| Notes | “Low temperature disease (LTD) is an acute septicemic infection of young coho salmon (Oncorhynchus kisutch) caused by the myxobacterium Cytophaga psychrophila (Borg). Fish infected with this bacterium usually develop an open lesion or dark discoloration in their peduncle region. . . C. psychrophila has been found to be responsible for severe losses in coho and other sairnonids at fish hatcheries throughout the Pacific Northwest.” (from the Abstract) This study isolated and compared different strains of C. psychrophila from different Oregon hatcheries. A possible treatment was tested at the Siletz River Salmon Hatchery, “which experiences an annual predictable LTD epizootic in their fingerling coho.” (p.53) Major professor was John L. Fryer. |
