1992 fisheries statistics, Lake Kariba - Zimbabwe shore

This statistical report covers catch records from the Zimbabwe part of Lake Kariba for the period 1974-1992. Landings, catches and fishing effort statistics are included for both the pelagic and the inshore artisanal fishing sectors.

1993 fisheries statistics, Lake Kariba - Zimbabwe shore

This statistical report covers catch records from the Zimbabwe part of Lake Kariba for the period 1974-1993. Landings, catches and fishing effort statistics are included for both the kapenta (pelagic) and the inshore artisanal fishing sectors.

1994 fisheries statistics, Lake Kariba - Zimbabwe shore

The report provides catch records for the Kapenta and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1994. Kapenta usually constitute about 90% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. Whereas kapenta represent a unit stock which is harvested by both Zimbabwe and Zambia, the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline, considered to be 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, Clarias gariepinus and Synodontis zambezensis.

1995 fisheries statistics, Lake Kariba - Zimbabwe shore

The report provides catch records for the Kapenta and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1995. Kapenta usually constitute about 90% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. Whereas kapenta represent a unit stock which is harvested by both Zimbabwe and Zambia, the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline, considered to be 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, Clarias gariepinus and Synodontis zambezensis.

1996 fisheries statistics, Lake Kariba - Zimbabwe shore

The report provides catch records for the Kapenta and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1996. Kapenta usually constitute about 90% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. Whereas kapenta represent a unit stock which is harvested by both Zimbabwe and Zambia, the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline, considered to be 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, Clarias gariepinus and Synodontis zambezensis.

1997 fisheries statistics, Lake Kariba - Zimbabwe shore

The report provides catch records for the kapenta (Limnothrissa miodon) and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1997. Kapenta usually constitute about 94% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. The kapenta, which occupy the open pelagic waters of the lake, represent a unit stock which is harvested by both Zimbabwe and Zambia; the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline. The Zambian and Zimbabwean inshore fisheries may therefore be considered to be exploiting 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, M.anguilloides and Clarias gariepinus.

1998 fisheries statistics, Lake Kariba - Zimbabwe shore

The report contains data, statistics and information for both the pelagic and inshore fisheries of Lake Kariba for the year 1998. Time series data and notes for the 2 fisheries are included. The pelagic fishery exploits kapenta, the freshwater sardine Limnothrissa miodon, and is carried out all year round using light for attracting the fish. Two types of fishing vessel designs are in use (the pontoon-catamarans and the displacement monohulls) and the type of gear used is the lift net. The inshore fishery distinguishes the fishery that uses gillnets and exploits the indigenous Zambezi River fish species. This fishery is restricted to the lakeshore and uses 3 types of boats - the dugout canoe, fibreglass and metal boats.

A review of the fisheries of the Uganda waters of Lake Albert East Africa, 1928-1965/66, with catch data mainly from 1953

An historical account is given of the development of the Lake Albert fisheries since Worthington's survey in 1928. It is noted that the development of the fisheries was related to, and dependent upon, improvements in the type of gear and canoes, an incFease in the number of canoes and outboard engines in use, improved marketing facilities and better road communications. Summarized data, collected mainly since 1954, has been analysed and tabulated to show annual exports to the Congo, total annual catches 'and annual catches of individual species. A change in the relative abundance of the various species in the annual catches is described. It is noted that this change was caused by a change-over from large to small mesh size gill-nets, and that it was associated with an increased demand within Uganda for the smaller species of fish, such as Aleste's baremose and Hydrocynus forskahlii. A brief description of fish processing and marketing in the Lake Albert region is given, which emphasizes the suitability of salt-cured fish to the social and physical environment of the area. Finally, a summary of a recent survey of the potential fish resources of the lake is given in the discussion, and estimates of the 1965 catch at the north and south ends of the lake are compared with the findings of the survey. This showed that there is little danger of overfishing the Alestes baremose stocks of the Wanseko area at the 1965 rate of exploitation of the species, and that the total catch for 1965 at the south end of the lake was well below the estimated annual sustainable yield from the area.

A report of the fisheries catch assessment surveys in the Ugandan waters of Lake Victoria for November 2005

The fisheries of Lake Victoria have undergone many changes in the recent past which have been characterized by shifts in abundance of different fish Species and changes in fishing effort. Monitoring of the population dynamics as well as the magnitude, distribution and trends of fishing effort and fish Catches is probably more necessary now than ever before for sound management of the fisheries of the lake. This will enable the formulation of appropriate fisheries policies and legislation to ensure that the fisheries are sustainable. One of the avenues to collect information to support the above process is through conducting regular Catch Assessment Surveys (CASs). The EU funded Implementation of a Fisheries Management Plan (IFMP) project for Lake Victoria through the Lake Victoria Fisheries Organization (LVFO) is supporting the implementation of regionally harmonized CASs in Lake Victoria. The CASs under IFMP are following a statistically design laid down in Standard Operating Procedures (SOPs) agreed around the whole lake. In the Ugandan part of the lake, the CASs are carried out at 54 fish landing sites selected in the eleven districts sharing the lake. They are jointly conducted by the Fisheries Resources Research Institute (FIRRI), Jinja; the Department of Fisheries Resources (DFR), Entebbe; and the Districts of Busia, Bugiri, Mayuge, Jinja, Mukono, Wakiso, Kampala, Mpigi, Masaka, Kalangala and Rakai. The CAS enumerators are recruited from the fishing communities and work under direct supervision of sub county Fisheries Officers. It is planned to involve the recently formed Beach Management Units (BMUs) in fisheries data collection when modalities for their roles have been streamlined.

