Over the years ive heard quite a lot of people say that the fishing is good when air pressure is rising and not so good when air pressure is falling. I personally have cought fish in both rising and falling air pressure and havent noticed any difference I cought one of my biggest Trout when the air pressure had fallen over 20mb in 30 hours. Anyone else got had any experance of air pressure affecting fishing?
I think a steady or rising barometre will give you the best fishing especially if they have to chase or find what you are offering
but a Trout sitting behind a rock will take a nymph going past anytime. The hardest time to catch fish for me is the week after the full moon thats when ill go and shoot something instead.
