About this book

Although the selection of aquatic organisms to be cultured for food or other purposes is dependent, in different regions of the world, upon traditions, food preferences and local availability, nevertheless the trend worldwide is to shift from an empirical approach towards sound scientific management. This volume on managed aquatic ecosystems describes several aquatic management practices representing different geographical areas and cultural backgrounds. These range from the age-old carp culture and management in Europe and other continents to the more recent intensive management and mass culture of autotrophic micro-algae. Other chapters describe oyster culture in coastal Japan, and the management of man-made reservoirs in India. The overall thrust of the volume is an ecosystem approach. The authors have provided data on the structural and functional aspects of each of the habitats, and brought out the interrelationships between various factors in the context of the species culture. Thus the volume represents a departure from more conventional, production-oriented treatment of the topics.
