| Impact Description | Prevalence rates of Renibacterium salmoninarum were up to 100% in some parts of the Lake Michigan drainage around 1986. This outbreak of Bacterial kidney disease (BKD) caused heavy mortality in Chinook salmon in 1988 and persisted in the population until 1992. That year, boat fisheries observed at least a 40% decline in Chinook salmon catch per unit effort levels. By 1993, catch per unit effort was 15% of the peak observed in 1986. |
