban in place on commercial trawling in all three East African countries. Despite this, illegal trawling has persisted, presumably with the tacit knowledge of the government officers responsible for enforcing the ban. It appears that the incentives and profits attained in trawling are so high that some trawler owners continue in the business even at the risk of being prosecuted. Alternatively it may be that trawler owners are very powerful and influential people in business or in the civil service. Evidence shows that among the initial owners of trawl boats in Kenya were top government officials, including a Cabinet Minister and an Assistant Director of Fisheries living in the lake region. The profit motives and the powerful forces in the trawler industry effectively ensured that "disused" and non-performing vessels previously owned by the government of Kenya for the delivery of social services, in patrolling the lake and transporting passengers and goods, were purchased by private businessmen and renovated into trawlers. In this way, vessels owned by the Fisheries Department, Kenya Police, Ministry of Health, Customs Department and Kenya Railways were not repaired to continue in Government services, but sold off to rich and powerful individuals to be converted into trawlers. 26 Trawling, being a non-selective fishing method, management plan, Lake Victoria may not be the can destroy the biodiversity and ecology of the ideal environment for commercial trawling. lake.

Direct Correspondence to, Ecopolicy Center, Continuing Education Annex, PO Box 270, Rutgers University, New Brunswick NJ 08903 908-932-9583x15, fax 932-9544, [email protected] The author would like to acknowledge the support of: the Social Science Research Council's International Predissertation Fellowship Program; the Michigan State University African Studies Center; and the Tanzanian Fisheries Research Institute. Without the support and encouragement of these institutions this research would not have been possible. INTRODUCTION Lake Victoria is located in East Africa, on the equator, and is shared by Kenya, Uganda, and Tanzania. There are a number of current environmental problems associated with Lake Victoria and its basin. There has been a critical loss of biodiversity in the lake resulting from the introduction of exotic species. Pollution is a serious problem near the larger towns. Use of firewood in the processing of fish has made a significant contribution to the already sobering rates of deforestation in the lake basin and surrounding areas. The lake is suffering from a recent invasion of water hyacinth; an attractive, rapidly spreading, pernicious weed which blocks easy access to the lake while depleting oxygen needed by other species. While all of these problems are in need of sociological analysis this paper concentrates only on the problem of the over-fishing of the stocks of commercial fish species. The Lake Victoria fisheries are among the world's most important inland fisheries. Between 1975 and 1989 the lake fisheries produced a total value on the order of 280 million U.S.

Box 343 Jinja, Uganda E-mail [email protected] Introduction Rastrineobola argentea locally known as mukene in Uganda, omena in Kenya and dagaa in Tanzania occurs in Lake Nabugabo, Lake Victoria, the Upper Victoria Nile and Lake Kyoga (Greenwood, 1966). While its fishery is well established on Lakes Victoria and 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. The introduction and subsequent establishment of the Nile perch Lates niloticus, and the Nile tilapia, Oreochromis niloticus, resulted into the disappearance of many native species from Lakes Victoria and Kyoga, through predation and competition for space (Ogutu Ohwayo, 1994, Witte et ai, 1992). R. argentea is presently the only indigenous fish species under commercial exploitation in these lakes.

Box 1625, Jinja, Uganda Email: [email protected] A paper prepared for Sharing of The Fish Conference 06, Espelanade Hotel, Fremantle, Perth, Western Australia. 23rd February – 2 March 2006 Abstract Africa has many large lakes most of which are shared between more than one country. One of them, Lake Victoria (68,000 km2) is shared between three East African Community (EAC) Partner States with 6% of the lake in Kenya, 43% in Uganda and 51% in Tanzania. The lake has a very lucrative fishery yielding 750,000m.t of fish valued at US$ 400 million annually. Fish exports from the lake earn Partner States US$ 250 million annually, and about 3 million out of 30 million people in the lake basin depend on the lake fisheries directly or indirectly for their livelihood. Management of the fisheries of Lake Victoria poses a challenge partly because management of the fisheries is by national governments under national jurisdictions. How then have the Partner States managed to harmoniously exploit the fisheries of the lake under multiple jurisdictions? The Partner States established a regional institution, the Lake Victoria Fisheries Organization (LVFO) to harmonize national measures, and to develop and adopt conservation and management measures for sustainable utilization of the fisheries. National measures are harmonized into regional measures and agreed upon through the structures from the national village level to a Ministerial regional level. The LVFO then developed programs and formed Working Groups (WGs) at national and regional levels through which different activities are implemented.

  • A Study of Fishing Pressure on Nile Perch Fishery on Lake Victoria
    A study of impacts of fishing pressure on Nile perch fishery on Lake Victoria (Uganda) using fisher folk community collected data G. Katurole and J. Wadanya Fisheries Resources Department, P.O. Box 4, Entebbe, Uganda Abstract Fishery management on Lake Victoria in Uganda is constrained by lack of an effective fishery monitoring and regulatory mechanism, coupled with inadequate budgetary allocations to the fisheries sub-sector. This has led to high fishing pressure and a decline in the fishery. This paper presents a preliminary analysis of fisher-folk data collected over a period of one year at four landing sites in four districts along Lake Victoria in Uganda under a co-management pilot project aimed at addressing some of the problems in the fishing industry. Gear type and size and catch size of Nile perch in the different gear types/sizes was examined. Results indicated a declining fishery. Around 62.7% of the fishing canoes that target Nile perch on the lake were using fishing gears and methods that catch high proportions of immature Nile perch. Around 7.1% of the canoes caught Nile perch that was predominantly immature and illegal. Some 43.4% of the Nile perch in the overall sample was smaller than the size at first maturity for males and around 99.7% was below the size at first maturity for females. Expansion of the project in space and time, together with a revision of the current fishery regulatory law is recommended to improve the fishery management on Lake Victoria. Key words: Fishing pressure, Nile perch fishery, Lake Victoria-Uganda, co-management Introduction The fishing industry makes significant contribution to the welfare of Ugandans in terms of employment, food security, government revenue and foreign exchange earnings.
