Yeah its a tough one to answer I think. I have no doubt that varying air pressure co-insides with fish coming on the bite. I have seen it a thousand times myself. I have fished many a reef before a storm and its been the best fishing I have had. i.e low pressure.

Then I've also had awesome fishing during a constant high pressure aswell. We've all no doubt experience good fishing in varying pressure scenarios.

But, I think its to hard to say what role pressure plays.

As I mentioned earlier. Maybe its the other prevailing weather conditions caused by the change in pressure that bring the fish on, who knows?

But I dont think anyone really knows for sure.
