2 Derwent River

Piersons Point - Iron Pot mark the lower limit of the Derwent Estuary and the transition to Storm Bay and the Tasman Sea. A good boat ramp at Tinderbox services this area and you should be aware of a Marine Reserve here that runs between Tinderbox and Bruny Island. Please refer here for relevant information, access and restrictions. Outside this there is excellent fishing for sand and tiger flathead, Australian salmon, couta (barracouta), plus longfin pike and occasionally good runs of squid. Warehou usually appear in the summer - autumn period and are known locally as snotties, or snotty trevally.

Ralphs Bay is a large enclosed bay on the eastern side of the estuary noted for large flathead. Whiting, flounder, mullet and Australian salmon are also caught. Atlantic salmon are sometimes caught near the mouth.
Tranmere - Tasman Bridge. Punchs Reef - just off Tranmere is a popular spot for cod, morwong, trevally, garfish and Australian Salmon. Large trevally are targeted from the shore and boat in this area. Try Kangaroo Bluff at Bellerive and also the Howrah area.
Sandy Bay is easily fished from both shore and boat and can be very productive. The target is generally flathead but catches of garfish, morwong, mullet and Australian salmon are common.
Tasman Bridge - Bowen Bridge not a lot of action, but it is a good bream area. Try Lindisfarne Bay, Prince of Wales Bay and Bedlam Walls area. 
Just north of the Tasman Bridge cod, flathead, Australian salmon and trevally are also caught as are sea run trout from August through to October. Barracouta are often targeted beneath both sides of the bridge - as are Australian salmon and sea trout. 
Bowen Bridge - Bridgewater. Otago Bay is upstream of the Bowen Bridge on the eastern shore. Many species are caught in this vicinity including a few 'stud" bream every year to 2 kg+. Smaller specimens are quite common. Small bib lures are popular as is bait and fly. Anglers chase both sea-run and resident trout in this area all year round - often with great results and trout to 5 kg are sometimes caught. All methods can be used to take these trout from trolling to bait, lure or fly fishing - both from boat or shore. Many other species are also taken in this area including flathead, pike, cod, mackerel, Australian salmon and the occasional escaped Atlantic salmon. 
Above Bridgewater is mostly a trout and bream fishery. After Christmas the bream fishing heats up in this section. Anywhere that there is access to the water, bream can be caught. The shore based angler enjoys the best fishing and there are plenty of access points. Prawns, pretty fish and sand worms are the best bait.
