Well looks like this high pressure just gonna hang in here. Hope we get some weather soon that will lower it.

Most believe high pressure wrecks fishing while low can trigger it. Well it's extemely high now and fishing is slow. I see rain is in the forecast for Wednesday which should mean lower pressure. My fish graph if you believe in them shows poor today, average Tuesday, Good Wednesday, Good Thursday, excellent on Friday!, good on Saturday ,and average on Sunday.
I think that when the BP does the most damage to fishing is when it is unstable. It affects their air bladder in a way that is uncomfortable for them and they shut down. Even an extremely high BP can be productive if it is steady, you just have to look deep where their bladders aren't as effected by the high pressure. Not saying that the fish aren't in those shallower waters, but good luck getting them to bite. The oppisite is usually true for low pressure systems, especially right before a storm/front. I have caught them just inches below the surface in the dead of winter right before a front. This is just my opinion by the way, but it has been a very effective way of getting me on the fish more quickly and cuts out a lot of guess work.
I always seem to to do just before a storm front as baromentric pressure drops. Behind a front with bluebird skies and high pressure is the worst. Sometimes after 3 days post front fish fire back up, guess they get adjusted.
I think that is because the pressure falls and evens out just before a front. Then it starts climbing again after the front and is unstable for a couple of days. If you have a graph that predicts BP, look for those steep climbs and falls followed by an evening out period. My best fishing comes when that "lull" happens in the 29.80-30.15 range. Ever notice that the fish suddenly turn on for a few minutes, then turn off like a light switch? I would bet that your graph will show a rise or fall in BP with a period of stability during that time. Again, JMO but I have found this to be true 90% of the time. But hey, i'm still learnin!
I wonder if BP affects humans. I need something to tell Mrs DP when I don't want to work on the house.

Latest SPC U.S. Composite Map
Here is a link to a good weather map tha will show Highs and Lows plus fronts and wind. I use it on the farm to see where weather fronts are.
There is a big low heading our way. But if we heavy rain it will mess things up .
Roughneck that a good map. I think I got go back to school to learn how to use it.
Me too! All them squiggly ines sure are purdy though!Quote:

Here are some science facts you might be able to apply concerning barometric pressure and fish behavior:
A. The volume of a gas varies directly with temperature and inversely with pressure. A sudden drop in pressure results in an increase in gas volume and an increase causes the gas to expand.
B. The gas in a fish's swim bladder is pure oxygen. Too add or remove gas from their swim bladder is done by taking it from or giving it to their blood stream. (No they don't expel gas like we do nonono!!) This process takes considerable time..... days not hours.
C. Fish are lazy, they want to save their energy for basic survival, and therefore will suspend at a depth where they have neutral buoyancy rather than having to continually swim up or down to retain a certain depth.
D. Changes in pressure have an immediate effect, but water temperature changes are slower in most cases so fish have more time to adjust to temperature so behavioral changes are also slower.
So..... when the barometer drops, the fish will start adding oxygen from its swim bladder into the bloodstream. These higher oxygen levels will give it increased energy causing increased activity (often devoted to searching for prey). Dropping pressure will also immediately cause the fish to move shallower to be at a depth providing neutral buoyancy until the longer term bladder volume changes all a return to their preferred depth (usually where food or shelter is available).
When the pressure increases, they go deeper to suspend and begin to slowly add oxygen from their blood to their bladder to be able to return to their preferred depth. Lower oxygen levels in their blood results in lethargy and inactivity.
Bottom line is go fishing anyway! Just remember that when pressure is falling like before a front bite is likely to be shallower and better than the day before, and when higher fish are deeper and bite will be slower. Watching the barometer can give you some idea what the fish may be doing, but it is not the only change that affects the bite.
Good reading.
Well , the theory worked today , culled out a limit anyway.
I never got a bite. There was 6 other boats there with no fish when I was there. 98 bridge Conway
Well I didn't get skunked but only 1 crappie and 4 whites for us down on Little River, other boats were saying same thing, fish were biting back before Christmas but not now. I hit a lotta tops up and down from White Cliffs Rec. area from nearly to Jacks Isle up to about Brown Slough. Fished til the rain ran us off around 2pm.
High Pressure means deep water....thats where you will find em bitting.

I always have to know "why". You have explained it. But, I ain't never going to remember all of that stuff.

I dont need to know why, i just know it works. Hey, if the fish passes gas at 6:23 a.m. EST and then goes on a feeding frenzy at 6:25, why argue with science?
This really good info, and from a scientific perspective, it's make perfect sense.
Best info in the world is how full or empty is the ramps and what others say about the recent fishing. Dad went by these two for a long time and you can just about bank on them. If guys aren't out fishing for em they prolly ain't a biting.
Ramps were not full today! We brought in our limits too!
From my experience on Conway, I'll use Caney Creek for this, the people don't show up, until they hear of someone else catching them. There are a few dedicated guys there all them time, but it's usually not packed until the word has gotten out that they are biting. Same goes for just about every popular spot on Conway. Just cause folks aren't there, doesn't mean the fish aren't.

Really great info here. I'll have to read it a couple times to fully understand it, but i'll get it eventually. Thanks fellas.
it 29.90 today. Be a great day to fish it you stay on the water with this wind
Here is an article about green carp behavior and responses to pressure changes. Says you may as well throw out the barometer and go fishing......:dono. Just have your rain gear if it's falling fast. Then again, crappie are probably smarter than carpie.
BAROMETRIC PRESSURE AND BASS - In-Fisherman
Something as way wrong yesterday, only caught 16. Water was muddy and coming up though. Wind got up preventing us from fishing long, dads boat needed many adjustments, dead trolling motor, screwed up trim switch....it wasn't a good trip other than we did get the 16 crappie. It was right after that front also which prolly didn't help. Weather patterns have been screwed up like the water levels recently too.
