The comparative susceptibility of naive Atlantic Salmo salar, chinook Oncorhynchus tshawytscha and coho Oncorhynchus kisutch salmon to infection wlth the economically important marine ectoparasltic copepod Lepeophtheirus salmonis was investigated under laboratory conditions. Coho salmon were the most resistant to infection followed by chinook then Atlantic salmon. Copepods were lost from the gills of coho salmon by 10 d post-infection and only a few remained on the fins at 20 d post-infection Although thelr abundance declined significantly, copepods were retained on both the gills and fins of chinook and Atlantic salmon over the 20 d studied. Rejection of L. salrnonis on all 3 host species appears to be due to non-specific host responses. Histological sectlons of coho fins and gills revealed well-developed epithelia1 hyperplasias and inflammatory responses to the presence of L. salmonis. Gill and fin tissue responses of chinook salmon to L. salmonis appeared to be intermediate in intensity between those of coho and Atlantic salmon. Only minor gill and fin tissue response to the presence of L. salmonis was observed in Atlantic salmon.
