How to catch a gudgeon
Gudgeon are a relatively easy fish to catch and match anglers in particular are very adept at catching several hundred during a competition. They can be caught on the towpath side edge, fishing no more than a couple of metres from the water's edge, on or just off the bottom. Alternatively, fish on the far bank using a long pole or waggler tactics. A single pinkie or maggot is as good a bait as any. Hook size needs to be small, a size 20 or 22 being ideal. Gudgeon are particularly attracted by sweet-smelling ground bait, with feeding on a 'little and often' basis.
