With a mild autumn there's still lots of boat activity on the canal leading to poor water clarity. I've done well with dark coloured creature baits, including a great little session on the Hart Curly, seen here.
Once you've found them Lesser Weever are pretty easy to catch. Aggressive little things. They very much like movement and will come way off the bottom to hit a moving lure. Here, a natural coloured Knight Worm. Please be careful. They're highly venomous.
