Anglers have known for a very long time that barometric pressure affects fishing. Its changes seem to affect fresh and shallow water fishing the most. Barometric pressure is basically the measurement of the weight of air and a barometer is used to measure it. Barometric pressure changes along with the various weather systems. This is noted on weather charts as highs and lows. Not only do these changes allow the angler to know when the fishing will be good, but also how to fish.
Barometric pressure affects fish in shallow water more than fish in deeper waters. It's thought that this is due to the pressure affecting their swim bladder. A fish's swim bladder controls its equilibrium. When the pressure is high the swim bladder compresses and the fish looses its sense of balance. It's thought that this makes the fish feel uncomfortable. When this happens the fish are less likely to feed and the fishing will be poorer.
Low Barometric Pressure Fishing
You've probably heard it said that it's best to go fishing before and after a storm. There is truth in this statement. During these times the barometric pressure is lower. When the pressure begins to fall and the skies are cloudy, fish tend to be more aggressive in their feeding habits. Once a storm has cleared, the fish will also feed, though prolonged storm periods may slow the feeding down. If this happens, you may need to try fishing in deeper waters. If the pressure is normal and stable, fishing will be normal.
High Barometric Fishing
When the barometric pressure is high, fishing probably won't be as good. During high pressure conditions, fish are usually seeking cover or moving into deeper waters. As the pressure begins to rise, you might find the fish slightly more active for a short period of time. During these high pressure conditions, it's best to try fishing in deeper waters or where the fish are seeking shelter.
