Description

Abstract: Bacterial kidney disease (BKD) is a major health problem of cultured Pacific salmon, Oncorhynchus sp. It has been particularly problematic in captive broodstock programs, where the interests of gene conservation and fish health can conflict when spawning females with signs of BKD. Not rearing those fish reduces the genetic diversity of an already depleted population, while rearing those fish may increase the prevalence of BKD in the natural population. We used data collected during spawning at Lookingglass Fish hatchery and on spawning ground surveys to examine the prevalence of BKD, based on enzyme-linked immunosorbent assay optical density (ELISA OD) values, to monitor the prevalence of BKD in natural and hatchery-reared Chinook salmon O. tshawytscha from Grande Ronde and Imnaha basin streams in northeast Oregon.
