Brown trout
An introduced European salmonid holding in cool, oxygenated rivers, lakes and estuaries, feeding by sight on insects, baitfish and, in tidal reaches, whitebait and smelt. Wary and selective, it favours careful presentation over noise or numbers.

When to fish for it
Shading is when the fishing is good, not what the law allows. Seasons and limits are set per state — see rules and limits.
How it is fished
Nymphing under an indicator
A weighted nymph or two fished under a strike indicator, drifted drag-free through runs and pools; the indicator gets a gentle twitch every few seconds to search different depths.
When: year-round, the most consistent method across both islands
Spinning hardbodies and spoons
Small Rapala-style hardbodies, Toby spoons and Mepps-type blade spinners cast and retrieved across current, particularly effective when rivers are running fresh and full in spring.
When: spring, when rivers are up
Soft-baits on jig-heads for sea-run browns
75 mm soft-plastic minnows on 1/8 to 1/2 oz jig-heads (weight matched to current speed) worked through river-mouth and lower-river margins where sea-run browns ambush whitebait, smelt and bullies.
When: November to early March, river mouths at the right tide
Worm fishing on a ledger rig
A single garden or trout worm on a ledger rig with light split shot, cast just upstream of willow-lined banks or into slow pools and allowed to drift naturally along the bottom.
When: year-round, especially productive after rain has coloured the water

When they feed, and where
What makes a spot worth stopping at
Features you can pick off the water, and what the fish is doing there.
undercut banks and overhanging streamside vegetation
resident browns hold here through the day for cover and ambush on drifting food, only moving out to feed more openly at low light
approach from downstream and out of sight, drop a nymph or small streamer tight against the bank and let it drift or swing past the lie
riffle-to-pool current seams
fish hold in the sheltered slack beside the main current, nose upstream, picking off nymphs and drift food funnelled off the adjacent riffle
cast up and across into the seam, dead-drift a nymph or unweighted wet through the transition where fast water tips into the pool
river mouth gut and surf zone
shallow water at the river mouth concentrates baitfish and sea-run browns push in to ambush them, often boiling the surface as they feed
spin or swing a weighted smelt fly through the gut, working it back across the current on a pushing or falling tide
estuary channels and current edges
as the tide drops, sea-run fish retreat off the shallow flats into the deeper channels and hold along the current edge to intercept baitfish being drawn out
work a spinner, soft-bait or smelt fly along the edge of the channel, letting it swing with the current rather than retrieving straight back
first rapids above tidal influence
these obstacles slow and disorient upstream-running baitfish, creating a reliable ambush point where sea-run browns stack up
fish the pool immediately below and beside the rapid, drifting bait or swinging a lure through the slower water alongside the fast tongue
weed beds in lowland lakes
weed holds the snails, koura and damselfly/dragonfly nymphs that lake-resident browns cruise the edges hunting for
sight-fish or blind-cast along the weed edge with a nymph or small soft plastic, working it slowly past gaps and channels in the weed
What it eats, and what to tie on
Diet
Brown trout are opportunistic predators whose diet is dominated by aquatic insect larvae, drifting nymphs making up the bulk of daily feeding, but they switch onto terrestrial windfalls and baitfish whenever these become abundant. Lake fish work weed beds for snails, koura and damselfly/dragonfly nymphs, while sea-run fish in Southland and similar fisheries follow whitebait and smelt runs into estuaries.
Prey: mayfly nymphs, caddis larvae, stonefly nymphs, cicadas, beetles, smelt, bullies, whitebait, koura/crayfish, snails, damselfly and dragonfly nymphs, mice
Bait
- live or dead smelt — drifted or slow-trolled around river mouths and estuary channels for sea-run fish
- bullies — drifted near the bottom in river mouth pools and channels
Lures and flies, by type
Length and weight are the point — match them to the cast weight in the outfit table.
| Type | Length | Weight | Depth | Colour | How it is worked |
|---|---|---|---|---|---|
| Hard bodies | |||||
| revolving-blade spinner | 40-60 mm | 7-14 g | sub-surface to about 1 m | silver/black in clear water, gold or fire-tiger in discoloured water | Celta- and Vibrax-style blades and Tasmanian Devil wobblers are standard river and river-mouth spinning lures; yellow-grey patterns favoured at river mouths after dark |
| shallow-diving minnow | 40-70 mm | 3-5 g | 0.3-1 m | brown trout pattern or bait-fish silver | a light setup casting small 3-5 g lures is standard for stream and small-river work |
| trolled/casting minnow | 80-130 mm | 8-15 g | 1-3 m | baitfish silver or brown trout pattern | Rapala floating and countdown divers up to 13 cm are used for casting and trolling larger highland lakes |
| Soft plastics | |||||
| small baitfish paddle-tail | 50-80 mm | 3-7 g jig head | surface to 1.5 m | translucent/natural in clear water, brighter in dirty water | increasingly used in place of flashy hardbodies at river mouths and estuary channels |

Tuesday after the June long weekend to the last Friday prior to the start of the October long weekend
Tuesday after the June long weekend to the last Friday prior to the start of the October long weekend (general trout streams). For 2026 DPIRD states the closure commences Tuesday 9 June 2026 and waters reopen from the start of the October long weekend, Saturday 3 October 2026.
Detail
Bag and possession limits are combined across trout and salmon species (Atlantic Salmon, Brown, Rainbow, Brook). Different limits apply in artificial fly and lure only waters (25 cm, bag 2, possession 4) and in trout spawning streams from 1 May to the end of the King's Birthday long weekend (50 cm, bag 1, possession 2) — see exceptions. The stream closure does not apply to trout dams. Closure dates for artificial fly and lure streams and trout spawning streams run 'Tuesday after the June long weekend until midnight 30 April the following year'.

