I don't think the article meant it to seem cut and dry. At the bottom it mentions several other parameters that may affect fishing as well as barometric pressure (temp., salinity, pH, etc.)
For the most part I think it was saying what most of us already realize.
High pressure sucks for fishing, usually.

Based on Physics, I'd have so say no.
Just quickly run over the basic forces at work here. The "weight" of the atmosphere that we feel at sea level equals approximately 15 lbs of force per square inch. In terms of barometric pressure readings, 30 inches of mercury equates to this 15 lbs of force, or 1 atmosphere. So, if the normal range of barometric pressures go from a low of 28.5 to a high of 30.5, that is only going from 0.953 to 1.019 atmospheres of pressure (or 14.3 to 15.3 pounds of pressure differences).
Not a dramatic range.
Now think of the "pressure" underwater, that directly effect the fish. Water weighs far more than air. Right at the surface, the force of the atmosphere would be felt, so the pressure would be around the 15 lbs resulting from the atmosphere. But, for every foot you go down, you add around 1/2 a pound of pressure. So by the time you get to 33 feet, there is "pressure" felt that is equal to 2 atmospheres!! Double the pressure felt by the most extreme of weather in the atmosphere. And for every 33 feet you keep going down, keep adding another full atmosphere of pressure.....
Now contrast that to the first part of the General Rules presented in the article:
High-Clear skies-Fish slow down, find cover or go to deeper waters.
Huh?  If the fish don't like the higher pressure, they would move to deeper water INTO a higher pressure environment???
(Before you flame me for this response, I'm approaching it from the same aspect that the article author did, completely ignoring the physiological differences in how "we" and "fish" perceive pressure in fluid medium).  |

That's a good point. I've read and it seems to make sense that the blue bird skies that follow a cold front may force the fish deeper and the water changes temp the fastest at the surface, so the fish may be moving away from that fast change as far as they can get.

Of course there is no rule that applies to all fish all the time. At least not yet. I'll let you know when I finish my theory of everything.

I was thinking along the same lines CS. I think it is more the things that typically are associated with low/high pressure that have a compound affect on fishing. ie sunlight precip temp... not the actual response to the slight change in pressure.
And aaron, I would disagree slightly. There is one rule that applies to all all fish all the time:
If you don't wet your line, you won't catch fish.

I've learned from good ol' Capt. Mike, that pressure has more effect than I had previously given credit. High pressure is definitely my least favorite. I know I sure would like something to blame my poor fishing luck on. I jumped out yesterday hoping that the low barometer was going to equal a better bite. Nic and I had gone out to the KRS on sunday and drifted with soft plastics and only picked up a few trout with the barometer up. Certainly nothing report worthy. Yesterday was no different despite the change in conditions, and both days I found bait and good water with grass and sand pockets in 2-5ft of water. I know a big part of my bad luck was the inablitly to change up my game plan. Both days I had Nicole with me and was unable to get out of the boat. I think that would have made a big difference. I also did not give much effort to fishing deeper and who knows.....that might have been the key. I hate fishing deep and I hate fishing slow. And that's all I have to say about that.

no worries island mike, I fished deep and slow at 3 different spots yesterday, at two different times of day yesterday (overcast and misty in the morning, clear as a crystal at sunset) and got nada as well. So it probably wasn't your game plan,and it probably wasn't the pressure either. Still searching for things to blame it on... maybe the dog...

I stand corrected.

So far we have a scientific info, Physics info, Game Warden input.
Capt Mike, Capt Rowsey? Any professional experience on the matter?
I know when we were out yesterday we started wading a shoreline (Around Noon) there was Cloud Cover and fog. As soon as we found the nervous bait we were looking for we started catching trout immediately on Top water’s and suspending Mirrolures. This lasted for about 25 min and then the Sun came out and the fog went away the bait became considerably less active and we did not receive another bite the entire day. We moved to deeper water after about 2.5hrs with no bites and the results were the same. I'm always curious as to why things just shut down somtimes. I know if we had been there 2hrs earlier we would have put on a clinic on those trout. |

You just ain't holding your mouth right!!!
That is my most scientific assessment of the situation. |
