Spermwhale,
Change of light and during the night are my preferred and more successful times to fish the harbour,most of my spots are incoming but I do have outgoing spots too.Wind with the tide usually dictates where I’ll be sitting.
I prefer to fish on the edges of channels,2 hrs either side of the tide seem to produce but I tend to fish right through the run in.
To start I use a strayine rig,slowly adding weight as the tide picks up or even cast out my line then adding the weight to have my trace wafting around out the back.Then taking weight off again as the tide slows towards slack tide and once again straylining.
I berly the whole time,frozen is ok but cloudy, I prefer a chunky Berly mashed while I’m fishing seems to work better,even cubing(small cubes)bits of bait is the go.
As you can see fishing in the harbour keeps you busy the whole time.You can’t just put a bait out and sit back if you want to be successful.
Full moon and any wind with a bit of southerly in it can make it a bit less productive.But you’ll never catch a fish without being out there trying.
Take a run around the harbour on a spring low tide you will learn a lot about where fish will feed and travel.
There’s some good fishing to be had in the harbour if you put in the time.From now right thru till about June.
Just remember it’s fishing not gathering so don’t be put off by a fishless trip, it happens to us all.Even if some tell you otherwise.
Good luck
