Recent trends in research on Lake Victoria fisheries. Proceedings of the Second EEC Regional Seminar on Recent Trends of Research on Lake Victoria Fisheries, organized and hosted by Kenya Marine and Fisheries Research Institute (KMFRI), 25-27 September 1991, Kisumu, Kenya
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Okemwa, E.; Wakwabi, E.; Getabu, A.
Topics on Lake Victoria limnology, benthic fauna, stock assessment, catch assessment survey, gear selectivity, fisheries ecology, fish parasites and marketing economics are covered. Management and conservation of the lake's fisheries and other aquatic resources are discussed. Dialogue between fishermen, scientists and administrators is stressed, measures to be undertaken are addressed and further research is recommended.

Mortality rate, exploitation and recruitment in Oreochromis niloticus (Linnaeus) in Nyanza Gulf of Lake Victoria, Kenya
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Getabu, A.
An analysis was done on length frequency data to study mortality,     exploitation rate and recruitment in Oreochromis niloticus in Nyanza     Gulf, Lake Victoria. The fishing mortality (F) and natural mortality     (M) were 0.468 y super(-1) and 2.0 y super(-1) respectively. The     exploitation rate was 57.2%. Yield per recruit under the fishing     regime was 250 g. Its predicted value at maximum sustained yield was     530 g, which could be obtained at a fishing mortality of 1.5 y     super(-1). The recommended value was 500 g to be obtained at a fishing     mortality of 1.0 y super(-1). The maximum biomass per recruit (B/R)     was 1132.48 g while the optimum was 1068.38 g. The biomass recruit     under the present fishing regime is 534.19 g which is...

Multigear fishery of Nile perch (Lates niloticus) in the Winam Gulf of Lake Victoria: with special reference to mortality, selection and catch/effort data

Autores: Manyala, J.O.; Rabuor, C.O.
A survey of multigear fishery of Nile perch (Lates niloticus) in the     Winam Gulf of Lake Victoria indicates that total mortality coefficient     (Z) determined from longline fishery using hook number 6 was double     that of hook number 7. Total mortality coefficient determined from     gillnets and beachseines were lower than those of hooks. The catch per     unit effort (C/f) measured using different criteria indicated an     increase for all gears in 1990 as compared to 1989 except for     gillnets. A two-fold increase in unit effort (f) increased the C/f for     mosquito seines by only 30%. The typical exponential decay of C/f with     increasing f of exploited stock in equilibrium was lacking in the case     of Nile perch in the Winam Gulf.

Distribution of economic benefits from the fisheries of Lake Victoria
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Abila, R.O.; Odongkara, K.O.; Onyango, P.O.
The Lake Victoria fishery contributes immensely to the socio-economic development of the riparian states. The East African Community has designated the lake basin as an ‘economic growth zone’, with the potential to develop into a major economic region. The fisheries are vital in creating employment opportunities, mostly rural-based, thereby helping to reduce rural-urban migration. Fish is also a rich source of animal protein for human consumption and provides raw material (fishmeal) for processing animal feeds. The fish industry contributes to GDP and has continued to be an important source of foreign exchange earned from fish exports. Besides, the fish industry contributes to the national and local government revenues through levying of various taxes,...

Conseil interminstériel sur la pêche et l'aquaculture
Provedor de dados: Ocean Docs: e-repository of  publications
La pêche est une composante essentielle du développement économique et social intégré. Elle contribue de manière non négligeable aux objectifs de croissance de l'économie nationale, notamment à la réduction du déficit de la balance des paiements, du chômage ainsi qu'a la satisfaction des besoins alimentaires des populations.
