Book Description
U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.

Book Description
The aim of this open access book is to review and analyse the goods and services of bivalve shellfish. How they are defined, what determines the ecological functions that are the basis for the goods and services, what controversies in the use of goods and services exist, and what is needed for sustainable exploitation of bivalves from the perspective of the various stakeholders. The book is focused on the goods and services, and not on impacts of shellfish aquaculture on the benthic environment, or on threats like biotoxins; neither is it a shellfish culture handbook although it can be used in evaluating shellfish culture. The reviews and analysis are based on case studies that exemplify the concept, and show the strengths and weaknesses of the current applications. The multi-authored reviews cover ecological, economic and social aspects of bivalve goods and services. The book provides new insights for scientists, students, shellfish producers, policy advisors, nature conservationists and decision makers. This book is open access under the CC BY license.

Book Description
Shellfish Aquaculture and the Environment focuses primarily on the issues surrounding environmental sustainability of shellfish aquaculture. The chapters in this book provide readers with the most current data available on topics such as resource enhancement and habitat restoration. Shellfish Aquaculture and the Environment is also an invaluable resource for those looking to develop and implement environmental best management practices. Edited one of the world's leading shellfish researchers and with contributions from around the world, Shellfish Aquaculture and the Environment is the definitive source of information for this increasingly important topic.

Book Description
ÿFish?including finfish and shellfish?are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world?s fish consumption occurs. In addition to protein, fish contain micronutrients and longchain omega-3 fatty acids that are essential for maternal and child health, but often deficient in the diets of the poor. However, the global supply of wild-caught fish has long peaked and is unlikely to rise again unless overexploited stocks are rehabilitated. As world fish consumption continues to grow, aquaculture (fish farming) has emerged to meet demand. Already, just under half of all fish that people consume come from aquaculture, which is one of the world?s fastest-growing animal food producing sectors. With the supply of wild-caught fish stagnant, any future increase in world fish consumption will need to be supplied by aquaculture. This working paper explores the potential role of aquaculture in meeting global fish demand in 2050, finding that aquaculture production will need to more than double by midcentury. The authors examine scenarios of aquaculture?s growth and environmental impacts in 2050 and close with a series of recommendations for how to sustainably grow aquaculture production.

Book Description
This book presents a solutions based approach to reducing and removing CO2 from the atmosphere transforming it into solid (crystalline) CaCO3 through the ability of marine organisms such as molluscs, crustacea, corals, and coccolithophore algae. The overwhelming advantage of this approach is that it promises enhanced climate mitigation in comparison to planting forests, industrial/engineering carbon capture and storage process. It also provides a sustainable food resource. Furthermore, it would improve the ocean's biodiversity at the same time as the excess atmospheric CO2 released by our use of fossil fuels is returned to the place it belongs - as a present day fossil, safely out of the atmosphere to the distant future. If the level of finance and global effort that are readily foreseen for forest management and flue gas treatments were applied to expansion of global shellfish cultivation, curative amounts of carbon dioxide could be permanently removed from the atmosphere within a few decades. The concept presented in this book could have a profound influence on the life of the planet.

Book Description
The Global Conference on Aquaculture 2010 brought together a wide range of experts and important stakeholders and reviewed the present status and trends in aquaculture development, evaluated the progress made in the implementation of the 2000 Bangkok Declaration and Strategy, addressed emerging issues relevant to aquaculture development, assessed opportunities and challenges for future aquaculture development and built consensus on advancing aquaculture as a global, sustainable and competitive food production sector. This volume, yet another joint effort of FAO and NACA, brings the outcome of the Global Conference on Aquaculture 2010, the much-needed clear and comprehensive technical information on how aquaculture could be mobilized to alleviate global poverty and improve food and nutrition security in the coming decades.

Book Description
Exploring the potential use of bivalves as indicators and monitors of ecosystem health, this book describes live and computer simulated experiments, mesocosm studies, and field manipulation experiments. This second edition discusses major new developments, including phase shifts in many coastal and estuarine ecosystems dominated by suspension-feeding bivalves, the invasion or introduction of alien bivalve species, the rapid growth of environmental restoration focused on bivalves, and the examination of geological history with regard to global climate change and its impact on bivalve-dominated systems.
