Book excerpt: Mollusca is one of the largest phyla in the animal kingdom, over 50,000 species having been described, thus comprising more than a half of the marine species. Molluscs are scientifically and economically important invertebrates, representing 8% of all captured marine species. One of the six molluscan classes is Bivalvia, which is composed of both marine and freshwater animals enclosed in shells with two valves. Among these, the groups of greatest economic importance are oysters, scallops, mussels and clams. This book deals with clams in the broad sense of the term, since there are several bivalve families falling into the "clam" category. The selection of the families is primarily based on their respective economic importance, in terms of fisheries and aquaculture production. These selected families are Veneridae (venus shells), Mactridae (surf clams), Donacidae (wedge shells), Myidae (softshell clams), Pharidae and Solenidae (razor clams). It must be remarked that, in some chapters or sections within them, species belonging to other families of clams are cited.

Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Clams have been harvested along the coasts of North America for as long as records have been kept. They support commercial, sport and subsistence fisheries although unfortunately, with few exceptions, the harvest of these invertebrates is declining. This decline is probably caused by a number of factors including pollution and overfishing. In an effort to ameliorate this situation, interest in the aquaculture of these species has grown.Intensive semi-controlled clam culture has been attempted in North America for almost three decades. However, it was not until the last decade that a number of entrepreneurs actually began clam farming and developing successful and profitable operations. This success has been possible because of numerous scientific and practical contributions made by a great number of scientists, growers, and clammers over the years, and by a healthy market demand caused by a downward trend in the wild harvest.Many of the

This book was released on 2010-03-18 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
