Fruit plants

in Fruit & veg
Hi all I have 2 fruit plants, 1 which is either a blueberry, black current ( I can't remember to be honest) and 1 which is a wine Berry ( I'm definate about that Identification ) . I've bought them around August / Sept 20 and they produced some fruit last simmer, nothing to write home about. So my question is about pruning I don't understand what I'm supposed to do. From what I've read there should be old wood and new wood, but it looks all the same to me. On the blueberry blackcurrant there are buds growing everywhere, I assume that is a good thing. On the wine Berry, just a few buds here and there.

WINEBERRY

Should I be doing something.
Any advice will be appreciated

They get to about 5ft high and about the same width.
No need to prune it atm
Once there are lots of stems, prune out about 1/3 of the oldest stems in the autumn after picking the berries to leave about 8-10 stems.
I imagine the Wineberry will grow much bigger
