Development of design and construction of fishing boats in Uganda

Fishing boats and canoes varied very little in Uganda from the middle of the 19th century umil 1949. types in use being the Dug Out Canoe. up to 40 ft. in length with 4 ft. beam hollowed from trees, and "Sesse" canoes which were used on Lake Victoria; these had an obvious Arab influence. The length of the "Sesse" in recent years as from about 1912 is 28 ft., and it is used as an open fishing craft.

Development of the 28-foot inboard-engined fishing boat in Uganda

With the encouraging results of trawling experiments in Lake Victoria, it became apparent early in 1969 that commercial trawling on Lake Victoria might well be a viable economic enterprise. Considerable discussion about the optimum size and type of fishing vessel ensued, and the Fisheries Department decided to commission a number of different prototypes for comparative trials.

Fishing gear selectivity in relation to their manufacture and to the management of fisheries of the Nile perch, the Nile tilapia, and Rastrineobola argentea (Mukene) in Lakes Victoria and Kyoga

The fisheries of Lakes Victoria and Kyoga have changed from the native tilapiine species and are now dominated by two introduced species; Nile perch and Nile tilapia, and one native species; Rastrineobola argentea (mukene). Because of the differences in the size of the species, it may be necessary to change the type and sizes of nets used.

No turning back: Indonesia, illegal fishing

Despite official legislation, Indonesia is yet to institute processes to curb illegal, unreported and unregulated (IUU) fishing.

A description of certain indigenous fishing methods from Southern Dahomey

A survey of certain Dahomean fishing methods showed them to be specifically adapted to the exploitation of floodplains and shallow water lagoons. Several types of fish-parks are described, ranging from small installations thaI funclion as refuge traps, to larger constructions that act as a form of fish culture. Ponds are also dug in the floodplains in order to conserve fish isolated during the dry season. These methods all give high yields and are worthy of consideration for use elsewhere on the African continent.

The increased fishing pressure and the future of the fish stocks of Lake Victoria, Uganda

The Uganda sector of Lake Victoria occupies 29,580 km2 (43%). The lake used to boast of a multi-species fishery but presently relies on three major species Lates niloticus, Oreochromis niloticus and Rastrineobola argentea. During the past decade the total fish production on the Ugandan sector increased drastically from 17,000 tonnes in 1981 to about 13,000 tonnes 1991, indicating a healthy state of the fishery. This was contributed by a combination of factors including the explosive establishment of the introduced L. niloticus which contributed 60.8% in 1991 and the increase in the number of fishing canoes from 3470 in 1988 to 8000 in 1990. Isolated fishery resources studies carried out in different areas of the lake since 1971 seem, however, to indicate contrary trends in the available stocks and, therefore, the status of the fishery. In the experimental fishery, continued decline in catch rates have been recorded. Similarly, in the commercial fishery catch per unit of effort has been considerably poor (33 kg per canoe during January - March 1992) and the average size of individual fish laRded continued to decline, obviously pointing at possible over-fishing. This, therefore, calls for further urgent research on the available stocks for proper management strategies to be formulated.

A conceptualized fishing system for the African environment with a comparative approach

The paper examines a conceptualized fishing system for the African Environment with a comparative approach. Although the fishing system has been conceived as a bio-economic complex, emphasis will be given to the explanation of the detailed structure and functioning of the system. Subsequent synthesis involving the use of existing relationships for management etc. will also be undertaken. The proposed fishing system is conceptually feasible in an ideal environment with adequate monitored data and organized fishing, however it is anticipated that the African environment will not satisfy such conditions.

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.

A note on the commercial and sport fishing for some of the major scombroid fishes and wahoo on the Kenya coast

Commercial seerfish and wahoo catches were examined monthly during 1973 and 1974 at Malindi fish market where also fish from Ngomeni, Nambrui, Watamu and Kilifi were landed. Annual commercial catch data was compiled from Kenya Government Fisheries records at Malindi for 1973 and 1974. Sport fishing data was compiled from Angling Club log books at Bakari and outrigger clubs at Mombasa.
