Shellfish Under Siege: Parasites and their Impact on New England Aquaculture
Shellfish aquaculture is a vital component of New England's blue economy, contributing nearly $50 million annually in dockside value. However, this industry faces mounting challenges from climate change and diseases, which often interact synergistically to amplify their impacts. Over the past five years, the Davinack Lab has investigated the life history, ecology, and evolution of macrofaunal parasites infecting natural and commercially reared shellfish across New England, including bay scallops on Nantucket Island, oysters on Cape Cod, and mussels in Maine. This presentation highlights new findings on the vulnerability of these shellfish populations, including the effects of mud-blister disease caused by shell-boring polychaetes on Eastern oysters (Crassostrea virginica) and the population connectivity of the trematode flatworm Proctoeces maculatus, which infects the mantle tissue of Blue mussels (Mytilus edulis). Our results reveal troubling trends, including increased parasite loads and genetic homogenization, likely driven by the intraregional and transnational movement of hosts and range expansions linked to rising ocean temperatures.
