Chris Langdon has been conducting aquaculture research with COMES for over three decades, and his innovative work has been instrumental in supporting the research needs of the aquaculture industry. Current shellfish research involves selecting oysters for greater resistance to ocean acidification, oyster diseases, and summer mortality stress. Probiotic treatments are being developed to control bacterial diseases.  Chris’s research program also focuses on bivalve and finfish larval nutrition using microencapsulated nutrients, as well as the impacts of microplastics on bivalve larvae.

Chris' research involving the sea vegetable dulse, a nutrient-rich, red marine algae, has been widely publicized due to dulse's reported bacon-like flavor when deep-fried. Dulse grows very quickly in land-based aquaculture systems and contains 20% protein by dry weight, which means that it could be part of the solution to feeding our rapidly increasing global population with more limited freshwater supplies.

In preparation for Chris’ upcoming retirement, his pioneering Molluscan Broodstock Program (MBP) is transitioning to USDA-ARS’ Pacific Shellfish Breeding Program (PSBC) in 2022. You can read more about MBP and the PSBC here.
