The second half of august through september in Ketchikan is the peak of the best silver fall silver fishing in Alaska. The silvers (coho) salmon in September are some of the biggest in the world with lots of fish over the 15 pound mark and a handful a year pushing 20 pounds. They are hard fighting acrobatic fish. The halibut fishing is also still great this time of year. If you’re looking for big hard fighting silvers august and September is the time to come fishing in Ketchikan Alaska!
