Affect Fishing Results What Is Barometric Pressure

Every angler usually knows how the tides, temperature, lighting level and moon phase can affect our fishing results.

However, there is actually another factor that is often not taken into account at all, which is barometric pressure.

Although barometric pressure (or atmospheric pressure) cannot be predicted as precisely as other elements, it is able to exert a great influence on the attitude and behavior of fish.

How often do you enjoy catching fish before a bad weather or storm

Or have you ever experienced a mysterious situation when the Phone Number List fierce fish suddenly went silent as soon as bad weather arrived?
And how long will the fish come back after the storm has passed?

Barometric pressure means the weight or mass of the entire column of air per unit surface area at sea level.

The barometer is also a tool for observing the weather, because its fluctuation shows that the weather is changing.

Liquid mercury (Hg) is commonly used in barometers to measure air pressure changes in inches (in.).

Atmospheric pressure (air) may also be measured in millibars (mb).

Where one ‘bar’ roughly equals one atmospheric pressure (one atmosphere equals 1.01325 bar).

One bar equals 29.60 inches of Hg.
A barometer that reads 30 inches (Hg) is considered normal.
Strong high pressure can reach as high as 30.70 inches.
While low pressure associated with hurricanes can drop below 27.30 inches
Usually weather conditions such as cold wind, hot wind, or rain – will cause low atmospheric pressure.

Briefly A high barometer reading lowers sea level a low reading increases sea level

On the other hand, high atmospheric pressure usually USA CFO occurs after the weather mentioned above has passed.

When high pressure occurs in an area, it usually means sunny days and relatively calm seas.

How does barometric pressure affect fish?

Fish detect changes in pressure through their air bladders.

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.
