Fly life and fish activity

[Deleted]

My last few visits to my fishery have been frustrating in that there has been a lot of fly-life on the surface but virtually no interst from the fish. This tends to happen each season and I was wondering what the reasons are .Could it be fish take time to connect that flies on the surface are food but as they had none over Winter take time to remember? Could it be that there is still adequate feeding on the bottom or when the nymphs start to climb towards the surface? Could it be as the water is cold that their metabolism is low and thus they do not, or need, to feed actively and only when the water temperature passes a certain level they feed (or dissolved oxygen)

Don't know the answer, but sure as anything recognise the phenomenon!

I've been breathing grannom on my last thre trips to the Culm.

Last visit was the first time there was any surface activity at all.

Sadly the result of covering the activity was three trout <3" and three chub c. 6"!
