Trout Cod
Trout cod are a native Murray-Darling predator that once ranged across the southern basin but have been reduced to a handful of wild strongholds and a single legal recreational fishery — Lakes Sambell and Kerferd near Beechworth, Victoria.
Catching one anywhere else means you've stumbled onto something rare and must release it immediately. That combination of scarcity, conservation significance, and genuine fighting ability makes every encounter count.
Scientific Name: Maccullochella macquariensis
Also known as Bluenose cod, bluenose
- Blue-grey to brownish body with irregular spots and dashes — distinct from the green-olive mosaic pattern of Murray cod; belly pale to white.
- A clear horizontal dark stripe runs from the snout through the eye to the gill cover — the single most reliable field mark for separating it from Murray cod.
- Upper jaw overhangs the lower (protruding snout), unlike the shorter, blunter snout of Murray cod; fins grey to dark grey with broad white margins.
- Common fish run 40–50 cm and 1.5–3 kg; larger individuals exist but are rarely encountered given the species' depleted state.
What to know
Habitat Distribution
- Endemic to the Murray-Darling Basin; once widespread through southern tributaries but now reduced to scattered wild localities and stocked impoundments.
- Last confirmed self-sustaining wild populations are in the Murray River between Yarrawonga and Barmah, and in Seven Creeks; reintroduction programs have re-established fish in the Goulburn, Ovens, and Murrumbidgee Rivers.
- The only legal recreational fishery is Lakes Sambell and Lake Kerferd near Beechworth in north-east Victoria, stocked through a captive-breeding program funded by fishing licence revenue.
- Prefers cool to moderate river reaches with rocky structure, snags, and clear water — the same habitat that once supported healthy populations before European land-use change.
Key Locations
- Lakes Sambell and Lake Kerferd, Beechworth, north-east Victoria — Australia's only open recreational trout cod fishery, maintained by stocking.
- Murray River between Yarrawonga and Barmah — one of the last stretches holding a self-sustaining wild population, though fishing for them here is not permitted.
- Seven Creeks, Victoria — another known wild stronghold; protected, not a fishing destination but significant for the species' survival.
- Goulburn, Ovens, and Murrumbidgee Rivers — reintroduction sites where captive-bred fish have been released; populations are rebuilding but these fish remain fully protected.
Specific Spots
- Rocky ledges, submerged boulders, and large woody debris — trout cod hold tight to hard structure, using it as cover between feeding forays.
- Current breaks behind large rocks or fallen timber, where fish can sit out of the main flow and intercept prey drifting past.
- Deeper pools adjacent to fast runs; trout cod move into shallower water to feed under low-light conditions but retreat to depth during bright midday periods.
- In the stocked lakes at Beechworth, work the edges of weed beds and any submerged structure — fish concentrate wherever cover and food intersect.
Trout Cod FAQ
Answers from onWater's species guide.
What are the best lures and bait for Trout Cod?
Soft-plastic paddle-tails and crayfish imitations worked slowly along the bottom near structure are a reliable starting point, match the retrieve to the fish's mood, slower in cold water.
When is the best time to fish for Trout Cod?
No closed season applies at the Beechworth lakes fishery, so fishing is permitted year-round. Warmer months (spring through autumn) generally see more active fish as water temperatures rise and feeding activity increases.
How do you catch Trout Cod?
Virtually all legal trout cod fishing in Australia happens at Lakes Sambell and Lake Kerferd near Beechworth, where anglers fish from the bank or small boats, working soft plastics and hard-bodied lures around structure and weed edges.
What do Trout Cod eat?
Feeds on smaller fish, crayfish, and large aquatic invertebrates; in rivers, yabbies (freshwater crayfish) are a key food source, soft-plastic lures and crayfish-pattern flies both draw strikes for this reason.
Where do Trout Cod live?
Endemic to the Murray-Darling Basin; once widespread through southern tributaries but now reduced to scattered wild localities and stocked impoundments.
