On our Invery week on the Dee earlier in the month, a well known fishing personality appeared on the Sunday night in the bar with Mr Bett's book and a Casio Barometric watch.
That night after a few beers we were taking the p--s out of said gentleman. By the end of the week we were all buying the watch. The theory about rising barometric pressure works and was confirmed by the timing of our catches.

I heard the other week of a middle Tweed Ghillie (Boatman?) who had spent most of his working life on the river. He looked back through his records to see if he could establish any pattern of fish taking behaviour.The only pattern he could detect (all others things being equal of course e.g time of year, height of water etc) was that most of the fish were taken on a steady or rising pressure of 970 millibars and over.
Not conclusive of course but it does give food for thought.

Well
I have one of those weather stations and I thought I was on to something as well.
I kept a note of the pressure and it always seemed to be about 1020 m bars. When I caught fish. I must admit that I did not catch every time it was this but then as the season got later it did not make any difference - water colour and height became more crucial. --- The theory got booted.
I think depth is far more important. Fish your fly at the right depth and you stand a better chance.

Last year in Norway was the confirmation I needed. We arrived at the end of week 28 (mid-july) and the weather was good and air pressure high. Fish were being seen and caught that week. We started fishing on week 29 and the pressure started to fall. It fell steadily all week with the exception of a few bilps here and there. Our catches were poor and very few fish seen (in comparison to other years). We had many plucks and pulls but only a few fish landed. Of these few, most were taken during these blips when there was a small rise in pressure. It was quite predictable. 1mb of rise could envoke a take.
I have one of these watches and wear it everytime I go fishing, but up and till Norway last year I've never seen how greatly pressure can affect fish behaviour. I don't believe in going all scientific when salmon fishing, but air pressure more than anything can make fish take or not.
Might not take my watch this year....((-:
