The effects of single and repeat Lepeophtheirus salmonis (sea lice) infections on the health of juvenile Pacific salmon

PARR-2010-P-01

Description

There is evidence that different species of Pacific salmon differ in their susceptibility to infections with the sea louse, Lepeophtheirus salmonis, under laboratory conditions. For example, pink and coho salmon have been shown to be less susceptible to sea lice infections than chinook or chum salmon. This multi-year project is examining the susceptibility and lethal infection level of juvenile sockeye, coho, and chum salmon to L. salmonis. In addition, the effects of previous exposure to L. salmonis on susceptibility to infection and the physiological and immunological responses will be determined for these species.
