Dolly Varden
Fish · Last reviewed 2026-10-09
A spotted char of North Pacific streams that runs to sea and back — once bountied in Alaska as a salmon killer, and now a fly and spinning fish in its own right.

Dolly Varden are char, not trout: fish of cold rivers and lakes around the North Pacific, many of which go to sea for the summer and come back to fresh water to spawn and to spend the winter.
They are easy to mistake for Arctic char, and the Alaska Department of Fish and Game gives the difference plainly. A Dolly Varden is generally greenish with many small spots, smaller than the pupil of its eye, a thick wrist to the tail and a tail that is only slightly forked. An Arctic char is bronze-yellow with fewer, larger spots, a slim wrist and a clearly forked tail. In Alaska the habit differs too: Dolly Varden spawn and mostly live in streams and rivers and may run to sea, while Arctic char generally complete their lives in lakes.
There are two forms in Alaska. The southern form matures at twelve to sixteen inches, rarely lives past eight years and reaches about twenty-eight inches and ten pounds. The northern form lives up to sixteen years and exceeds thirty inches and twenty pounds.
The history is worth knowing because it is still repeated. From 1921 to 1941 Alaska paid a bounty on Dolly Varden tails in the belief that the fish destroyed salmon. It ended when an examination of twenty thousand tails found more than half were coho salmon. The department's account now is that Dolly Varden mostly eat drifting salmon eggs that would not have hatched, and are more scavenger than predator.
Anglers meet them where the salmon are: sea-run fish follow salmon into rivers to feed on eggs.
Catching it

Where and when
Where Dolly Varden is documented
Places where public sources describe this species as fished, with how it is fished and how strongly the evidence supports it. This is not a range map and it is not a recommendation — it is what has been written down about a fishery rather than a record of any individual catch, and being listed is never permission to fish.

What these strengths mean
- Seasonal
- Well supported, and concentrated in part of the year rather than spread through it.
The fish
Identification
No photograph of Dolly Varden has passed identity review yet, so none is shown. A photograph is published only once somebody has checked the animal in it against the diagnostic features described on this page.
- Scientific name
- Salvelinus malma
- Family
- Salmonidae
- Water
- Freshwater, Saltwater, Moves between fresh and salt water
- Conservation status
- Least Concern
- Regions
- North America, East Asia, Arctic & Subarctic
- Greenish body with many small pale spots, each smaller than the pupil of the eye; the tail is only slightly forked and the wrist of the tail is thick.
- Sea-run adults are silvery with a faint green sheen and light orange spots, turning greenish-brown with dark orange to red spots once in fresh water.
- Spawning males are vivid: red, black and white bellies, black gill covers, orange and black fins with a bright white leading edge, and a strongly hooked lower jaw.
- Told from Arctic char by the spots and tail: Arctic char have fewer and larger spots, a slim tail wrist and a noticeably forked tail.
- Young fish in fresh water carry eight to twelve dark, irregular vertical bars along the side; dwarf resident forms may keep them as adults.
Size
- Typical
- 30–40 cm (12–16 in) at maturity for the southern form
- Large
- Up to about 71 cm and 4.5 kg (28 in, 10 lb) for the southern form
Exceptional: Over 76 cm and 9 kg (30 in, 20 lb) for the northern form; FishBase records a maximum of 127 cm and 18.3 kg
Lifecycle and reproduction
Slow-growing. In Alaska the southern form matures at five to six years and rarely lives longer than eight; the northern form matures at five to nine and lives up to sixteen. Dwarf freshwater residents mature at two to four years and only three to six inches. In their second to fourth year some young fish become smolts, lose their bars, turn silver and go to sea for the summer, returning to fresh water to spawn and overwinter.
Spawns in the autumn, between September and November, over gravel in small headwater streams or occasionally larger rivers. The female digs nests in the gravel and lays from 600 to 6,000 eggs, more in the northern form. Unlike Pacific salmon the adults can spawn more than once, though they rarely survive to do so more than three times, and may skip a year or two between.
Feeding and senses
Opportunistic carnivores. Juveniles feed on the stream bottom near the banks, mostly on insects and the larvae of mayflies and midges. Larger fish move to deeper pools and eddies and add crustaceans, salmon eggs and small fish. At sea they take amphipods and small fish such as sand lance and juvenile salmon, and sea-run fish follow salmon into rivers for their eggs, which is why egg imitations catch them.
The pages read do not describe how Dolly Varden detect food. They do describe feeding that is visual and positional in effect: juveniles holding near the bank to take insects, larger fish stationed in pools and eddies, and sea-run fish lying behind spawning salmon to intercept drifting eggs.
Through the year
Sea-run fish spend the summer feeding near shore in salt water and return to fresh water to spawn and winter. Most southern-form fish winter in lakes and the northern form in rivers or springs. In the Lower Cook Inlet streams fishing starts in July in the lower reaches and continues above them from August through October.
Distribution
North America: Arctic and Pacific drainages from lower Mackenzie River in Northwest Territories, Canada to Puget Sound and Quinault River in Washington, USA . Northwest Pacific: Korea to Bering Sea

Why anglers care
A sport fish across coastal Alaska that is often caught by anglers after something else and is worth fishing for itself. The Alaska Department of Fish and Game names fisheries for sea-run Dolly Varden from the Kodiak road system to the Kenai Peninsula, where they are among the most popular fish in the road-accessible streams. Fly and spinning tackle both work: egg imitations, smolt patterns and small streamers on the fly, spinners and small spoons otherwise.
Handling and returning
The pages read give no handling instructions specific to Dolly Varden. They do make the case for care: the fish grows slowly, matures late, and unlike a salmon can spawn again if it is returned in good condition.
