Tactics
The outer Dundrum Bay stretch toward Newcastle harbour is reliably productive for dab and flounder, with dogfish and whiting also on the cards and mackerel abundant in summer. Bass are a possibility when there's some sea running. The rock marks nearby fish well for pollack, wrasse and mackerel on spinners and float tactics, with the chance of a big conger on bottom-fished bait. Take care on rockier ground — wear a lifebelt, carry a phone, and don't wade out too far.
