ok, here is my "Opinion" on the B-Pressure. Im a full time Multi-Species Guide here in DFW. I target everything that is catchable with a rod and reel, and this goes for almost all the fish I target. I seem to see the fish are more affected in 1-15ft of water by the air pressure getting wacky on you.

I like it 29.85-30.10

Slowly falling or rising .01 at a time or just holding, like:

29.97
29.96
29.95
29.94
29.94
29.94
29.94
29.95
29.96
29.97

If it falls .02 or more every hour, the fishing seems to be always get slower. If it's to high or even to low, they will shut down. Nothin you can do about it, but it will tell you a little reason to why ur not catching anything. If it's 30.40 and above, I will cancel your trip. Not worth the time to fish high pressure systems. The day after a cold front is always a blue bird crystal clear beautiful day, but 99% of the time the air pressure sky rockets and the fish get affected by it and will get lock jawed. I fish 2 days after a cold front to let things settle down a bit. I am on the Bass Pro Shop's Pro Staff, so I hang around the store a lot doing seminars and stuff. So I get to see the fish first hand in the show tanks as systems roll through here and there. I have noticed the Crappie will lean on structure when the air pressure is super high, 30.40 and up. When the pressure comes down, they spead out a bit and hover again. So im my opinion, it seems to mess with thier swim bladders in a way that makes them uncomfortable.As the bite shuts down, look at what the air pressure has been doing. I bet im right! -But again, all my opinion.

Tight lines.
