Lakes and Water Management: Proceedings of the 30 Years Jubilee Symposium of the Finnish Limnological Society, held in Helsinki, Finland, 2223 Septem [Paperback]

Multiple use of natural waters and watersheds poses many practical problems, some of which are clearly limnological, relating for example to carrying capacities oflakes, deterioration of water quality and fisheries management. It is thus important to consider limnological aspects when making decisions in the field of water management. To further this attitude the Finnish Limnological Society considered 'Lakes and Water Management' to be a suitable theme for the Society's Jubilee Symposium, held in Helsinki on 22-23 September, 1980 at the Viikki Campus of the University of Helsinki, to mark the Society's 30th Anniversary. The Finnish Limnological Society has arranged nationallimnological symposia everyone or two years. The papers presented at these symposia have been published in the series 'Limnologisymposion' (in Finnish or Swedish, with short summaries in an internationally spoken language). Due to financial difficulties, the series was terminated as of the symposium in 1979. When preparing the 30th Anniversary of the Finnish Limnological Society, the Governing Board of the Society decided to arrange an international symposium on a theme relevant to modern limnology both in Finland and elsewhere. The selected results of the successful meeting on lakes and water management, which was attended by 220 people from 7 countries, are presented in this volume.The first half century of limnology in Finland.- One: Structure and Function of Lake Ecosystems.- 1.1 Unpolluted waters.- Dynamics of phytoplankton in Finnish lakes.- Dispersion patterns of phytoplankton in lakes.- On the annual variation of phytoplankton biomass in Finnish inland waters.- Dynamics of phytoplankton in the brackish-water inlet Pojoviken, southern coast of Finland.- Carbon, phosphorus and nitrogen budgets of the littoral Equisetum belt in an oligotrophic lake.- The diversity, biomass and production of zooplankton in Lake Inarij?rvi.- The food and parasites of fish in some deep basins of northern L.
