CALLING ALL FISHOLOGIST

fish still have to eat every day to survive regardless of the weather.

WE ARE ALL SITTING HERE WAITING ON THE ATMOSPHERIC INTELLECTUALS TO RESPOND BRO....LOOKS LIKE SOME PRETTY COOL ANSWERS SO FAR....


STANDING BY FOR THE NEXT FRONT OF REPLIES TO MOVE IN....

I would prefer to fish during a falling barometer, but, it may have more to do with other effects other than pressure itself. When the barometer drops, what else usually drops ? Temps, rain, clouds, and not the wind.
Predatory fish may feed better because the low pressure weather better suits their ambush style of hunting. Maybe the low light conditions make the predators themselves more at ease and more active? Who really knows?

All I can tell you is the bluebird days are comfortable for us, but I have always done my best killin' during the nasty stuff.

were on the boat for at least 2 weeks twice a year to collect fish for the aquarium and I asked them ten million questions. They said the drop in pressure put less pressure on their swim bladders thereby making them hungry but tuna dont have a swim bladder...

A drastic drop in pressure like a hurricane is like 8' of depth change. I call BS on that theroy. On the dropping pressure the water tends to have better vis, as well as a signal to hide out. The fish that don't hide or couldn't make it usually end up in the monster fish bellies. Because the large mature predators like GBFT Marlin big sharks etc have the stamina as well as the experience to exploit a food source that cannot withstand the churned sea conditions presented during a weather front.

but I don't give much merit to the churned water theory.

I know that when a low is moving in and we are tournament fishing looking for kings we are fishing off the beach in deeper water.It seems to me its better fishing a few days before and after a front comes in.

Why is it that the 3rd day after a big change in the barometer then. This was brought to my attention when I first started fishing over 40 years ago. As the water settles the particulate drops out. Afternoon winds caused by thermal changes do not churn up the water like a frontal storm. If it did we would never have clean water. The swell created by a drop in pressure churns the ocean from the seabed to the surface. One of the reasons why sight feeders are better 2 days before the storm and ambush feeders the day it's going to hit bite best

Perhaps this will help
Description Deep water wave.gif

Stokes drift in deep water waves, with a wave length of about twice the water depth.
Description of the animation:
The red circles are the present positions of massless particles, moving with the flow velocity. The light-blue line gives the path of these particles, and the light-blue circles the particle position after each wave period. The white dots are fluid particles, also followed in time. In the case shown here, the mean Eulerian horizontal velocity below the wave trough is zero.
Observe that the wave period, experienced by a fluid particle near the free surface, is different from the wave period at a fixed horizontal position (as indicated by the light-blue circles). This is due to the Doppler shift. So as you can see the deeper the less effect the waves have, consequently the bigger/longer the wind is blowing a hooligan out at sea the more the energy within the wave will penetrate deeper water and suspend any particles. Due to the shorter wave length, things cannot "drop out". But the Hydrostatic pressure change in a rapid secession can effect fish with swim bladders greatly, as a BIG wave go's over,the pressure change can and is very rapid, bigger the wave bigger the pressure change.
here a more eraldite Dr, has put it perfectly
