Abstract: | Arteriosclerosis in Oncorhynchur mykiss has been examined histologically in parr, smolts, spawning adults and post-spawning adults captured during downstream migration. All stages of fish from the Clearwater River in Idaho are characterized by the presence of lesions in the main vessel on the bulbus arteriosus. The incidence is lowest in parr, increases significantly in smolts, and is present in 100% of spawning fish. Regression of lesions was not observed in either hatchery or wild fish after spawning. |
