decreased mortality of lake michigan chinook salmon after bacterial kidney disease challenge: evidence for pathogen-driven selection?in the late 1960s, chinook salmon oncorhynchus tshawytscha from the green river, washington, were successfully introduced into lake michigan. during spring from 1988 to 1992, large fish die-offs affecting chinook salmon occurred in the lake. multiple ecological factors probably contributed to the severity of the fish kills, but the only disease agent found regularly was renibacterium salmoninarum, the causative agent of bacterial kidney disease. in this study, survival after challenge by r. salm ...200819306612
genetic variation in bacterial kidney disease (bkd) susceptibility in lake michigan chinook salmon and its progenitor population from the puget sound.mass mortality events in wild fish due to infectious diseases are troubling, especially given the potential for long-term, population-level consequences. evolutionary theory predicts that populations with sufficient genetic variation will adapt in response to pathogen pressure. chinook salmon oncorhynchus tshawytscha were introduced into lake michigan in the late 1960s from a washington state hatchery population. in the late 1980s, collapse of the forage base and nutritional stress in lake michi ...201424689954
