Aquaculture is a rapidly growing, successful approach to improving diets by providing more high quality fish and shellfish protein. It is also an industry with major unresolved issues because of its negative impact on the environment. This book is a pioneering effort in the development of environmentally benign aquaculture methods.
This book is open access under a CC BY 4.0 license. This volume addresses the potential for combining large-scale marine aquaculture of macroalgae, molluscs, crustaceans, and finfish, with offshore structures, primarily those associated with energy production, such as wind turbines and oil-drilling platforms. The volume offers a comprehensive overview and includes chapters on policy, science, engineering, and economic aspects to make this concept a reality. The compilation of chapters authored by internationally recognized researchers across the globe addresses the theoretical and practical aspects of multi-use, and presents case studies of research, development, and demonstration-scale installations in the US and EU.
It is also recommended that efforts be increased to farm lower trophic levels species and optimize feeds and feeding in order to minimize ecosystems impacts and ensure long-term sustainability. Similarly, risk assessments and/or environmental impact assessment and monitoring must always be in place before establishing offshore farms, and permanent environmental monitoring must be ensured. All coastal nations should be prepared to engage actively in developing the technological, legal and financial frameworks needed to support the future development of offshore mariculture to meet global food needs. The workshop report highlights the major opportunities and challenges for a sustainable mariculture industry to grow and further expand off the coast.
This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.
This report explores the growth prospects for the ocean economy, its capacity for future employment creation and innovation, and its role in addressing global challenges. Special attention is devoted to the emerging ocean-based industries.
Aquaculture the farming of fish and aquatic plants has become the world's fastest-growing food production sector, even as the amount of wild fish caught in our seas and freshwaters declines. From fish foods and pharmaceuticals to management of entire aquatic ecosystems, acquaculture is truly changing the face of the waters. Increased growth, however, brings increased risk, and aquaculture now lies at a crossroads. One direction points toward the giant strides in productivity, industry concentration, and product diversification. Another direction points toward the dangers of environmental degradation and the marginalization of small fish farmers. Yet another direction invites aquaculture to champion the poor and provide vital environmental services to stressed aquatic environments. 'Changing the Face of the Waters' offers a cutting-edge analysis of the critical challenges facing aquaculture, balancing aquaculture's role in economic growth with the need for sound management of natural resources. The book also provides guidance on sustainable aquaculture by evaluating alternative development pathways, placing particular emphasis on the application of lessons from Asia to Sub-Saharan Africa and Latin America. Aimed at policy makers, planners, and scientists, this book provides a comprehensive frame of reference for orienting ideas and initiatives in this dynamic industry.
