|This paper deals systematically with economic development, evolutionary chronologyproduction type，fishery planning and economics，major propagationaland cultural technologies of reservoir fisheries in China. Furthermore it primarily analyzes the existingproblems about reservoir fisheries , and predicts the trend in reservoir fisheries.Since the 1950's all the development procedures of reservoir fisheries have experienced three phases:initation，development and rapid development. Hitherto，the production types of natural propagation，extensive stuck and integrated farming have been formulated;a lot of experiences in propagation technologies，artificial stock , transplant and domestication of exotic fish species，and control of some predacious fishes have been accumulated;semi-intensive and intensive culture means，net cage，enrichment culture and flowing water culture and so on， have been summed up. The existing problems of reservoir fisheries in China include simple fish population structure，clumsiness of other usages and fisheries employment，lower exhensive ecological efficiency，difficulties in catching bottom fishes，lower efficiency and higher cost of artificial food，lack of studies on theoretical problems related to reservoir fisheries. Reservoir fisheries in China have great potentialities，their development should give coordination of integrated culture and preservation of water quality in order to realize higher production，higher value and higher efficiency of ecological fisheries.
