I wish I had my wee sample bottle today – I am pretty sure I witnessed a hatch of Grannom in the Kelvin – I kid ye not!
In spring, the first sedge fly of real importance to river fishers is the grannom, and it causes great excitement both on chalk streams and on rain-fed rivers. The grannom appears in April and the main hatch usually lasts for ten days or so, with flies coming off the water from mid morning until late afternoon.
Trout tend to ignore small upwinged flies when the grannom is on the water, but as other sedges are rare at that time a close imitation is probably unnecessary: any small sedge will do.
I have never been lucky enough to witness a hatch of Grannom on the Clyde so when I seen little black sedgy type things fluttering around I was a bit unsure as to what they were – I suppose even if I did actually have my sample bottle there would have been a problem as I could not catch one to take a photo of.
I think this is why getting the hatch chart off the ground is so important – I know it will take a fair old amount of time until we actually have something resembling a month by month chart however it is going to be fun and informative while we do it.
If you have not already done so check out the Kelvin Hatch Chart thread for progress so far.
Even if it was Grannom the trout did not seem particularly interested – I caught a couple of trout on an enormous deer hair emerger (it was my indicator) and lost a couple.
It was a lot bigger – its yellow funnel was gone – I think maybe it was past the point of releasing its seeds – whatever – I stomped it into oblivion – and then pulled its roots out for good measure!
Weird plants – do not mess with me!
