How does barometric pressure effect fishing

[CrappieKeith]

Here's an article to start out this thread.

Bass & The Barometer
You can ignore the effect air pressure has on bass and go on pretending it doesn't matter. And You'll go on being wrong!
What Makes Weather: "Weather" is caused by uneven heating of the earth's surface. Warm air is lighter than cold air, so it rises. Rising air would create a vacuum, but nature won't permit that, so surrounding air rushes in to fill the void that rising air is trying to create. The result is "wind". Also, its the warm air, rising air in one area, and the cold, descending air in a different area that creates differences in air pressure, i.e. barometric pressure, and at any given spot in the world this pressure is constantly changing. We humans seem a bit out of tune with barometric pressure changes, as they don't seem to affect us as much, at least outwardly. Do these pressure changes affect other land animals?

Very interesting information Keith.:icon_cool:
It has been my experiance that the high pressure means a tough bite.:confused0024: Now I better understand why.
Ours is finally falling at this time, might be better this afternoon. Thank you, Mike

IMO pressure changes effect the deer :confused0024: Kirk

You bet it does.
I've seen deer really active before a front.
If the deer are out in the fields prior to an evening walleye run I know we are in for some good fishing.
The birds are real active at the feeder too.

Fishing in high pressure is ok if the pressure has been there several days.Fishing will also be alright with high pressure if the barometer is moving up or down.
There are 3 moods of fish positive,nuetral and negative.
Pressure will be 1 indicator I'll check to get an idea of upsizing or downsizing.
Upsizing means bigger baits and faster presentations vs downsizing and slowing down the presentation.

Thanks for sharing the information on using the barometer to help understand the effects of air pressure on fish. It has really helped my fishing to pay attention to the these subtle differences. I understand more about size selection and how to effectively present lures to the fish and how much things can change. :icon_biggrin:
