I think the key to canals is pre baiting if going for it full time the fish can be very hard to find creating spots that the fish visit because of the bait going in can be a very sucessful way of landing a few ... you dont need to feed loads and simple and cheap baits work ... a few cans of corn on each spot and handful of boilies over the top every 3 days is how i use to do it and ive had my fair share from canals.
