If Puget Sound coho were to be listed I suspect it would be similar to Puget Sound chinook. The Puget sound chinook esu includes all naturally spawning chinook in rivers and streams flowing into Puget Sound and the straits of Juan De Fuca east of the Elwha River. It also includes 26 artificial propagation programs (hatcheries). Listing individual bodies of water in the coho petition is more of a statement about habitat than harvest or hatcheries. Like chinook I suspect it impossible to find any distinct genetic or phenotype differences among the naturally spawning coho and hatchery coho in Puget Sound so the esu would include hatcheries. If coho were listed the fishery would probably be similar to the present chinook fishery. Mixed stock fisheries would be MSF and there would be freshwater and terminal area fisheries where any coho could be retained.
