Includes bibliographical references (pages 12-13). "Complete necropsies were performed on 40 yellowtail rockfish, Sebastes flavidus. Twenty specimens were taken from a sample captured off Cape Scott, British Columbia and 20 were from a sample collected near Destruction Island, Washington State. The principal objective of the study was to identify which parasites show potential as biological tags for the purpose of stock identification. Secondary objectives included outlining a general necropsy procedure and creation of a reference collection of identified parasites for future studies of this fish species. Prevalence and intensity rates are summarized. Twenty different parasites were recorded in this survey, several of which appear to show promise as biological tags. These include the monogenean, Microcotyle sebastis and a species of Copepoda, Neobrachiella robusta, both of which occupy the opercular cavity; Chondracanthus triventricosus, a species of copepoda which is found in the nasal cavity; and four species of Digenea from the digestive tract; Derogenes varicus, Plagioporus sp., Lecithochirium exodicum and Podocotyle sp. In addition, M. sebastis, Myxidium japonicum, Myxidium sp., Leptotheca sp. and Pleistophora sp. are recorded from S. flavidus for the first time"--Abstract, page iii.
