Barometric Pressure

[DockShootinJack]

I know the barometric pressure has to do with the swim bladder that fish have. Too much pressure on the bladder makes them uncomfortable. Being a scuba diver, I think the fish would just change depths....but they still have to eat.

I would think a fish could regulate that bladder quickly enough. Yet when driving up and down the mountains around here my ears become uncomfortable until they pop.

But when your ears pop and your hungry you still eat correct?

Absolutely. I figure for the fish much like ones ears needing to pop the discomfort is only temporary. I feel a fish as with all animals they are meant to eat, to put on body mass. In the animal world being fat is a good thing. That animal has managed to eat in enough abundance to have body mass to see it through hard times. I would think there are times and conditions that cause fish not to actively chase down food, put a jig right on it's nose and it will eat it. I have caught crappie gorging themselves in shad that have a shad hanging out of their throats, yet they still took a jig or a minnow. I would also think that is the main advantage to livescope. The ability to deliver a bait right in the fishes face. That fish may not chase a jig 2 feet away but when that jig is mere inches away, all the fish has to do is inhale and take the jig. It can be called a predatory responce, whatever it is that fish is hardwired to eat to become a bigger fish

I think Barometric Pressure, in general, has an effect on all species of fish with a swim bladder. Those fish are ultrasensitive to change to their environment; pressure, water temp, turbidity etc. I will say that in my experience a dropping pressure is better overall, then a rising pressure or super high pressure. But that doesnt mean they dont bite- it just means patterns may vary. One of these days im going to keep strict data on catch rates etc and pressure to really do an experiment.

Shooting docks I have noticed on those bluebird days they were high in the water up under the darkest parts of the docks. The darker the better. If anything it concentrated the fish on those days. Makes them much easier to catch. On overcast days they will be more loosely related to those same docks. I am sure it is more a difference in the amount of light penetrating the water that it is the effect of the barometric pressure.
