Book (series)Report on the Bioeconomic Modelling of Kapenta Fisheries on Lake Kariba
GCP/RAF/466/EC SmartFish Project
2013Also available in:
No results found.This work on the bioeconomic modelling of the Kapenta fishery on Lake Kariba was conducted as part of a process of joint fisheries management of the fishery between the Governments of Zimbabwe and Zambia, and was supported by the IOC-SmartFish Project under its Fisheries management component (UNFAO). The first part of the report provides an overview of the Kapenta fishery: information about the bioecology of this resource; harvesting systems in operation on the Lake; management systems in both c ountries; as well as some elements of processing and marketing. The second part concerns the biological modelling. A summary of the work that has already been done is provided, together with an assessment of available data. Based on the information available, the dynamic population model was chosen and used (surplus production model of Fox 1970). Thereafter, the results of the biological modelling are presented and discussed. The third section of the report concerns the development of the econom ic part of the model. Previous economic assessments of Kapenta fisheries have been summarized. The results of the Economic Survey, carried out in 2013 to support the bioeconomic modelling exercise, are put forward. Assumptions and analyses to develop the economic part of the model (modelling demand and costs) are also presented in detail. Finally, the fourth section of the document details the bioeconomic model: the way it works and its results. This bioeconomic modelling exercise shows that in 2011, the Kapenta resource was overexploited with an excess of fishing effort of about 40 percent. Fisheries were operating almost at a situation of open-access equilibrium where the rent of the resource is fully dissipated. As a consequence, the fishing industry is achieving very poor economic returns and faced with numerous challenges, is also demonstrating a low level of sustainability. Other main findings of this report concern the overall performance of the Kapenta fishery: the potential of wealth for economic growth, in terms of rent (estimated at approximately US $24 million per year), is completely lost for the economy of both countries; Kapenta resource productivity and thus fisheries production is negatively affected due to overexploitation, in turn leading to a negative impact on the food security status of those consumers who strongly depend on Kapenta in their diet. The fisheries generate a substantial amount of ‘on-board’ work (crew), however, remuneration for this type o f labour tends to be very low compared to national wage standards. Furthermore, lower levels of production have no doubt had a negative impact on employment in Kapenta processing activities that take place along the lakeshore. This situation requires further study, during the Bioeconomic Working Group, and should be based on information provided by the industry on processing activities. In addition to the diagnosis of the Kapenta fisheries and the economic situation of the industry in 2011, this report illustrates the potential of the model in terms of simulation for management purposes and its prospects for development. 5 The main recommendations of this study concern how to improve the bioeconomic model that has been developed. Thus these recommendations are mainly focused on the need to improve the information necessary feed and to develop the model. Recommended approaches will require strengthening partnerships with the industry. -

No results found.This document is the final report of the second Technical Consultation on the Development and Management of the Fisheries of Lake Kariba. The major topics discussed were an overview on the importance of co-management as a tool for sustainable fisheries management and development in Zambia and Zimbabwe; fishers’ views on the importance of the kapenta fishery and the artisanal fishery; status of fisheries on the Zambia and Zimbabwe side of Lake Kariba; and an overview on the management and develop ment of the fisheries of Lake Kariba. The summary of the main recommendations and decisions is shown in Appendix D. -
ProjectEconomic appraisal of the pelagic fishery of Lake Kariba. A preliminary report. 1992
Also available in:
No results found.The IFIP project started in January 1989 with the main objective of promoting a more effective and rational exploitation of the fisheries resources of major water bodies of Eastern, Central and Southern Africa. The project is executed by the Food and Agriculture Organisation of the United Nations (FAO), and funded by the United Nations Development Programme (UNDP)for a duration of four years.There are eleven countries and three intergovernmental organisations participating in the project: Bu rundi, Ethiopia, Kenya, Malawi, Mozambique, Uganda, Rwanda, Tanzania, Zambia, Zaire, Zimbabwe, The Communaute' Economique des Pays des Grands Lacs (CEPGL), The Preferential Trade Area for Eastern and Southern African States (PTA) and the Southern African Development Coordination Conference (SADCC). The immediate objectives of the project are: (i) to strengthen regional collaboration for the rational development and management of inland fisheries, particularly with respect to shared water bodies; (ii) to provide advisory services and assist Governments in sectoral and project planning; (iii) to strengthen technical capabilities through training; and (iv) to establish a regional information base.
