When the barometer is low or falling, fish will spend most of their time equalizing their air bladder, and the last thing they're thinking about is feeding. When this happens you'll have a difficult time fooling a fish into eating. On the other hand, when the opposite is true, and the barometer is rising, your chances of catching a fish, is far greater, because they feel more like eating.

Fish and wild life know what to expect from the weather and can sense when a storm is approaching to a much greater degree than we humans can. You’ve probably noticed that when the weather is nice all of the critters outside are active and frolicking about. This means that the barometric pressure is stable or high. On the other hand when the barometric pressure is low, you won't see nearly as many animals around and the ones you do won't be frolicking anywhere. Even the cows in your local field will be lying down. At times like this it can get pretty quiet out on the lake or river too. The fish just aren’t active.

Understanding how fish adapt to changes in their environment allow an angler to better predict a fishes' movement and feeding. Finding out when a fish is feeding is what we're interested in because that's when you have the best chance of catching said fish. You may know that almost all saltwater fishermen check the tides before they head out fishing. And it’s a great strategy because the tides impact fishing. But you do realize what causes the tides to change, don't you? That's right, the moon. And the gravitational pull of the moon that impacts the changing tides is also pushing against some part of the earth all the time. So the pressure is always there but since water is more easily moved than the ground, water is lifted up towards the moon causing the tides to change. How high the high tide will rise or how low the low tide may go is largely determined by the position of the moon and sun.
