Hi all
I think this is right? some bloke was on about this on sunday while i was fishing, could someone explain Barometric Pressure to me please about the was it affects the fish feeding or something like that as the bloke talking to me was scottish and couldnt understand most of the time.


cheers mitch

Hi

Basically anglers believe Trout and Salmon are affected by air pressure (Barometric Pressure). They feed more consistently/confidently when the air pressure is on the increase, like just before a rain storm, approaching evening time or when high weather fronts are moving in.

There is a book called The Barometric Breakthrough by Andrew Bett which is a study over seven years detailing when he caught Salmon and how it corresponded with the air pressure at the time.

The book is more them trying to sell the latest "must have" Barometric watches but it does make some interesting reading.

Keep an eye on the isobars during the TV weather forecast, thats the blue (low pressure) or the red (high pressure) arrows. It gives you an indication if what to expect.

In simple terms high pressure is calm and sunny, low pressure is wind and rain, very low pressure is stormy, then there are moon phases

Thank you so much now i understand what he was going about

cheers again

Or indeed check out weather forecast on this site prior to arranging fishing.

Look at far right column this is the pressure in millibars, as you can see the figure is rising progressively from wednesday to saturday, hence me postponing fishing trip tues/wed untill fri/sat. It does matter that much!
When pressure starts to rise salmon and trout are more likely to be "on" than when pressure is dropping.
Conversely I have found that pike are "on" when pressure is dropping!

A few years back, I got this book fro xmas, and I also bought a Suunto computer watch with barometer which shows the pressure in mb plus a 6 hour history of the trend. I checked the times I fished both still and river (though not salmon) and except for one occasion I can't say that the fish taking was any better on a rising barometer.
I used to plug/jerkbait for pike however, and did notice that they went crazy when a storm/rain was approaching.

Cheers

According to some, pike feed more heavily when the barometer drops as they are preparing for harder times with rain leading to high flows and coloured water.

I kept a check on the barometer and the phases of the moon all last season to see if there was in it - I found there was no relationship at all. Wind and two or three days of settled weather seem to have effect.

LOL... Flippin Jocks talk too fast eh Mitch.

I dunno if there is much mileage in the rising glass/falling glass theories.However,I do feel that fishing is better during a period of settled weather conditions rather than changeable.

I am firm believer in the barometric pressure effects on the feeding of the fish. It isn't fully undrstood, but is believed to be the effect of the swim bladder of the fish. Whatever the reason, it is indisputably a factor that when the pressure drops, before a cold front, the fishing goes a little off. As the front passes, the fishing improves, and once the front has passed completely, it's back to normal.
