I think the main factor that affects the fish is the penetration of light, I think it actually hurts thier eyes if they get toomuch. I think the rain oxygenates the top of the water, and causes them to rise in the water column. The reason for lack of feeding on a bluebird day after a front, is probably because they ate like kings during and before the front, when the skies were cloudy ,and the temp was cool, and they had more places they could roam and feed because of the lack of high light penetration during the front. Same reason crappie hang on the top of brushpiles in the early AM, the light isnt very intense, then as the day progresses they go deep, same reason they go to bridges at midday,.. the water temp doesnt change that drastically, especially a few feet below the surface, but the light penetration does. If you leave a live crappie in a bucket exposed to sunlight, the vessels in his eyes will burst, thats the red blood lines you see. thier eyes are sensitive.

I completely dissagree with tommy. I have caught lots of good fish with pressure that high or even greater during the winter. I know it effects the fish but I wouldn't stay home because the pressure is so high. The pressure gets that high all the time so I would have to think they are semi use to it. I think of it like allergies, people have allergies all the time but they don't stop everything because of it. They find a way to live with it.