A report of the Fisheries Catch Assessment Survey in the Ugandan waters of Lake Victoria for the August 2007 survey

The monitoring of fish stocks as well as the magnitude, distribution and trends of fishing effort and fish catches is required for sound fisheries resources management. Conducting regular Catch Assessment Surveys (CASs) in Lake Victoria is one of the ways through which the partner states sharing the lake are generating information to contribute to the above process. The EU funded Implementation of a Fisheries Management Plan (IFMP) project for Lake Victoria through the Lake Victoria Fisheries Organisation (LVFO) is supporting the implementation of regionally harmonised CASs in Lake Victoria . The CASs under IFMP are following a statistical design laid down in Standard Operating Procedures (SOPs) agreed by the three partner states of the East African Community sharing the lake. In the Ugandan part of the lake, the CASs are carried out at 54 fish landing sites selected in the eleven riparian districts sharing the lake. The National Fisheries Resources Research Institute (NAFIRRI), Jinja; the Department of Fisheries Resources (DFR), Entebbe; and the Districts of Busia, Bugiri, Mayuge, Jinja, Mukono, Wakiso, Kampala, Mpigi, Masaka, Kalangala and Rakai jointly conduct the surveys. The CAS enumerators are recruited from the fishing communities and work under direct supervision of subcounty Fisheries Officers. NaFIRRI seeks to continue strengthening the engagement of the Beach Management Units (BMUs) and other fisheries Co-management Institutions in fisheries data collection .

Final report of the fisheries catch assessment survey in the Ugandan waters of Lake Victoria for the May 2014 survey

This report presents findings of the CAS conducted in the Ugandan waters of Lake Victoria in December 2015. The results of the previous thirteen harmonized CASs conducted since July 2005 (July, August, September and November 2005; in March, August and December 2006; in March and August 2007; in February and December 2008; March 2010; May 2011 and May 2014) are included to show the emerging trends. The report also presents annual catch estimates for the Ugandan part of the lake from 2005 to 2015. This information together with other fish stock assessment and socio-economic monitoring survey data can now be utilized in the planning and management of the fisheries resources of Lake Victoria. The 2014 CAS results were very vital in the development of the Lake Victoria Fisheries Management Plan 2014.

The survey of Lake Victoria's fishers

The findings are presented of a survey conducted regarding the fishers of Lake Victoria, which examined the relationships affecting supply flows of raw material on to the market, and also the characteristics of fishing activities and their effects on fish quality and distribution. Fish marketing plays a vital role in the lives of much of the lake basin's population, both in terms of employment and nutrition. The results of the survey comprise, in part, a base-line data set which will facilitate further research, analysis and management decision-making in relation to stakeholders of the lake's resources. Data collection, methods and research difficulties encountered are described and details given of a profile of a boat owner/renter and aslo of a profile of a crew member. The survey shows that Lake Victoria's fishery is one of very limited diversity. The fishers recount that they consistently target one or more of the 3 most common species within the lake (Nile perch, tilapia and dagaa) and very rarely consider any other species type. The largest proportion of fishers on the lake are Nile perch fishers; there is considerable demand for this species, and hence fishers have little incentive to either target alternative fish species, not to try and establish firm marketing outlets through the creation of arrangements with their principal buyers. In Kenyan waters, however, the number of Nile perch fishers is equaled by the number of dagaa fishers; this fish now commands a considerable portion of the market for fish from Lake Victoria through its availability as well as its relatively low prices. The tilapia fishery is in decline, and all 3 riparian states would not appear to be attracting investment almost certainly as a result of declining catches. For many of those working in Lake Victoria's fishery, the problems faced appear most often to be associated with the vagaries of an unstable market which may rise or fall depending on the state of the international market or the state of access roads to fish landings.

Water quality and nutrient dynamics - Lake Victoria, Kenya

Limnological studies in Lake Victoria (Kenyan portion) have been sporadic. Water quality and nutrient dynamics studies are being undertaken in fifteen sampling sites that have been divided into four ecological zones namely: Nyanza Gulf, Rusinga Channel, open waters inshore and open waters. The ongoing study will show how the physical and chemical paramenters affect fish distribution and abundance.

SEDAWOG, 2000. Fisheries co-management options at Kiumba Beach: a participatory pilot study

This report represents the key output of a training workshop hosted by Lake Victoria Fisheries Research Project (LVFRP) for researchers from each of the riparian countries fisheries research institutes. The workshop aimed to train the researchers in participatory research techniques which they could use to undertake a study of community-based institutions and organizations which could potentially be involved in fisheries co-management. A central focus of the workshop was a study to identify the community-based organizations and institutions, which operated at Kiumba beach, and this study is reported here. Separate reports, which include operated at Kiumba beach and this study is reported here. Separate reports, which include details of the training process and the participatory methods used, are available (Sarch 1995, 2000). The report centers on the information generated from the participatory pilot study conducted by the workshop participants and the community at Kiumba Beach over the course of a week in March 2000. Ranges of participatory research techniques were used and the discussion and diagrams, which resulted from them, form the basis of this report. The workshop participants undertook a preliminary analysis of these findings and this has been synthesized at the end of this report. (PDF contains 55 pages)
