Little attention has been paid to rivers and it is only recently that a general awareness has developed of the importance of river systems to fisheries throughout the world. While rivers were relatively unaltered, the fish they produced was taken for granted, but with increasing competition for water for agricultural, industrial and domestic uses, fisheries usually have been given a secondary role among the range of users. The river systems themselves are being increasingly modified both in their form and in their flood characteristics. As a consequence, fish populations are being altered and productive capacities lowered. FAO is now called upon to advise countries on the ways in which such fisheries can be managed, both on their own and in harmony with such activities as irrigation, flood control or power generation. In trying to fulfil this task, we are limited by the comparative lack of knowledge about the systems under consideration. A meeting of experts was convened in an attempt to define the methodologies for the assessment of fishery resources in rivers and the use of these methodologies in evaluating the impacts of fisheries and other uses of the aquatic environment on the fishery.

A considerable quantity of data and information were collected on many aspects of the systems of the three reservoirs, including hydrological, biophysical and limnological features, primary production, and fish and fisheries data. This information was condensed and synthesized with the aim of providing a baseline against which the ecological changes that have taken place since impoundment can be described and analysed. Efforts are made to explain changes in fish catch in relation to climatic variations, ecological succession and fishing effort. The review shows that biological data and information are generally available. However, as is also common elsewhere, all three cases suffer from the general tendency to isolate and compartmentalize research into separate disciplines.

In this edited work, international experts in fisheries management and ecology review and appraise the status of river fisheries, assessment methodology, constraints on development, issues and options regarding management and associated problems in both temperate and tropical countries. Recommendations are made to improve management and an attempt is made to provide guidelines for formulating policy, for planning methodology and for evaluating future activities. Assessment of fish community structure and dynamics. Factors constraining stock recruitment. Fish habitat requirements. Instream flow needs. Impact of water resource schemes. Rehabilitation of river fisheries. Enhancement of fish stocks. Exploitation of stocks. Management of migratory fish stocks. Conservation of endangered species. Integrated river management. Bioeconomic issues. Legislation. Multinational management of rivers. Case studies.

The main objectives of LARS were 1) To produce reliable estimates of fish yield by: a) reviewing existing estimators of production and standing stocks in large rivers and b) summarizing current river inventory and assessment techniques for biotic and abiotic variables; 2) To publish the case studies and synthesis papers; 3) To identify areas requiring further study to improve river resource management; and 4) To improve communication and liaison between scientists in research and management, university and government.
