"'Everything in the water either sinks, floats to the surface of suspends', says
Hugill. 'Few anglers give it (barometric pressure) much thought, but a change
in barometric pressure is to a small degree like a change in gravity.'"

Follow up quote today.

"Plus because object weight less in the water, the affect of a pressure change
is far more pronoun ed beneath the surface than above."

I'd call that some "serious" food for thought....DemoMan
Never thought about it that way. But sure will start now.

Here are a few more on the same subject.

"A 1-inch square column of air, measured from sea level to the top the
atmosphere, would weigh about 14.7 pounds. Multiply that; by the surface of
your favorite fishing hole and you've got serious pressure. So much for lighter
than air."

"'Fish are extremely in tune with their environment,' he explains. 'They have an
incredible array of pressure-sensing systems-such as the lateral line- that key
them in to changes in barometric pressure, which in turn could signal feeding
opportunities or foretell the arrival of a major water change.'"

"For example, a drop in pressure can cause tiny particles of sediment and other
material to float off the bottom or rise higher in the water column than they
normally suspend-particularly when currents are involved-slightly reducing water
clarity. but more importantly, it can affect tiny creatures such as
zooplankton and phytoplankton-the building blocks of any respectable aquatic
food chain."
