Sustainable Fisheries and Aquaculture: Challenges and Prospects for the Blue Bioeconomy (Environmental Science and Engineering)

The book presents expert assessments of modern opportunities for fisheries and aquaculture in terms of economic efficiency, the state of fishery reservoirs, and the state of ichthyocenoses. The purpose of this book is to provide interested parties (government bodies, representatives of business, science and civil society) with information about modern solutions in the field of aquatic biological resources management, the state of aquatic ecosystems and fish stocks, and modern and promising technologies in aquaculture and fisheries. The book contains an assessment of the state and recommendations for the restoration of natural aquatic ecosystems, an analysis of the state of fisheries and aquaculture in inland waters, taking into account regional characteristics, the development of a methodology for assessing freshwater fish stocks, information on advanced technologies in cage aquaculture in reservoirs and lakes and in circulation systems, data on opportunities for capacity building in small-scale fisheries, and the prospects for establishing a data and information management system for fisheries and aquaculture.
