I'd reserve judgment Curt. I've asked some biologists who specialize in this area for their input. Joe Jacquet for instance published a body of work several years ago sampling the stomach contents of sea run cutthroat in the south sound throughout the calendar year in various locations. In recent years when the resident Coho population was especially abundant, we took a lot of them home, and were very surprised to find them choked with herring in the 5-6 inch size. According to my recollection of Joe's work, these herring are not a major component of cutthroat fare. Also, unlike cutthroat which are true residents Coho leave the area when food is scarce migrating north until until they find adequate forage, and have been observed in the Straits of Juan De Fuca. Cutties don't do that. Again, like Roger, this is my personal observation based on a small and informal sampling size. I am going to ask Joe and a couple of other professionals I know for their input on this subject, as they is more sophisticated on forage habits of both species than sport fishermen who are not authorized to pump the gullets of src's.
