Evaluations of the pelagic resources in the Burundi waters of Lake Tanganyika and the evolution of the fisheries

The important pelagic fishery resources of northern Lake Tanganyika were identified after a preliminary scientific evaluation, and in Burundi, with governmental assistance they were rapidly developed and exploited more intensively until overfishing was thought to have occurred. At this point, legal measures were introduced in order to protect the resource by restricting fishing effort and maintaining the total yield near the apparent maximum sustained limit. Complementary biological research on the fish stocks did not accompany the rapid fishery development and now an intensive stock assessment programme has been launched by the Government and UNDP in order to define more precisely the available fish stocks and to consider, with the co-operation of the neighbouring lacustrine states, suitable ways of ensuring optimum levels of fish harvest from year to year.

Fishery resources and some economic aspects of four fishing villages on Lakes George and Edward in the Queen Elizabeth National Park, Uganda

The fishery resources of Lake George and Ugandan waters of Lake Edward are described. The main fish species currently observed in the commercial catches were determined and the reasons of changes in species composition of the catches. that occurred in the recent years, are explained. The fishing activity and some economic and nutritional aspects of four fishing villages, selected among the ten present within the Queen Elizabeth National Park boundaries, are analyzed, In the end some suggestions are given for management of the fishery resources of these lakes.

Lakes Wamala and Kijanebalola: evaluation of the fisheries resources during July 1975

This report presents the results of the second (in 1975) fisheries resource survey for Lake Wamala conducted from 10th to 16th July 1975. The first similar survey covered the period 14th to 20th May 1975. The areas sampled consisted of the river-month areas, the papyrus-fringed inshore waters and the open dee offshore waters. In an effort to find the possible major causes of the decline in catch and seasonal disappearance of fish-hence a solution to the problem(s)-a second fisheries resource survey using multifilament nylon gillnets was conducted on Lake Kijanebalola during the period 17th to 21st July 1975. The first survey was similar and covered the period 21st to 27th May 1975.
