This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fouling organisms associated with suspended oyster aquaculture can significantly increase operational costs for growers and significantly decrease product marketability. Currently, there is little information available on the fouling communities present on deep-water, suspended tray Pacific oysters (Crassostrea gigas). In general, the industry practice in tray production of Pacific oyster is to use plastic trays, but a new polyvinyl-coated metal tray, which accommodates higher oyster densities, has recently become available. The objectives of this thesis were firstly, to assess whether differences exist in the extent of tray fouling between the 2 tray types using abundance, species richness, biomass, and dominance (univariate analyses) and the Bray-Curtis Dissimilarity Coefficient (multivariate, cluster analysis) as measures (Chapter 2) and secondly, to describe variation in the fouling organisms present on the oysters in the 2 tray types using the same univariate and multivariate analyses (Chapter 3). This study took place on a commercial oyster farm between the months of October 2006 and October 2007. Overall, there was little difference in the extent of fouling communities between the tray types, although a few species were present on plastic trays only, but in very low abundance. The fouling communities associated with the trays and oysters were studied in the winter, spring, summer (tray only) and fall to determine seasonal variation in the fouling communities. Abundance, species richness, biomass and dominance in the tray fouling communities were affected by season with the greatest values in July and the lowest values in January. Season also influenced the oyster fouling communities. Abundance, biomass and dominance of the fouling communities on the oysters was higher in October, while species richness was lowest in January compared to April or October. The seasonal changes observed in the fouling communities on both the trays and oysters were driven largely.

Download or read book Nonnative Oysters in the Chesapeake Bay written by National Research Council and published by National Academies Press. This book was released on 2004-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.
Download or read book Ecosystem Concepts for Sustainable Bivalve Mariculture written by National Research Council and published by National Academies Press. 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.
