A system as such would be nice, bit since there isn't just one or two boats tethering, we'd need a number of them, and that takes a lot of money ... we have very limited funds from our own pockets, a grant from the city of Forks, Rayonier Timber, and a few state dollars ... don't see much from any other associations that fish out here (hint). Overall, it doesn't really seem to be too bad on the fish if caution is used (no anchoring afterward in fast water, guide fish downstream through the rock gardens). Unfortunately, the fish that are spawned do die ... so, we do only need a long enough survival to spawn them. The mortality is a little higher than we like, but then again, it's better than going off in a fishbox to be weighed in a club's derby!
