Fish with small air bladders (eg pelagic fish such as Mackerel and Belitong ) are often less affected by changes in barometric pressure than fish with large air bladders.

This is because the fish with a small air float has a body density that is almost the same as the water in its environment.

They cannot detect sudden changes in pressure.

So, their comfort level does not change drastically.

However, we need to remember that many of the prey fish that these fish hunt also have air bladders.

So this can have a big impact on where you can find them and how they behave

For fish with large air sacs for example Jenahak and Grouper Latest Mailing Database they are more sensitive to the drop in air pressure.

This is because there is less pressure on the air bladder.

When there is less pressure on the air bladder, the air bladder of the fish will expand a little.

When the air bladder expands, the fish will start to feel uncomfortable.

They try to relieve their discomfort by moving to the lowest level or by absorbing the extra gas in their air sacs.

As a result of experiencing anatomical and physiological stress, these fish do not care about eating anymore.

They think more about how to find a depth where they can balance the pressure of their air buoys and start to feel comfortable again.

Some species will settle to the bottom and cope with the change by living near the structure.

In general fish will be more comfortable when the pressure is high and stable

They will tend to actively search for food in various Buy Email List water depth columns.

And with drastic weather changes and high and low pressure cycles – it definitely changes how fish react to pressure changes.

Once the storm has passed and the pressure begins to build, the fish may not feed aggressively for at least 24 hours, as they are still in the process of acclimatization.

However, the fish will become active again after 1 or 2 days after they have stabilized themselves with the surrounding pressure.
