"but could,nt find anyone fishing"
Welcome to Christchurch harbour.
I spent quite a bit of time on there about 4 or 5 years ago and only ever saw one other angler and he was fly fishing for mullet.
If you go round from 2 rivers and carry on round the corner past the moored boats there is some fantastic fishing on the float for mixed bags.
Take your chesties and get in the river and trot down off the rod tip with maggot, feeding every trot down.
I've had 40 to 50lb bags of roach, dace, skimmers, chub, bass and mullet.
I also took a 5lb thin lipped on the tip down there.
From the ferry side, if you fish around the park area, then close to all the moored boats is very good for dace, especially if the river is up and coloured.
Above the bridge into perch pool and you will sometimes see the occasional large carp,
maybe,
I think,
possibly,
if you get my drift ;o)
