Report on the current state of the fishery of the Ugandan sector of Lake Albert

Following a general outcry by the population riparian to the Ugandan portion of lake Albert about dwindling fish catches, there was concern both from the FAO Country representative in Uganda and the government of Uganda on the state of the fisheries of this lake. The FAO representative accompanied by an official from the Uganda Fisheries and Fish Conservation Association (UFFCA) visited the lake in July 1999 (Appendix I). The Ugandan minister of state in charge of the Fisheries sector also visited the lake in November 1999 (Appendix II). The two were in common agreement that the lake was in a stocks crisis and there was need for remedial measures. It was therefore deemed necessary to initiate a technical report updating the present state of the fisheries resources of this lake. An agreement was thus signed between the author and the Food and Agricultural Organization of the United Nations - Sub-Regional Office for Southern Africa in Harare, to undertake this exercise.

Current composition, distribution and relative abundance of the fish stocks of Lake Victoria, Uganda

An experimental bottom trawl survey was carried out in the Uganda sector of Lake Victoria during the period May 1993 through May 1995 with the aim of establishing the current composition, distribution and abundance of the fish stocks. A total of 205 successful one-hour hauls were taken using the 25.4mm mesh size codend trawl net during the 19 cruises. Fourteen fish taxa (excluding the haplochromines) were recorded with Lates niloticus constituting the bulk (97 %) of the fish retained. Haplochromines and L. nilolicus were encountered in all areas sampled while Nile tilapia (Oreochromis niloticus) and other tilapiines were restricted to waters less than 20 metres deep. An average catch of 154 kg/hr was obtained in waters less than 30 metres deep. Species diversity and relative abundance varied with depth. Only two of the fifteen fish taxa (haplochromines and L.niloticus) were recorded in waters deeper than 30 metres and the bulk of the fish by weight (92 %) was obtained in waters less than 30 metres.
