No Thumbnail AvailableDocumentNon-thematic issue 1999This issue of Unasylva contains, as promised in the previous edition, additional articles on sustainable mountain development. These articles help to complete the focus on the topic and should also help to promote interest in the recently declared International Year of the Mountain (2000) for which FAO has been designated lead agency status within the United Nations system.

Book (series)Bioeconomic Analysis of the Kapenta Fisheries. Lake Kariba, Zimbabwe and Zambia

No results found.FAO supports a joint management process and the development of fisheries on Lake Kariba between Zimbabwe and Zambia. The 4th Technical Consultation Meeting, held in Kariba in 2010, recommended the development of bioeconomic modelling of Kapenta fishery (Limnothrissa miodon). In support of this recommendation, a first field mission was conducted in November 2012 with the support of the SmartFish project. The objective of this mission was to meet with key stakeholders in the public and private sec tors involved in the Kapenta fishery in the two countries in order to: inform them about the bioeconomic assessment exercise to be carried out on the Kapenta fishery; underline the importance of their collaboration, in particular the provision of reliable data to fit the model; find out more about the Kapenta fishery and current challenges; gather key documents and information required for the bioeconomic modelling; assess the quality of information requested for the bioeconomic modell ing and identify any gaps; draft the Terms of Reference for National Consultants who will be responsible for the collection of additional information after the mission. Based on meetings with key officials in charge of the management of the fisheries and with leaders of fishing enterprises in the two countries, the main results of the mission indicate that: The fishing capacities in the Kapenta fishery have greatly increased since the early 2000s, from approximately 600 rigs allowed on the l ake in 1999 to 1,098 in 2012 (5th Technical Consultation Meeting, 2012). There are also an unknown number of unregistered and unlicensed rigs (illegal, unreported and unregulated fishing); The fishing effort, reported by the fishing companies, has subsequently increased dramatically (40 percent increase between 2000 and 2011); The management system in the two countries is based on a licensing system and the payment of an annual fee for access to the fishery, as well as several technical mana gement measures (mesh size, zoning, and brief closures based on the lunar calendar). The industry is also obliged to record and transfer to the management authorities monthly data on their catch and fishing effort. In practice, it seems that there are no real access controls and poor enforcement of regulations. Thus, the fishery currently appears to be open and free for all.  4  The harvesting systems and the technical productivity of fleets in the two countries are relatively homogeneous. C atches per unit of effort have fallen by 35 to 50 percent since 2005; Qualitative indicators based on the situation of fishing enterprises show that the Kapenta fishery is overfished and revenue from resources is widely dissipated; Statistical data available on effort, catch and CPUE, as well as scientific knowledge on biological parameters of the Kapenta stock suggest that only a biological modelling based on a surplus production model (such as Schaeffer, Fox, etc.) is possible; There is an important shortage of economic data on time series concerning ex- vessel prices, costs related to the activities of fishing enterprises, their investment, and their profitability. Consequently, the work of two national consultants to support this process will mainly be focused on the collection of economic data in order to estimate an average cost per unit of effort (night fished per rig) in each country and for each fishing zone. Key documents for the bioeconomic modelling were collected bef ore and during the mission (or just after). A complete list of these documents can be found in Annex C. These key documents and references will form the basis of bibliographical references for the modelling exercise. A questionnaire was developed to collect missing information for the bioeconomic modelling exercise (Annex E). This information was obtained from a field survey and from a sample of fishing companies of different sizes and operating in different fishing areas (Basin/Stratum) in the two countries. A sampling plan was made on the basis of data from the frame survey undertaken with FAO support in 2011. However, it is strongly suggested that this economic fieldwork will be conducted in close cooperation with those responsible for the Kapenta producer organizations in Zambia and Zimbabwe; on one hand for the selection of those companies to be interviewed and to facilitate contacts, and on the other hand, to ensure the quality of data to be collected and transmitted. Forthcoming steps for the continuation of the process leading to the bio economic modeling workshop were also defined, as well the format of the workshop. -

No results found.Though Zimbabwe has few traditions as a “fish eating” nation, with the opening of Lake Kariba over three decades ago a fisheries industry was started. It has recently been realised that, in order to boost this industry, and to keep pace with the rising demands for fish, the many small dams in the country (over 12 500), which are used presently mostly for livestock and irrigation, could usefully be exploited. As well as food protein, jobs and alternative income sources would be created, especiall y in the rural communal areas. The Min. of Natural Resources and Tourism (MNR) has overall control of the larger water bodies and fisheries in Zimbabwe, and the Dept. of Agriculture, Technical and Extension Services (AGRITEX) oversees activities involving use of the small dams. It operates a small Fisheries Unit (FU) who have responsibility for fostering fisheries development. As a possible practical measure which could contribute to better management of this development, it has been suggested that a Geographical Information System (GIS) be installed. Apart from working out the most appropriate “level” for the installation of the GIS, the terms of reference (TOR) for this consultancy also sought to formulate proper objectives for a FU - GIS; to estimate the availability and quality of data obtainable; to establish the time necessary to collect and compile this; to work out whether there were advantages in adding nutritional data to a FU - GIS and to forecast the results which could b e obtained from a GIS. A total of 15 specific uses for a GIS were formulated and these would basically help to:- provide a spatially related management function, carry out development and/or planning functions, build up a temporal scenario of trends and developments.
