Must be the season for articles on how barometric pressure affects fishing.
Two posts feature a common myth to explain why fishing seems to get better when barometric pressure drops.
Sorry, but the above posts about how barometric pressure affects fish have disappeared on the two sites, maybe they read the Midcurrent article linked below.
Both these stories trotted out the apparently solid advice that it is changes in Barometric pressure detected via a fishes bladder that triggers changes in feeding habit. Trouble is there is no scientific evidence for this theory, as can be seen here: Pressure Myth (link fixed)
Now, to clarify something here, the anecdotal evidence is overwhelming that fish often start feeding more aggressively as barometric pressure drops, this being true in both fresh and salt water. But the myth given to explain this behaviour is just that, a myth. It may be a myth that has in fact hindered us from exploring this aspect of fishes’ behaviour more fully, and more accurately
