Flavobacterium psychrophilum Infections in Salmonid Broodstock and Hatchery‐Propagated Stocks of the Great Lakes Basin
Abstract Bacterial coldwater disease (BCWD), caused by Flavobacterium psychrophilum , threatens wild and propagated salmonids worldwide and leads to substantial economic losses. In addition to being horizontally transmitted, F. psychrophilum can be passed from infected parents to their progeny, furt...
