A total of 13 rockfishes was examined for the presence of monogenetic trematodes, and 46.2% of thirteen fish were infected. Two parasites were recovered from the gills of canary rockfish, Sebastes pinniger and darkblotched rockfish, Sebastes crameri in the Oregon Coast Aquarium and newport fish market. These parasites included Trochopus trituba, and Trochopus australis. Specimens of T. trituba were recovered from the gills of S. pinniger, while T. australis were found on the gills of S. crameri. In monogenetic trematodes, prevalence and mean intensity ranged from 40.0% and 2.3 in T. australis to 66.7% and 55.0 in T. trituba. Prevalence and intensity in S. pinniger were 15.4% and 18.3, respectively, and for S. crameri they wee 30.8% and 1.5 respectively.
