Interaction Between Aquaculture and Water Quality in On-Farm Irrigation Dams: Extended Monitoring and Mitigating Procedures to Manage Environmental Impact. de Wet,L.; du Buisson, B.; Holm, K.; Landsell, A.; Salie, K. & Snyman, B. Water Research Commission (2013).

Irrigation dams in the Western Cape Province (WCP) have a history of enrichment through external factors such as agriculture (fertilisers and pesticides), runoff and storm water from the surrounding areas and effluent from infrastructure extension (housing and informal settlements). The incorporation of aquaculture into such dams adds additional nutrients to the water column and sediment although the nutrients are not very concentrated. Irrigation dams can play a role in providing water bodies for floating net cage farming systems. However, the research found that water quality analyses over the research period indicated that farm dams in the WCP overall had good water quality, indicating that commercial crop farmers are exercising better management practices. The water quality was generally within the South African Water Quality Guidelines for agriculture, aquaculture and recreational use. The introduction of aquaculture under the prevailing farm dam water quality guidelines generally did not pollute the water to such an extent that crop farming was compromised. Thus, there is a case to be made for promoting integrated aquaculture-agriculture farming. Sustainability for both uses can be maintained through robust site selection and diligent hands-on management of both fish and crop farming operations. This approach will ensure that commercial crop farmers’ irrigation regime and yield quality is not negatively affected. Recommendations include prevention or minimisation of pollution through aquaculture in irrigation farm dams by means of effective technology transfer and knowledge dissemination.

Scoping study on the development and sustainable utilisation of inland fisheries in South Africa Volume 1: Research Report. Britz, P.J.; Hara, M.M.; Weyl, O.L.F.; Tapela, B.N. & Rouhani, Q.A. Water Research Commission (2015).

South Africa’s inland fishery resource endowment has been overlooked as a means of supporting sustainable livelihoods in the democratic era, lacking a guiding policy and legislation aligned with the country’s rights- based Constitution. The absence of an equitable inland fishing governance framework with defined use rights has resulted in growing unmanaged and unsustainable fishing practices, conflicts between resource users, and the perpetuation of Colonial- and Apartheid-era exclusion of rural communities from livelihood and economic opportunities linked to aquatic natural resources. In response to this problem, the Water Research Commission launched a solicited research project entitled “Baseline and scoping Study on the development and sustainable utilisation of storage dams for inland fisheries and their contribution to rural livelihoods” to provide a knowledge base to inform the development of policy and institutional arrangements for inland fishery governance.

Scoping study on the development and sustainable utilisation of inland fisheries in South Africa Volume 2: Research Report.Tapela, B.N. & Rouhani, Q.A. Water Research Commission (2015).

South Africa’s inland fishery resource endowment has been overlooked as a means of supporting sustainable livelihoods in the democratic era, lacking a guiding policy and legislation aligned with the country’s rights- based Constitution. The absence of an equitable inland fishing governance framework with defined use rights has resulted in growing unmanaged and unsustainable fishing practices, conflicts between resource users, and the perpetuation of Colonial- and Apartheid-era exclusion of rural communities from livelihood and economic opportunities linked to aquatic natural resources. In response to this problem, the Water Research Commission launched a solicited research project entitled “Baseline And Scoping Study On The Development And Sustainable Utilisation Of Storage Dams For Inland Fisheries And Their Contribution To Rural Livelihoods” to provide a knowledge base to inform the development of policy and institutional arrangements for inland fishery governance. The research approach consisted of a combination of literature reviews, community based surveys, fishery productivity modelling and stakeholder consultations. The available literature on South African inland fisheries was reviewed, access rights arrangements and legislation analysed with recommendations for reform, and the production potential of South African impoundments estimated using morpho-edaphic models. A research survey was conducted among selected fishing communities to evaluate the role of indigenous and local knowledge in inland fishery utilisation, and to characterise the role of inland fisheries in rural livelihoods. A series of consultations and workshops was conducted with rural fishing communities, mandated government department representatives, and recreational angling bodies. The results of the reviews and surveys were discussed with government departments to determine options for institutional and organisational arrangements. The organised recreational angling sector was presented with the project findings, and their views on inland fishery governance solicited. The institutional and organisational requirements for inland fisheries governance were then analysed based on the project research results, South African development and environmental policies, and internationally accepted fishery “good governance” norms. Recommendations for institutional and organisational arrangements were presented to the relevant government departments and feedback incorporated into the research reports.

Western Cape Aquaculture Market Analysis and Development Programme. Kaiser EDP & Enviro-fish Africa (2011).

This report captures the findings of the Western Cape aquaculture market development framework project. Within the context of emerging national and provincial aquaculture strategies, this project aims to support a shift from production-driven initiatives to a more market-oriented approach to aquaculture development in the province. More specifically, the findings of the project provide a platform for future developments and support to the sector to take into account market opportunities, market entry requirements and challenges.

The project takes a value chain approach to identifying opportunities and challenges – assessing all the activities from production through to reaching the consumer. Value chains covered within the project scope include abalone, bivalves, marine finfish, trout and Atlantic salmon, tilapia and ornamental fish.

The outputs are based on expert input, secondary research, in-depth local and international interviews, and quantitative analysis of trade flows, production and prices. The research was completed between January and March 2011.
