How does barometric pressure affect fish?
A fish senses pressure changes through its air bladder.
Fish that have small air bladders don't seem to be as affected by barometric changes as those with large bladders. But remember, forage fish they feed on have air bladders, and that alone could have a big impact on where you might find fish and how they behave. cowgirl wedding items for a country wedding
Fish with large bladders quickly sense when the air pressure is dropping, because there's less pressure on their bladder.
And when there's less pressure squeezing their bladders, the bladders expand a bit.
When their bladders expand, fish become uncomfortable.
They relieve their discomfort by moving deeper or by absorbing extra gas in their bladders.
