Available in PDF, EPUB and Kindle. Book excerpt: The Olympia oyster is an iconic oyster species in the Pacific Northwest with special significance in Puget Sound, WA. Oyster populations in the region were decimated to historic lows during the 20th century due to a number of factors including overharvest, habitat loss, and invasive species. Restoration projects have seen limited success, likely due to the limited information on stock structure within Puget Sound, especially in regards to adaptive abilities and habitat suitability. Chapter one of this study investigates population related fitness measures (ie. mortality, growth, reproduction) within three resident populations from geographically isolated locations in Puget Sound. Using a reciprocal transplant experiment with Ostrea lurida populations from Fidalgo Bay, Dabob Bay, and Oyster Bay, we found that two of the three populations (Dabob Bay and Oyster Bay) express significant phenotypic signatures related to the population. Using this information we offer restoration strategies catered to population phenotypes in an effort to improve restoration projects in the Puget Sound. In Chapter two, we ran a thermal and mechanical stress experiment due to differences in mortality between populations observed in Chapter 1 to investigate expression of genes (via qPCR) related to survival. We found differences in expression related to gene transcription, which indicates possible phenotypic plasticity previously unknown in the study populations though further investigation is required.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Restoring populations of native Olympia oyster (Ostrea lurida) in the Salish Sea is ecologically and socially valuable. Olympia oysters disperse as planktonic larvae that control their depth with swimming and sinking behaviors, which can affect the currents that carry them and ultimately determine dispersal. Understanding larval dispersal patterns can help prioritize restoration efforts and establish a self-sustaining network of oyster populations in the region. The purpose of this study was to determine which factors (temperature, chlorophyll-a, larval size, current speed, tidal stage) influence the vertical distribution of Olympia oyster larvae in Fidalgo Bay, which is a Washington state priority restoration area. On four consecutive days in July 2017, we collected and analyzed Olympia oyster larvae from four depths over the tidal cycle in combination with temperature and chlorophyll-a measurements. We also measured current velocities profiles in the main channel. Mixed effects modelling results indicate that larvae were distributed significantly shallower when current speeds exceeded ~25 cm s-1 and were deeper when currents were below ~25 cm s-1, but it is unclear whether distribution was due to passive or active larval movement. If larvae were behaviorally controlling their depth, they did not distribute at depth-specific temperature or chlorophyll-a conditions. Larvae did not perform tidally-timed vertical migrations and it remains unclear whether larvae exhibited an ontogenetic vertical migration strategy. Fidalgo Bay does not exhibit a two-way flow or strong vertical shear, so Olympia oyster larval vertical distribution likely has little to no effect on their transport through the main channel of the bay. These results should not be generalized to other restoration areas due to the unique conditions of this location and the possibility of larval behavioral plasticity between distinct populations of Olympia oysters. Results can inform a Fidalgo Bay larval transport model to predict dispersal patterns and prioritize Olympia oyster restoration efforts.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research addresses the effective restoration of Olympia oyster populations in Tomales Bay, Marin County, California. Chapter 2 provides background information on the Tomales Bay estuary, regional history, and ecology of the Olympia oyster. Following this background discussion, each of the three aforementioned degraders of Olympia oyster populations in Tomales Bay is presented: ocean acidification (Chapter 3), sedimentation (Chapter 4), and invasive species (Chapter 5). Each of these issues creates numerous barriers that require the attention of resource protection managers. Chapter 6 presents overall Research Conclusions and Chapter 7 identifies management recommendations to effectively begin the restoration of the Olympia oyster in Tomales Bay. The Olympia oysters of Tomales Bay endured degradation and limitation due to centuries of human activities. Therefore, it is the responsibility of humans to address and manage the degrading factors. As a federally protected estuary, Tomales Bay enjoys certain protections and restrictions against environmentally harmful activities, but violators like ocean acidification, sedimentation, and invasive species cannot be fined or cited. The only solution to their detrimental impacts is for the National Marine Sanctuary Program, its partners and other resource conservation managers to target them at their sources. The Olympia oyster is a native foundation species whose presence improves the water quality and biodiversity of the entire ecosystem. Therefore, Olympia oyster restoration requires immediate consideration, and this document provides those first needed steps towards restoration.

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.
