A: Michael Thomas from Marina asked, "I love to fish, but recently I have been hearing that the moon phase and barometric pressure has a big affect on fishing. How does this make a difference?"
It is important, however, to note that the effects of barometric pressure is greater in fresh and shallow waters, than it is in deeper waters. This is probably due to the fact that the pressure of water is so much greater in deeper waters making the air pressure above it no longer having any significance. The following is a chart that I found concerning Fish trends vs Pressure trends.
The barometric pressure is just one of many factors that effect fish feeding habits. Other effects include water temperature, light, tidal forces, water clarity, the pH level, water levels, wind/surface disturbance, boat traffic, fishing pressure, and so on. Another good judging factor of fishing is the so lunar effects which play a role in the tidal and illumination factors
