I have caught them but they don’t seem to be as easy to catch there. Go to the peg with the bridge or the peg up from that and walk up to the little bridge. Cast out 6 hook with small to medium boilies try banofee I have had luck with that one
U can also catch barbel on Lego del mondo as I’ve caught a few using sweetcorn and and few on tigernuts
ive caught barbel on largo del mondo with Big red monster and esential cell and scb. they seen ok catching on there. i dont think there is many barbel in the canal.
I think I've caught them at the intersection between the big canal and the smaller one that enters, in the main channel with small hooks. I don't see many barbel though.
