Looking at the link Tom (severnfisher) provided on the Fly Size thread got me thinking about the moon, gravity and magnetism. I know there are theories / facts about the ability of the salmon to detect magnetic changes through its lateral lines for the purposes of navigation, but was wondering if anyone has experimented with magnetic flies? Would a magnetically charged tube for example be likely to stimulate an aggressive response in a salmon?? Or would using such a fly confuse the fish causing them to get lost.... Think this could either be a very good idea or a very bad one rather than somewhere in between. Any thoughts or experiences with this? Nolon.

QnQ, Apart from your kind reply I think you will agree that the silence from others is almost deafening, and I can therefore safely assume I have hit on the Salmon-fishing-mother-load. ;D I'm off to investigate ways of applying a magnetic charge to my Willie Gunn; wish me luck! If I fail in my quest I will at least be able to publish a 2008 Calendar 'Sub-surface shopping trolleys of the Tay'. Nolon.

Sounds like an interesting research project owen - tie up some magnetic tubes and let us know how you get on!
Based on what's been said about salmon hotspots been located underneath overhead power lines & above pipelines, perhaps the next must-have accessory from Sportfish will be a portable electro-magnet field generator for salmon fishers!

I think if you were fishing with a copper fishing line and had a high voltage supply available on the bank, then you may have a theoretical means of attracting the fish to the hook, as long as you weren't electrocuted and didn't stun all the fish. But such a method wouldn't be considered sporting and would be banned.
I can't imagine a low level of magnetism, even if the affect is multiplied with a voltage of whatever kind... could ever sufficiently attract a salmon.
Perhaps I am not the best person to comment, I obviously don;t have what the thread title suggests...a "magnetic personality", or at least my magnetism needs its polarity changed.

I thought that the magnetic aspect of this thread was to limited to the hooks (or tubes), and then, having generated such magnetic hooks, tie flies on them, and then use as a controlled experiment - couple be a 'double blind' trial - to see if any difference was noticed between magnetised or non-magnetic (standard) hooked flies, all other conditions being, as far as possible, equal. This could be done by magnetising hooked flies already tied, a bit easier than the tubes. However, not particularly keen to hump an induction coil and a generator to the river bank for the live trial! Mike

Not what I meant at all, are you trying to kill me??? ;D (maybe thats not as dangerous as it sounds but I only passed my O Grade physics to annoy my teacher...) Spent last night between physics chat rooms and tattoo parlours, the former to remind me of the process of magnetizing metal and the latter...well I'll get to that. I need to use a ferrous metal (or 2 types of alloy - the names of which escape me) but basically, iron, cobalt or steel will do. The first one is out as it rusts quickly and though I have yet to look at cobalt I think it is expensive so steel looks likely and as Mike suggests it wouldn't be too hard to magnetize existing hooks. Thinking about tubes I've only seen copper, aluminium and plastic used, probably becuase they dont rust. Does anyone use stainless steel tubes or know where I can get any? The nearest thing I could find was something called a tattooists backtube, on ebay, which was polished steel and looked about the right dimensions. Any suggestions? Oh yes, and in relation to performing any experiment in a controlled environment my first try will be to lower a fridge magnet into the aquarium at home tonight and see if anything happens. It doesnt contain any salmon...but I've got to start somewhere. Agree it would be difficult in a river environment to tell if it made a difference. As I only caught one fish this year, and would have to allow for improvements in my capability which will hopefully continue, perhaps someone who has a more consistent record would be a good person to try this out?? Or if I succeed in catching 2 next year maybe I just patent the concept as a statistically proven sure-fire winner and watch the money stack up?? All suggestions welcome!

Steel tubes.....didn't you ever see the feature on car aerials???

Model making suppliers will have metal tubing available, usually brass, aluminium, copper & plastic, but below is a link to a list of engineering suppliers some of who will make SS tubing to order if they don't stock it. www.modeleng.org/suppliers/supply_m.htmMike

You might try stainless steel hypodermic needle tubing, as shown in the example below: For more information on construction method and component suppliers, see: www.trout-salmon-fishing.com/micro-tubes.htm

That was quick! Just went off and read another thread which gave me some rather nasty deja vous shivvers, came back here, loads of suggestions, and Im in business. Thanks again chaps, will let you know how I get on.....I'm struggling to believe no-one has tried this before though ....you're not all setting me up for some nasty 'when magnets-hit flowing-water' type practical jape I hope... Nolon.

I have tried tying flies on the swagelok tubing and it works well as a substitute for copper. It is stainless steel though, so non-magnetic. Magnetised hooks or Waddington shanks if you require something larger would be the way to go. Saying that I doubt that the magnetic field generated, which will be quite small, will l have any effect on the fish.
