October 10, 2019 — Several scientists at the University of Rhode Island have been awarded grants to study oyster genetics, breeding and diseases as part of a region-wide effort to support the growing oyster aquaculture industry in the Northeast and assist efforts to restore wild oyster populations.
“Wild and farmed oysters are facing major threats from water quality and disease,” said Marta Gomez-Chiarri, a URI professor of animal science who has studied oyster diseases in Narragansett Bay for more than 20 years. “Even though local water quality has improved in Rhode Island, oysters across the United States face localized threats from pollution and eutrophication while at the same time dealing with multiple factors of global ocean change, like ocean acidification, as well as changes in salinity and dissolved oxygen. We are only beginning to understand the effects of these multiple stressors.”
Gomez-Chiarri — along with URI Assistant Professor Jonathan Puritz and U.S. Department of Agriculture scientist Dina Proestou — have teamed with shellfish geneticists and breeders from 10 other East Coast universities to form the Eastern Oyster Genome Consortium to develop genetic tools to accelerate selective breeding efforts. The consortium, in a proposal led by Rutgers University, has been awarded a $4.4 million grant from the Atlantic States Marine Fisheries Commission to accelerate the pace of identifying the genes responsible for desirable traits like disease resistance.
