Results of a socio-economic survey on fish consumption and fishing

No results found.As part of the preparatory phase of ALCOM's Pilot Project on the Utilization of Small Water Bodies in Botswana, a socio-economic survey was carried out amongst communities living around seven selected dams in south-eastern Botswana. The main aims of the survey were to determine fish consumption patterns and attitudes as well as the types of fishermen and the level of their current activity. To implement the survey, two interview schedules were used, Survey 1 was designed to gather information of fish consumption patterns and Survey 2 was designed to gather information on fishermen/women. For Survey 1, a quasi-randomly selected sample of 343 households were interviewed on their fish consumption patterns. These interviews were carried out at households living around all seven dams. For Survey 2, as no information existed on the number of people fishing, anyone seen fishing, or was identified as a fishermen either from Survey 1 or through key informants, was interviewed. In total, 37 fishermen/women were interviewed. Results from Survey 1 show that approximately 20 % of the households interviewed have eaten fresh fish, albeit very rarely. The most common reason for not eating fresh fish was that it was not available to buy. The main source of fresh fish came from fishermen in the household catching fish in the dam. Tilapia (bream) is the preferred species, although barbel is also eaten. Households usually fry fish, but many sun-dry fish before cooking either because the taste is preferred or for preservation purposes. Fresh fish is usually not fed to weaning children as it is considered to have too many bones. The results also reveal that just over 80 % of the total sample eat tinned fish, usually tinned pilchards in chili sauce. Other types of fish such as frozen or salted fish are eaten by a negligible number of the households, because they are not easily available except in the larger supermarkets in main villages (frozen only). -

Report of activities towards fisheries exploitation, 1992-1993

No results found.ALCOM has been assisting the Fisheries Section, Ministry of Agriculture, Botswana in implementing the project “Development of small reservoir fisheries”. During phase one, a socio-economic survey around seven smaller reservoirs showed that there is sparse hook and line fishing on those reservoirs. The survey repudiated earlier assumptions that people in eastern Botswana do not eat fish and suggested that availability and knowledge concerning how to cook fish are the main constraints preventing people from eating more fish. The survey also concluded that fishing is a part-time activity. These findings led to the second phase with a biophysical study of eight selected reservoirs through test fishing using the Drottningholm method. A total of 15 different species were found; the CPUE was calculated both by species and by total catch for each reservoir. The catch was dominated in mass by Oreochromis andersonii in four reservoirs, by Clarias gariepinus in three and by small Barbus spp i n one reservoir. During the second phase, Semarule dam (37 ha when full) was chosen as a reference for a one-year test-fishing cycle. Five different species were found but catches were usually dominated in mass by O. andersonii. Seasonal changes could be registered. During the period October – December 1990 and September – October 1991 the catch was dominated by the small pelagic Barbus paludinosus. These two phases brought home the fact that fish are there but the stock is unexploited becau se of the lack of fishing knowledge of the local population who would like more fish if it was possible. ALCOM and the Fisheries Department therefore started a third phase in 1992 which focused more on exploitation of Small Water Bodies than on assessment. Through collaboration with the Water Development Section (WDS) in the Ministry of Agriculture (MoA), fisheries has now been included in the water development policy as an activity in multipurpose dams. -

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.
