Good post and good luck breaking you PB pike mate.
@peace frog Regarding the Dane, as DD says it's a perfect river to learn on. However, for a small river it's a pressurised water and we're also fast approaching the first frost of the year which will knock them off the feed till they get used to the temperature drop. So, if you have time I'd get there sooner than later. I've not fished the Dane for several years now, probably 15 years. I used to fish Cotton Hall farm and Cotton farm. I think Bay Malton now have both stretches, but not sure. I fished the farm more upstream of the M6 J18.
Make sure your line is 12lb mainline and I'd go 10lb flourocarbon hooklength. May seem crude but barbel are very powerful fish built to fight hard! I like E.S.P Ghost Soft and Fox Illusion best, although there are other premium lines. Don't scrimp on buying cheap line or hooks because it could mean the difference between losing a fish of a lifetime or landing it. I remember one of the last sessions I fished in there I had brand new 8lb Maxima straight through, and when my rod arched round, either barbel or carp snapped it like cotton!
Hooks are also very important. Best quality hooks are lightweight forged steel Matt black with razor sharp points. I like Korum S5 and Xpert power hooks. Drennan Specialist Barbel, and Kodex Genomic MGP microbarbed. There are other brands I use but those I rooted out of my tackle box just now. Don't use shiny hooks, especially in bright sun and shallow water. I used to use Kamasan Animal hooks but they are too bright and shiny and unless you're fishing in deep dark water wily fish will back off. The Dane isn't deep or dark enough to use them even though they are strong sharp and reliable.
Good swims on there are often the ones with signs of bank wear and litter, unfortunately: /
Try and chose a swim on a deeper glide. At least 8m upstream of it if your fishing same bank. Fishing the shallow bank of a deep bend opposite or slightly upstream of is ideal, a gravel bottom and light streamer weed better still. And when the water temperature drops you want to try and locate a deep hole, especially in winter months.
As for bait, barbel big chub and carp have seen it all. Various boilies pellets and meat and if you use those baits you're limiting your species mostly to Barbel Chub and the occasional carp. So, I'd be tempted to fish the humble maggot which is often overlooked nowadays for specimen fish. The advantage of maggots is that you can catch perch roach dace and the occasional bream and grayling in the Dane. You may get played with nuicance Minnows at first but if you cast regularly you will either feed them off or bigger fish will nose them out. River fishing maggots is often a pecking order and you will often get left with mostly chub and barbel competing for food. Chub have a voracious appetite and a 3lb chub can probably snaffle had a pint of maggots if allowed to! Many years ago my mate had a 4 ounce chublet in his tropical tank and we fed it one maggot at a time. It at 29 maggots before it couldn't eat anymore. It was still trying to eat more but was comical watching maggots come out off it's God as it went for more!
I'd start off with half a dozen casts of medium maggot feeder with no hooklength on. Cast as accurately as you can and be mindful of any snags you get stuck on, sunken debris, tree branches etc. Fish love the sanctuary of snags but your tackle doesn't so don't cast to a hidden snag if you get snagged twice in same spot.
Start off with a simple 12-18" tail on a running feeder. Thread eye of feeder swivel through your reel line. Thread a rubber 6ml bead on and attach a medium to large Drennan quick change bead on. These are a brilliant invention in that you can swap hooklengths fast.
Once you get the fish competing for food you can adjust to suit. Barbel are often downstream of smaller fish competing for your feeder bait waiting for loose bait drifting past their nose. If you have fed for an hour or two when you think there are barbel present I think it may be worth lengthening your tail to as much as as 4 foot. On bigger deeper rivers like the Trent it can pay dividends with a 6 foot tail!
Don't forget to tie your knots well and wet knot in your mouth just before you pull tight or you may get a pigtail. There's a lot more to barbel fishing than what I and DD have said but if you follow advice given you'll be on the right track to success. But river fishing is often futile, so be prepared to be patient and as quiet and stealth-like as possible. You will eventually learn rivercraft but it takes time. Steady flowing water is often deep, but fast paced water is usually shallow, then there's creases in the river, eddy's and back eddy's. Don't worry to much about it for now though. Concentrate on the basics first.
Good luck and tight lines: )
