PESCA

PESCA is regional project developing a decision support tool (DST) and best management practices (BMPs) to guide improvement of policies to increase fish production through cage aquaculture with negligible impacts on the water environment of the African Great Lakes (AGLs) and promoting use of those practices through adaptive research . The project is implemented in the Ugandan, Kenyan and Tanzanian parts of Lake Victoria, Lake Albert, Lake Edward, Lake Kivu, and the Malawian and Mozambican parts of Lake Malawi/Nyasa/ Niassa. It is coordinated by the National Fisheries Resources Research Institute (NaFIRRI) and implemented with partners from: Kenya Marine and Fisheries Research Institute (KMFRI), Kenya; Tanzania Fisheries Research Institute (TAFIRI), Tanzania; Department of Fisheries, Malawi; IIP - Fisheries Research Institute, Mozambique; Rwanda Agriculture Board (RAB) / Research Department; and Source of the Nile (SoN) Fish Farm Ltd, Uganda. These are supported by experts from: Great Lakes Fishery Commission, USA; Cornell University, Atkinson Center for a Sustainable Future and Department of Ecology and Evolutionary Biology, USA; and Hull International Fisheries Institute (HIFI), University of Hull, UK. The project is supported by the African Great Lakes Conservation Fund administered by The Nature Conservancy with funding provided by John D. and Catherine T. MacArthur Foundation to accomplish key priority issues coming out of the 2017 African Great Lakes Conference held in Entebbe, Uganda. Interested technical persons, institutions, and development partners are encouraged to join the project to contribute to development of this emerging industry.

Background

The AGLs are important sources of fish which supports livelihoods of about 1.8 million people and are hotspots of high fish biodiversity, especially Haplochromine cichlids of ecological and scientific importance. However most economically important capture fisheries of these lakes have declined due to overfishing and degradation of the fish habitats and can no longer meet the increased demand for fish by the rapidly increasing human population.

Benefits

Cage aquaculture which involves growing fish in cages suspended in water, while maintaining free exchange of water between the enclosure and the water body started on Lake Malawi in 2004 and Victoria in 2006 and has spread rapidly to other AGLs. There are over 5000 cages on Victoria, about 10 cages on Tanganyika, 400 cages on Kivu, 50 cages on Malawi/Nyassa/Niassa. Cage aquaculture has in less than 20 years, demonstrated capacity to increase fish production to more than 40 kg m-3 compared to less than 2 kg m-3 from land based aquaculture which started in the AGL region more than 60 years ago. Cages have a higher production per unit volume and lower construction costs compared to land based systems targeting the same production. Fish survival rate is high. On-farm operations such as handling and harvesting are more efficient and there are high returns on investments. Cage aquaculture can, however cause pollution of the water body from uneaten feed, excreta and dead fish, may disrupt biodiversity, result in disease outbreak and interfere with other lake uses such as navigation. It therefore needs proper guidance to safeguard the integrity of the water body. There are, however, no lake-specific BMPs and adequate policies to ensure long-term socio-economic and environmental sustainability cage aquaculture on the AGLs.

Overall Objective

Increase fish production and profitability through cage aquaculture with minimal impacts on the aquatic environment and other lakes uses

Specific Objectives

1. Develop a DST and BMPs to guide establishment, operation and monitoring of cage aquaculture in the AGLs.
2. Establish an African Great Lakes Cage Aquaculture Network (AGL-CAN) of Partners
3. Examine and share information from individual AGLs including: Tradeoffs between capture fisheries, other socio-economic uses of water bodies, the aquatic environmental health and cage aquaculture.
4. Provide guidelines for planning and operation of cage aquaculture farms.
5. Examine policy, regulatory, and human resources requirements and recommend improvements.
6. Guide monitoring and management of the environment of cage aquaculture farms
7. Increase awareness; and Work with farmer groups to test the DST and BMPs.

PESCA relies heavily on geospatial data and tools as basis for the decision support tool and BMPs. The data and tools are under development and will be provided as they become available.

Available is a tool (under development) that enables visualisation of localities of existing cage culture installations on selected African water bodies. You can view these installations by zooming in on any of the locations.

This tool is useful for prospetive farmers to identify already occupied sites or farms to avoid conflicts an/or stimulate colloboration and farmer to farmer cross learning and consultation. For cage fish farming development, it enables the anticipation of potential impacts of the installations on biodversity and water environment, thus supporting policy development and guidance..
