Salmonella is a genus of Gram-negative bacteria that is responsible for numerous food poisoning outbreaks worldwide. With 93.8 million food-borne illnesses and 155,000 fatalities annually, it has emerged as a significant global public health issue. There are currently more than 2,500 distinct Salmonella serotypes, and more than half of them are associated with Salmonella enterica. An increasing global public health concern for humans and animals is antimicrobial resistance by Salmonella species worldwide. Salmonella infections can be lethal; conditioned with an increased prevalence of multi-drug resistant (MDR) strains in the future. The emergence of MDR Salmonella serotypes is considerably …

Maine Policy Review
Coastal marine ecosystems are dynamic social-ecological systems (SESs) that support diverse ecosystem services and human activities. The complexity of SESs means that ecosystem-based approaches are increasingly used to support coastal marine ecosystem stewardship. We report how a community science program in Maine, USA offers a model of organizational innovation to expand capacities for shellfish research and management. Since 2019, we have collaborated with local students, shellfish harvesters, and others in data collection, interpretation, and application, contributing to local shellfish management and ecosystem sustainability. We demonstrate how community-based social and ecological research can build adaptive capacities by centering local knowledge; generating …

Impact Of Septic Systems In Drayton Harbor Water Quality, Jennifer Hayden
Salish Sea Ecosystem Conference
Septic systems are personal wastewater treatment systems for rural properties. Over 3,000 septic systems exist in the Drayton Harbor watershed. Septic systems that are not maintained properly can create problems for homeowners, negatively impact water quality, and pose a public health threat. Whatcom County Health Department (WCHD) began implementing a septic system operation and maintenance (O&M) program in 2008 in the Drayton Harbor watershed when most of Drayton Harbor was classified as Prohibited for shellfish harvesting due to elevated fecal coliform bacteria levels. The local health officer’s designation of Drayton Harbor as a Marine Recovery Area in 2008 allowed WCHD …

The intensively trained partners provide early warning of harmful algal bloom (HAB) events by evaluating water samples gathered weekly from 35 stations throughout Puget Sound looking specifically for Dinophysis, Alexandrium, Pseudo-nitschia and Azadinium and alerting health and natural resource agencies of their presence and concentration. The online database and mapping allows for near-real time viewing of data entered by SoundToxins partners …
Dye And Microbial Study In Response To Outbreak Of Norovirus-Like Illnesses From Consumption Of Shellfish From Hammersley Inlet, Washington, Mark Toy
Salish Sea Ecosystem Conference
The Hammersley Inlet Growing Area has experienced several clusters of norovirus-like illness in recent years. This presentation will describe a recent study to help evaluate how likely the Shelton WWTP is a potential source of viral loading to the growing area. A hydrographic dye study of the WWTP effluent was conducted by injecting dye at the WWTP at a continuous rate over a full tidal cycle (approximately 24 hours) to approximate steady state concentrations. Sampling of wastewater was also done to evaluate microbial removal across the treatment train. Sentinel shellfish cages are also deployed to measure bioaccumulation of microbial indicators. …

Salish Sea Ecosystem Conference
Climate change is a pressing environmental concern, and understanding how abiotic variation contributes to population dynamics and persistence may ultimately predict the fates of species. Ocean acidification negatively impacts a range of species, including those using calcium carbonate for shell formation such as shellfish, which are important as ecosystem engineers and for food security. While much is known about carbonate chemistry and impacts of ocean acidification on the U.S. Pacific coast, there is limited regional information in British Columbia (BC), especially in socio-economically important coastal zones for aquaculture and migrating fisheries populations. Laboratory experimentation mimicking future climate scenarios provide valuable …

Shared Waters: Restoring Shellfish Harvest In The Trans-Boundary Watershed Of Boundary Bay, Christy Juteau
Salish Sea Ecosystem Conference
Boundary Bay is a critical section of transboundary Salish Sea habitat, recognized locally, nationally and internationally. The intertidal salt marshes, mudflats and open water marine habitats of Boundary Bay comprise Canada’s top rated, globally significant, Important Bird Area (IBA Canada 2017), have recently been named a “Wetland of International Importance” as part of the Fraser River Delta Ramsar site (Ramsar 2012) and are “protected” through BC’s Wildlife Management Area designation (MFLNRO 1995). Indigenous peoples (including Semiahmoo First Nation) traditionally harvested the abundant fish and shellfish resources for their livelihood. Commercial oyster operations in B.C. began in Boundary Bay in 1904 …

Social And Economic Impacts Of A 2017 Oyster-Transmitted Norovirus Outbreak In Hammersley Inlet, Puget Sound, Marisa Nixon
Salish Sea Ecosystem Conference
Hammersley Inlet in Washington State is a highly productive growing area for oysters, with at least 34 different commercial shellfish growers operating in its tidelands. The oysters in Hammersley Inlet provide an important source of income, employment and recreation for surrounding Mason County. In early spring 2017, Hammersley Inlet was implicated in a shellfish-transmitted norovirus outbreak that resulted in growing area closures and recalls, significantly impacting small, local shellfish farmers. From its initial illness investigation, Washington State Department of Health (DOH) was unable to identify a point pollution source responsible for the outbreak, and some shellfish producing parcels remained closed …

In many areas, coastal residents and others oppose establishment of bivalve molluscan aquaculture projects on the basis of perceived negative environmental impacts. Often overlooked are positive environmental impacts of shellfish aquaculture that can potentially mitigate the impacts of other anthropogenic activities. Filter feeding by populations of bivalve mollusks is reviewed with respect to their ability to act as an estuarine filter, increase clarity of coastal waters and facilitate the removal of nitrogen and other nutrients from eutrophic coastal waters. Most species of cultured bivalve mollusks clear particles from waters at rates of 1 to 4 L/h, and populations of shellfish …

Price Flexibility Analysis Of Virginia Hard Clams: Economic Considerations For Management Of The Fishery, Andre C. Kvaternik, William D. Dupaul, Thomas J. Murray
Reports
Price flexibility coefficients estimated for ex-vessel prices of Virginia hard clams indicate a very small (4.292 x 10-6 to 6.994 x 10-6%) decrease in price would occur given a 1% increase in the quantity supplied by Virginia harvesters. Data used were monthly landings of Virginia, New York, New Jersey, Rhode Island, Maryland and North Carolina over the period 1960-1979. Fifty-eight percent of the ex-vessel price changes are not explained by the supply response model used, suggesting other market and consumer demand factors play a large role in determining ex-vessel price. This conclusion is reached considering the historical range of production …
