The charter boats I talk with, and I bank about 10, say that allowing retention of wild silvers will certainly save a lot of fish. Figure 10-25 rods fishing 8 hours on a single boat, releasing as many as 50 fish in a day. Multiply that by 20-30 charter boats on any given day. Multiply that by 120 days. That is a ton of silvers. Also, retaining the silvers lessens the impacts on the wild chinook, as the charters really don't play the catch and release game with wild fish.
