hi mate , sorry about the huge photo that's all i could find , winter can be quite challenging and some days impossible to get a bite in the harbour , you really have to try really hard to bring them on the bite , no matter what your targeting that is , if you are after baitfish and the only thing available is on the bottom you must use the paternoster rig with one of these burley cages and some weight in it, stick a bit of sardine and prawn heads with some old bread , the sardine and prawn is for the oil and the smell, the bread is something that will bring them around because it will break up a bit , use 3 hooks 12 or smaller for the smallest baitfish that are there and one size 8 for the leaterjackets if you are trying to catch some of those also , Dorry will take a big bait but the best bait are the smallest baitfish you can find, in order to keep the bait from snagging somewhere you have to use heavy main lines with a heavy sinker that stops them from swimming all over the place , also use a meter trace no more then 20lb so that is the only thing that will break off is the trace if it does get caught somewhere , when you lower the baitfish to the bottom make sure that you sinker is about a metre and a half of the bottom this way it does not get snagged, some wharfs will work better then others for Dorry , i find that they dont like hunting in strong currents , so places like the piers will work best take a kid with you and set up 6 lines/rods for them , this way you can increase your chance of finding one or two, keep on trying and you will find them
