read something on here before about a balloon and a fishes stomach. high pressure fills up the balloon=not hungry. low pressure lets air out of the balloon-makes room for food.

that has stuck with me and its the only way i can remember it.

Fish both days and post your results.

I could be wrong...but if there is a high barometric pressure, wouldn't the high pressure cause the air bladder to shrink from the high pressure pushing against it? And then with low pressure since there isn't near as much pressure as their was, I would think that it would cause the air bladder to expand from lack of force from pressure. Alot like when you catch a catfish in deep water you need to "burp" the fish since the water pressure decreases as you reel the fish in and he gets closer to the surface which causes the air bladder to expand and the fish cannot release enough air fast enough which can cause the fish's stomach to protrude into its mouth.. .maybe I'm wrong, but it makes sense to me...I think that any rapid or drastic change in a catfishs environment in a short period will cause the bite to stop due to catfish needing to adjust and stabilize due to their body's sensitivity to so many conditions of their environment...a lot like when the bite turns off for a few days due to the lake the fish are in starting releasewater from its spillway...just my $0.02

I read a very detailed article evaluating the effect of barometric pressure on fish from a scientific point of view.The long story short , the amount of air pressure change, that it would take to affect the pressure of water to a noticeable level by fish would be tremendous, the amount of pressure change they see by moving up or down 1 foot in the water column was greatly more than a full point of the baramoter would make.
Bottom line was that it was very unlikely fish ever notice a change in the baramoter but more likely are affected but the weather conditions associated with pressure change.

I will see if I can locate the article and post it up, much better explanation than I provided.
