I heard of this some years ago while coarse fishing. I started to take note of air pressures and 90%+ of the time fishing was far better when there was periods of low pressure. I am no scientist and it could be that it was just coincidence but I did this over a number of years and the low pressure far out fished the high pressure.
Have not heard anything about the pressure affecting fishing. A good idea is to keep a fishing log. Include the following weather, tide height and time bait used fish caught weather you could include pressure at the end compare each day you go fishing and you sometimes get a rough picture on when the best conditions are.
Yes, it's a scientific fact. High pressure affects all marine life adversly, and puts fish off feeding. The air pressure on the sea increases water pressure on the fish. They are ultra sensitive to pressure. Best time to fish is when pressure falls after a long period of high pressure.. Metcheck gives daily pressure readings with the weather .
One reason why fishing is mainly useless in fine sunny weather. fine weather = high pressure.
