Steelhead trout were exposed to sublethal concentrations of copper and inoculated with Yersinia ruckeri. Copper exposure at 7 and 10 micrograms/1 for 96 h caused more fish to die of infection than control fish (no copper). Infection susceptibility increased with time of exposure to a single dosage of copper (10 micrograms/1), reaching a maximum at 48 h. Lowering the copper concentration to 5 micrograms/1 caused the infection susceptibility to occur at 24 h. The infectious dose of Y. ruckeri was lower in fish exposed to 10 micrograms/1 copper for 48 h than control fish.
