my question is how does this effect spawning fish...for instance salmon river new york...you get thousands of people fishing and losing these magnetic hooks...how does it effect the salmon on the spawn run...i think more research needs to be done before allowing the use of magnetized hooks on rivers and streams...maybe i'm just over cautious...

I did a study years ago. When you put bait under a bobber, you catch anything.

Seems imprudent to add another un-natural attractant to your hook, especially since we have no idea how it will effect a fish if swallowed (it's not lost on me that slamming disguised hooks into a fish's jaw has an impact as well as a fish swallowing a non-magnetized hool)

Fish eat anything flowing downtream given a good drift and a close enough pattern. I can see this working better on stillwater streamers....I can see the process now. Tie the fly, prep the UV-Knot sense, lay the flies under the UV nailbed light, then process them through an electromanetic field to magnetize the hooks......and ya know it, I could see myself doing that. Gimmicky, but I would do it.

Foam is light...magnets are heavy.

Absolutely buckhunter. I am not disagreeing with you on that one. But my observation that a very small percentage of fly anglers are very good at fly fishing is also true. There can be all kinds of reasons for it...the need for immediate gratification today maybe for one. But this thread, and this is a fly fishing thread, is about the worst from the aspect of challenging anglers to get better at flyfishing...I've read Deeter's approach from using worms if you can't get a take, to forget about the need for good casting technique just learn to roll cast it out there, to 3 or 4 Oprah headlines to the use of Tenkara rods to magnets and I didn't even get the magnet thing??...I can guarantee you the good fly anglers I am around, or who I see come into the flyshop wouldn't accept Tankera rods, as a substitute for their traditional flyrods. It would be more just a fun change, and thing to do, than approach it as a more effective way to fly fish. What I think goes on here is that F&S is appealing to a reader group they expect to not be very good at fly fishing, and not even that focused on becoming good fly anglers.

A decent flyfishing blog, or magazine, is not about more fish equals more success. It is about all the interesting aspects about fly angling, from bugs to casting. It is this blog that suggests use a tenkara rod to increase your success when your traditional flyrod doesn't bring success, or use worms when flies do not work to increase your success. I like to encourage the entire fly angling package rather than short circuiting it with gimmickry as a fix.
