Although the concept of ecosystem regulation and stability has been well known among ecologists, they still have limited information on ecological processes to maintain ecosystem stability under changing conditions. With the pressing need for effective approaches to the suitable management of natural environments, it is of lasting importance to provide information on the ecosystem regulation processes to maintain ecological stability. This book presents a series of 30 papers summarising the results of the seventeen series of experiments using mesocosms carried out during three years in Lake Suwa. As procedure to analyse ecosystem regulation in aquatic environments, the experimental analysis using large enclosures placed in a lake is one of the reliable methods. Based on this idea, a series of experimental studies was conducted using six large mesocosms (5 m x 5 m x 4 m depth) settled in shallow eutrophic Lake Suwa in central Japan. The mesocosm size of 100 tons each was the minimum to enable normal growth of the planktivorous fish Hypomesus transpacificicus (pond smelt).
