Ardrossan Pier (Lighthouse) has been out of bounds for angling for years now but you can still fish the back of the harbour wall. Rough ground for dogs, small coalies / pollock / codling with best baits lug and rag. Wrasse fishing can be good here at times with float fished rag close in best for fish to 2 or even 3 pounds although they average under a pound.
Saltcoats not as good but similar fishing.
Good light tackle float fishing in summer (July onwards) in the inner basin at Ardrossan for Mackerel and coalies.
Nothin in salcoats hasnt been for years.
Im part of the saltcoats sea anglers club and we go to ardrossan at the back of the wall.
Years ago saltcoats was good for fishing but not now.
Best going to dunbar for good fishing.
