Captive Broodstock Pathology data (Infectious disease diagnostics for ESA-listed captive broodstock salmon)

The abundance of Snake River sockeye salmon has been severely impacted by the construction of dams on the Columbia River and other environmental factors. The only remaining sockeye salmon in the Snake River system are found in Redfish Lake in Idaho, and the number of returning salmon each year is so low that despite attempts to improve fish passage through the Columbia River Power System, the risk of extinction remains a strong possibility.

Consequently, sockeye salmon are being held in a captive broodstock program at the NMFS/Northwest Fisheries Science Center Burley Creek hatchery and Manchester Research Station. Shortly after spawning in the fall, eyed eggs from these broodstock are transported back to Idaho. Transport of live fish requires permits from both the states of Idaho and Washington and in order to obtain transport permits, pathology reports must be completed to assure state agencies that infectious diseases are not transferred with the fish. Raw and summarized data on fish pathology performed on mortalities in NWFSC ESA-listed captive broodstock program. Data includes fish identification and physical data, PIT tag numbers, and results of pathology/infectious disease tests. Data maintained in Filemaker Pro database
