Can anybody help me with my problem, I live in north Northampton and I am having trouble finding crayfish to trap. I have the proper trap and have even tried bait bags to check the river first but still with no luck. Any good rivers anybody could name for me as I've now just ruled out the Nene and the Ise River.

check with your local waterways dept they will know were you will find them. or ask local fisherman as they will have come across them
