Friedman, Carolyn, Principal Investigator
OA Exposure Effects on Pacific Oysters
Washington Sea Grant research documented the effects on performance of later-life and transgenerational Pacific oysters due to early exposure to acidified waters, and assessed genetic factors for breeding acidification-tolerant lines.
Friedman, Carolyn, Principal Investigator
Ocean Acidification Effects on Calcifers
Examining five ecologically and economically important bivalves, researchers found these species exhibit different susceptibility to increasing CO2 levels. Under the conditions tested, clams were relative winners and oysters losers.
Friedman, Carolyn, Principal Investigator
Tools to Fight Bivalve Viruses
Researchers developed early detection and diagnostic tools for emerging bivalve aquaculture diseases to improve emergency preparedness, rapid response and regulatory decision-making.
Friedman, Carolyn, Principal Investigator
Researchers assessed whether native eelgrass and Pacific oysters can synergistically enhance their environments.
Gallagher, Evan, Principal Investigator
Ocean Acidification and Salmon
This study clarified the mechanisms that underlie loss of smell in coho salmon and determines the effects of increased waterborne CO2 on olfactory and navigational functions, both of which are crucial to salmons’ ability to find their way back to their home streams to spawn.
Greengrove, Cheryl, Principal Investigator
Studies revealed that surface-sediment cyst mapping alone may not reveal the full risk of Alexandrium catenella blooms. Determining the share of cysts capable of germinating helps shellfish growers anticipate toxic blooms.
Grünbaum, Daniel, Principal Investigator
Low-Cost Sensor Network for HABS
This project deployed a new imager network to collect and disseminate continuous, broad-scale data on harmful algal blooms to improve detection, monitoring, and mitigation processes.
Grünbaum, Daniel, Principal Investigator
Optical Tools for HAB Detection
Researchers created new imaging technology for monitoring harmful Alexandrium and Heterosigma algae, and developed a new model for predicting when and where Heterosigma will form HABs.
Hauser, Lorenz, Principal Investigator
Guidelines for Rock Scallop Aquaculture
Researchers used several experimental approaches to investigate rock scallop populations’ genetic differentiation, habitat adaptation, and resilience to acidification.
Hauser, Lorenz, Principal Investigator
Managing Genetic Risks of Native Shellfish Aquaculture
Researchers addressed genetic risks of native shellfish aquaculture by developing genetic risk assessment tools and evaluating risk management strategies.
Hudson, Bobbi, Principal Investigator
Biotoxins Uptake in Rock Scallops
Investigators examined rock scallops to help establish an approved, reliable assay for evaluating biotoxins and to improve growout methods for the purple hinged rock scallop.
Hudson, Bobbi, Principal Investigator
Planning Shellfish Aquaculture
This research combined geospatial data and an examination of the social dimensions of shellfish aquaculture to ensure that it is fully integrated into coastal and marine spatial planning along the U.S. West Coast.
McDonald, P. Sean, Principal Investigator
Climate Change Impacts on Dungeness Crab
Scientists examined the effects of changing water temperature on Dungeness crab, Washington’s most valuable harvest, and developed bioenergetic models to guide management strategies.
