    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.

    The current interest in small water bodies derives mainly from their utilization for fisheries enhancement, which involves guidance on stocking, exploitation and species management in order to obtain optimum yield on a sustainable basis. The present study is an attempt to probe into the national experience in management of small water bodies in a selected few tropical countries with a view to gauging the resource size and assessing the strength, weaknesses and issues involved in their management from a global perspective in order to facilitate bilateral or multilateral interaction among nations displaying similar characteristics. This report provides an overview of the small water bodies and their fisheries in southern Africa, Asia and Latin America, represented by Zimbabwe, India, Thailand, Sri Lanka, Brazil, Cuba and Mexico. It depends heavily on the secondary data collected from various government agencies of the countries. A main constraint has been the remote and nondescript nat ure of the resources, the details of which, if available, were scattered among various agencies. Nevertheless, major facets of fisheries management in small water bodies in the seven countries have been highlighted. The main emphasis was on the resource size, organization of fisheries, fisheries management and species management, depending on the availability of data and information. An endeavour has also been made to offer policy prescriptions of operational significance for streamlining the fi shery management of small water bodies, particularly the reservoirs and other man-made impoundments which have promising fishery potential.
