Hook, line, that's all you need mate. The bread is the right way to go, but you need to get the fish feeding first, go to the area on the landward side of the gangways and use a berley of bread, tuna oil and water to get them feeding closer to the surface, then use bread (not too big a piece or they'll only nip at it) tied to a smallish suicide hook, about a size 2 or 4, cast into the feeding fish, give a bit of free line and then hold on! I've caught bream over 40cm using this method off the jetty, as well as a few little blue puller and numerous bloody butter bream. It takes a bit of getting used to and is very hard going in the wind, but you should definitely pull a few fish. Good luck and PM me if you need any more advice about the area, I've been going there for years and it is a great place to fish. Just be repsonsible in how many fish you keep.
