It's an odd one, I've fished it near the confluence with the Wye and I've fished it just upstream of Leominster.
Above Leominster it's a trout stream while at the confluence it holds just about anything with fins, with the exception perhaps of bream.
If I was prospecting it for the first time at this time of the year my chosen bait would be bread, either mash and flake/crust or feeder fed liquidised bread and punch or flake on the hook. Having said that it could be in the fields and lob and chop could be the answer.
