The Nisqually has Winter Chum, the latest run in the Sound. They really don't even show up in-Sound until early December. They are also, at least anecdotally, larger than the run of the mill Summer or Fall fish. One of my former bosses, while sampling fish at a buyer's, saw two Nisqually fish that were 56 pounds for the pair.

Probably larger due to more ocean time. Glad that they are back to reasonable abundance levels. Back in my day they were a very valuable commercial and sport species.
