While barometric pressure may not directly affect the fishing conditions, it is a major factor that can influence what a fish may be doing at any given time.

How does a barometer effect fishing?
A fishing barometer is a tool that measures barometric pressure in the atmosphere. Anglers use them to help predict the times when fish might be biting. Studies seem to show that barometric pressure has a direct impact on the feeding habits of most fish, though the impact seems to be more pronounced in shallow water.
How does barometric pressure affect fish?
In addition, freshwater fish seem to be more affected by barometric pressure than saltwater fish. Barometric readings seem to affect all animals to a certain extent. One theory suggests that during times when barometric pressure is low, there is slightly less available oxygen.
What happens when barometer falls?
In frosty weather, the fall of the barometer denotes thaw. If wet weather happens soon after the fall of the barometer, expect little of it. In wet weather, if the barometer falls, expect much wet. In fair weather, if the barometer falls much, and remains low, expect much wet in a few days, and probably wind.
What is the range of barometric pressure?
Barometric pressure, an indicator of the weight of column of air, ranges from an historic high of 32.01 inches to an all-time low of 25.9 inches.
