Crayfish trouble !

Thanks all, seems like a diversionary attraction tactic is the best option ! Its a pity Cormorants don't like them !

I have had great problems with signal crayfish when fishing on the Derbyshire Dove.Last season I had some success by fishing artificial nymphs with a cage feeder.I caught both chub,barbel,grayling and had a good roach on hare ears and pheasant tail nymphs.Has anyone else tried this? The signal crayfish on the Dove are riddled with some kind of worm so any that I drag in are humanely destroyed and not eaten.

Cormorants, Grebes and Herons do eat them - subject to size - claw size that is!

A small stream, a tributary of a tributary of the Lower Thames, had all it's native White Clawed Crayfish, well over 100, die in one day due to a roving Signal Crayfish giving them the 'pox'. A whole colony became extinct.

They are dreadful things and have totally taken over the Wensum in Norfolk. One redeeming feature is that the otters love them, lots of evidence of cray remains around the otter runs.

Nuts..... they don't eat nuts... Tigers or Brazils preferably... you could try maize over a bed of Hemp as well

Knew it ! the one solution and I can't use it, nuts are banned on this water !! will try maize though, thanks Bluelabel

They do eat nuts -all sorts of them!

Puncture 2 tins of dog food and put one either side of the swim.

I caught my first crayfish the last time I fished my local canal - line caught round its legs. I didn't know we have to kill them but I trod on it. A shame it makes little difference. It would be good if someone could come up with a method to exterminate them.

I mentioned this in a previous post but this recent news may have a touch of optimism in it...

On the subject of Crays, which I raised a year ago, had an interesting chat last night regarding the presence of them in the Wey. Apparently their numbers reduce as you get nearer the Thames, which it is alleged, is because another invader, the Mitten Crab, scoffs them up !!!!

Have also heard that trouble with crays on the Thames has also reduced, could the Mitten be fighting back !!!!!

What do you reckon, hearsay or fact ??
