The Response of Rainbow Trout 'Salmo gairdneri' to 'Aeromonas hydrophila After Sublethal Exposures to PCB and Copper

摘要

Rainbow trout were continuously exposed to sublethal PCB concentrations for 30 days and infected with Aeromonas hydrophila or sham-injected. Mortality of PCB-exposed infected fish was significantly lower than control-infected fish. Survivors of the infection at all exposure concentrations had elevated leucocrits and decreased haematocrits compared with their respective shams. PCB-exposed sham fish had significantly higher leucocrits at both concentrations and significantly lower haematocrits compared with control-shams.
