Augmented Fish Health Monitoring in Idaho, 1990-1991 Annual Report.
The Idaho augmented fish health monitoring contract DE-A179-87BP65903 was awarded in June 1987 and fully implemented in January 1988. The fourth annual report of activities serviced under this contract is presented. The prevailing fish health problems in 1990 include persistent infections caused by Mvxobolus cerebralis and Flexibacter osvchronhilus. Subclinical infections of Renibacterium salmoninarum have been confirmed in pools of chinook kidney tissues using Enzyme-linked immunosorbant assay (ELISA), but to date, mortality and clinical signs were not apparent in juvenile anadromous fish. Clinical signs were observed in returning brood chinook at all chinook facilities. Furunculosis (Aeromonas salmonicida) was isolated in conjunction with mortality at Niagara Springs in the spring of 1991. The anadromous fish pathologist position was accepted by Doug Munson in July 1991. Complete diagnostic and inspection services were provided to eleven Idaho anadromous facilities. This report describes work done to meet contract agreements and summarizes the fish health findings of anadromous stocks reared at and returning to Idaho's facilities during 1990-1991.