Detail
Brown trout is a "salmon" (family Salmonidae) under the Inland Fisheries Act 1995, so reg 15(5) (300 mm) and reg 17(2)(b) — "a person must not take, on any one day from inland waters or excepted waters, more than a total of 12 salmon" — apply. The bag limit of 12 is a COMBINED salmonid limit, not per-species. Many individual waters set stricter size/bag limits (see exceptions and the A to Z of Waters). Measured "from the tip of the snout to the fork of the tail". Reg 17(8) sets an explicit possession limit only for eels (24); no equivalent salmonid possession limit was found in the regulations.

10 named waters that differ from its authority's general rule
- Trout spawning streams — Thredbo River and Eucumbene River (and tributaries) — From 1 May to the end of the King's Birthday long weekend these waters run under separate spawning-stream rules: 50 cm minimum size, daily bag limit 1, possession limit 2, artificial fly or lure only (no handlines, no dough-based baits).
- Artificial fly and lure only waters (incl. blue ribbon streams, catch-and-release streams, trophy trout dams, trout spawning streams) — Notified trout waters split into two classes; in artificial fly and lure only waters the trout daily bag limit is 2 and possession limit 4 (instead of 5 and 10), and bait is prohibited. The Eucumbene and Thredbo Rivers sit in this class from the Saturday of the October long weekend to 30 April inclusive.
- Trout dams vs trout streams — The annual winter closure applies to general trout streams, artificial fly and lure streams and trout spawning streams — trout dams such as Lake Jindabyne and Eucumbene Dam stay open through the closure.
- Lake Otamangakau — Slot-style limit found nowhere else in the district: "two trout per day regardless of species", no minimum size and a maximum takeable size of 55 cm; DOC's where-to-fish page gives the season as "1 October to 31 May (summer closures weather dependent)" while DOC's 2022 change notice describes a 1 September start — the two DOC pages disagree, so the season dates here are not settled.
- Hangatahua (Stony) River — Bag is 2 rainbow trout and zero brown trout.
- Yingina / Great Lake — "Brown trout min. size 300, Rainbow trout min. size 400 with max of 3 rainbow trout", bag limit 12; Tods Corner and the main lake are open year-round and Tods Corner is artificials-only, while Canal Bay opens only "28/11/2026 - 28/3/2027" and is artificials-only.
- Designated rainbow trout waters (incl. lakes Mackintosh and Rosebery) — A separate season: "Opening of designated rainbow trout waters" 3 October 2026 and "Closure of designated rainbow trout waters, lakes Mackintosh and Rosebery" 30 May 2027, versus 1 August 2026 – 2 May 2027 for most waters.
- Bream fishing areas (e.g. Derwent, Huon, Coal and Arthur rivers) — Inside a bream fishing area "a freshwater angling licence is required for trout and seasons may apply. Bream and marine species can be taken without a freshwater angling licence with up to two rods, all year round."
- Trout/salmon closed season - tailrace sections (Goulburn, Kiewa, Mitta Mitta, Tanjil rivers) — These tailrace sections are closed to ALL hook and line fishing during the trout and salmon closed season regardless of target species, and a hook and line may not be possessed within 20 m of them.
- Lake Toolondo and Hepburn Lagoon — Run under their own salmonid rules: Lake Toolondo 45 cm minimum brown trout / 30 cm minimum rainbow trout, Hepburn Lagoon 45 cm minimum brown and rainbow trout, both with a bag limit of 3 salmonids per day and no closed season.

▶Common questions
What is the best time of year to catch brown trout?
Spring through autumn, once rivers open after the winter spawning closure. In New Zealand most brown trout rivers open on 1 October and fish are in prime condition through summer into April, while in Tasmania the season typically runs August to May with September–October and the October–March mayfly-hatch stretch producing the best sport. Exact opening and closing dates vary by region and water, so check the local rules before you go.
How big do brown trout get?
Most brown trout landed by anglers weigh 1–2kg, but resident river fish can reach 800mm and 5kg. Sea-run browns that feed on mullet, sprats and smelt in estuaries grow much larger again, with fish up to 7kg or more recorded and anything over 5kg considered a trophy.
How do you tell a brown trout apart from a rainbow trout?
Look at the tail: rainbow trout carry dark spots on the caudal (tail) fin, while brown trout almost never do. Browns also show red spots alongside their black spotting, especially in river fish, and have noticeably larger pectoral fins than rainbows. Colour is a less reliable guide, since it shifts with habitat: river browns run golden-brown while lake fish are duller and more silver.
Do you need a licence to fish for brown trout?
Yes. In New Zealand every angler, including children, needs a Fish & Game licence to fish for trout anywhere outside the separately-managed Taupō district. In Australia a freshwater fishing licence is likewise required in most states. Bag limits, size limits and licence costs all differ by region, so check the rules for the specific water before you fish.
Are brown trout good to eat?
Yes, though flavour depends heavily on size and diet. Smaller fish in the 1–2kg range have firmer flesh and a milder taste than large, old trout, and fish that have been feeding on crabs and other crustaceans in estuaries or river mouths tend to have deep-red, well-flavoured flesh. As with any wild-caught fish, only keep trout from clean water you trust.
Are brown trout hard to catch?
Brown trout have a reputation as the wariest of the trout species, quick to spook in bright, clear, low water and sensitive to noise and shadow on the bank. A quiet approach, a drab profile and an accurate first cast matter more than fancy gear, and a basic 6-weight fly outfit with a floating line is enough to get started on most AU/NZ trout water.
Fishing for brown trout on water you don't know?
A local guide fishes it every week. The directory lists them by region.
