Hey (again)

Well i've managed a question a day since I joined and here is my 3rd

Does air pressure affect feeding or behaviour of trout? I constantly look on BBC weather and notice its average is around 1010mb and some days it goes to 1025mb. A quick guess by me says this will affect them BUT in a good or bad way?

Rapid change seem's to put them off for a while.But steady pressure whether high or low.seems to settle them into a feeding mode,in my experience.
Remember that changes in pressure normally mean change in weather/wind direction/rain/temprature.

Yeah a 3lb grayling said. Normally a sharp rise or drop in pressure really puts the fish of the feed.

So when a heavy thunder storm rolls in the fish can drop right off for a while.

it has been said in the past and i dont know whether is 100% true or just a myth that really sudden changes can kill fish. But could be a total lie as i have never witnessed it and dont know anyone else who has either.

Never heard of that myself Andy, but certainly water temperature shock can kill a trout stone dead. 5 degrees C sudden change is enough.

Interesting about the thunder storms, as it's more likely angling pressure is first to cease during such weather, but I would give my right arm to be on my favourite pools 5 minutes after such a storm. Fish seem to be mad as a box of frogs after an electrical storm, so I wouldn't find it hard to believe that the build up pressure to a thunder storm could affect them too.

Anyone else find it uncanny that so many good pools lie directly under electric cables?

pressure will affect the fish's swim bladder. WIll disorientate them for a while, so a big pressure drop/rise will put them off feeding a bit, but a bit of a drop/rise wont make a difference.

Pawprint, impressive post for your third, pressure changes have an effect on all living things, when it drops quickly most animals become aware of rain coming for example, sometimes drops are associated with a quietness as birds and animals stop,
aquatic insects are especially effected by rises because it signals good weather for their after hatch survival, trout as preditors have naturally adapted to feed at these times,
its a big learning curve.

As a boy I had some wonderful catches of Roach during a thunderstorm, I had a cane rod in those days, so just kept on fishing, they went beserk throughout it, and eased right back when it ended, it happened on more than one occasion, so I really do think there is something in it.

I keep quite a close eye on air pressure and it's true - a backing wind and accompanying low pressure front can kill sport stone dead, although as always in nature, there do seem to be exceptions...only last night I fished in just those sort of conditions with the wind backing northwest to westerly and a 5mb drop on the glass (ok, so nothing extreme admittedly), and did rather well due to the fact that a cluster of other circumstances dropped nicely into place.

If you fish for wild brownies on stillwaters its interesting to note sometimes how action can come in spurts. Sure there are a few contributory variables at work here, but air pressure is I'm convinced amongst the most influential. If I make a mental note of the timing of spells of sport and lulls on a given day afloat, it's amazing how subsequent reference to the day's pressure fluctuations (real time weather station data is available online), reveals a persuasive pattern. Even a few mb here and there can appear to tip the balance one way or t'other. I for one am convinced..........on such slender margins do our aspirations depend!


fascinating thread.....

Very very similar conditions tonight Matt, had it not been for the match I would have gone again.
Hope it stays the same for another day, wind virtually dropped right off about 7pm.

As far as I'm aware, a rising barometer brings fish onto the feed.

You can have this info at hand if you have a mobile phone. I use an app called weatherbug, which uses local weather services. In my area they use RAF Shawbury, which is ultra reliable.

Try it and see what info you get.
