A friend of mine caught a very ripe Atlantic hen in the Sultan R. in September '97, also on a spinner. Looks like the Sky system is popular with these fish. I got pictures of the fish -- not that anyone would doubt they're there after so many "sightings!"
Another friend, a fish biologist, says they'll never become established here because there have been official attempts to get them going here, with no luck. But that happened in the Great Lakes with Pacific salmon introductions for most of the 60's and all of a sudden, the kings, coho and steelhead got established big time.
