• Combining fisheries catching statistics and hydroacoustic method, an ecological monitoring of fish resources' (fish in aggregating cage was exclusive of fish resources after the fishery driving) catching and stocking in Lake Tianmu was carried out in three fishing stages, before the fishing driving (December 2011), after the fishing driving (January 2012) and after the fishing catching and stocking (March 2012). And then fish population structure, size component, fish density, fish aggregation, fish biomass and its distribution were gained with developing GIS model, which could provide scientific basis to the implementation of aquatic environment protection oriented fishery and fisheries production in Lake Tianmu.
