Book excerpt: The Olympia oyster (Ostrea lurida Carpenter, 1864) was designated a species of Special Concern under the Canadian Species at Risk Act in 2003. A management plan was developed in 2009, and a primary objective was maintenance of relative abundance (density) at index sites. Fourteen index sites were chosen to monitor density within their range in Canadian waters. This report summarizes results from 43 surveys at 14 index sites from 2009 to 2017.--Document.

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 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ostrea lurida Carpenter 1864 is the only native oyster on the western North American coast, but it is functionally extinct in most of its historic range. Knowledge of environmental tolerances during larval development of O. lurida is minimal, which limits recovery strategies for this listed "species of special concern" (Species At Risk Act). The effects of rearing temperature (13, 17, 21°C), salinity (11, 15, 21, 24, 30, 31 psu) and food concentration (5x103, 1x104 and 5x104 algal cells/ml) on larval growth and development were investigated. Larvae were obtained from laboratory conditioned adults from Ladysmith Harbour, and the Gorge Waterway on Vancouver Island BC.

Book excerpt: Oyster habitat suitability index (HSI) models can support conservation and restoration planning, siting aquaculture projects, and other purposes. In recent decades, partners have undertaken efforts to restore populations of Olympia oysters (Ostrea lurida) in the Salish Sea. Olympia oyster restoration projects are more likely to become self-sustaining and contribute to overall population growth when sited in locations with optimal conditions. This study describes the development and application of a preliminary HSI model for Olympia oyster restoration in the southern Salish Sea. Environmental data and tolerance thresholds for six habitat variables – tidal elevation, salinity, temperature, current velocities, low salinity events, and water residence time – are compiled to create a geospatial index of suitability. This study identifies potentially suitable habitat throughout the study region. HSI output is compared to oyster observations and abundance at restored sites to evaluate accuracy and consider potential applications. While predictions of suitable habitat and oyster presence and abundance align in some locations, there are limitations to using the index as a tool for restoration planning. In addition, this study provides an example of how the HSI may be used to explore climate change considerations for restoration projects. The results of this study, in combination with other methods and information, may provide a useful preliminary tool for identifying potentially suitable locations for Olympia oyster restoration projects in the region.

This book was released on 2018 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Olympia oysters (Ostrea lurida), a species of concern in Washington State, have failed to fully recover after both overexploitation and environmental degradation. State agencies, tribal nations, and environmental groups in Washington have made it a priority to restore O. lurida because they are the only native oyster on the west coast of North America and provide key habitat and ecosystem services to the Puget Sound. Despite this interest, our understanding of O. lurida larval dispersal patterns remains limited. The early life stage of Olympia oysters play a key role in their restoration because it is the only time when they can disperse to other populations. While being brooded, Olympia oyster larvae incorporate trace elements present in estuarine waters into their shell, creating a chemical “signature” of their natal site before release and dispersal providing a way to track their larval connectivity patterns. However, collecting brooded larvae from a species undergoing restoration efforts poses procedural challenges because it traditionally requires sacrificing significant numbers of adults to find enough reproductive females. The first objective of this study, therefore, was to develop a non-lethal sampling approach to collect brooded larvae. Exposure to magnesium sulfate (MgSO4) was assessed in lab trials as an anesthetization method to allow for the non-lethal collection of brooded Olympia oyster larvae. In the field, over 14,000 oysters were then anesthetized to assess reproductive status and validate the procedure. The anesthetization method of 45 min air exposure followed by 45 min submersion in 100 g/L MgSO4 was found to have a success rate > 80% in the field. This anesthesia method for O. lurida allows for non-lethal sampling of assessing reproductive status and collection of brooding larvae, as well as for obtaining tissues for genetic analysis, biopsy for diseases. The second objective of this work was to determine the viability of elemental fingerprinting for tracking larval dispersal patterns of O. lurida. With the use of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), the provenance signatures of larvae and recruits can be compared, and potentially matched, to signatures of source populations. Unique elemental fingerprints of O. lurida larval shells were found in three regions in Puget Sound. This provides an approach to quantifying larval dispersal that can be used to determine the extent to which these O. lurida populations self-seed, seed other sites, and exchange larvae with other populations.
