Crayfish

[crayman]

I'm interested in catching some signal crayfish for the pot, What is your view on them?, do you see them as a pest?, do they help or hinder fishing?.
Does your club have an infested stretch of river were i could trap them?, i would of course pay all subs & respect rules & regs, just not fish with rod & line like the rest of you.

I look foward too your comments
