Identification
Long silver-flanked sub-Arctic predator built for cruising open water and hammering baitfish schools. Long determined runs and spectacular aerial leaps earned it the nickname 'tarpon of the north'. Northern Yukon and Alaskan stocks grow heaviest.
- Bright silver flanks with a greenish-blue back and white belly
- Large reflective scales — much larger than other northern salmonids
- Wide terminal mouth with the lower jaw projecting slightly past the upper
- Deeply forked tail
- Small adipose fin between back fin and tail

Behaviour
An aggressive open-water piscivore — adults feed almost exclusively on schooling baitfish. Forms loose roving aggregations that ram-feed through bait pods, striking fast-moving lures with explosive aerial takes. Sea-run and lake-migrating populations winter in deep estuaries and deltas, then push hundreds of kilometres upriver to spawn. Peak feeding 4-15°C (39-59°F); bite stays strong even near-freezing. Dawn and last-light dominate; overcast extends the feed.
Diet: Baitfish, Cisco, Whitefish, Smelt, Sand Lance
How it's caught
Line Fishing
Spinning
The defining method. Cast medium-to-large spoons (Pixie, Krocodile, Daredevle 20-40g) and big inline spinners across river mouths, confluences, and deep migration pools. Fast cross-current retrieves trigger explosive aerial strikes. Silver and chrome finishes outproduce everything when fish are keyed on whitefish and cisco. Long casts cover migration lanes efficiently.
Trolling
Troll big spoons and dive plugs through deep delta basins and lake shelves where summer-feeding fish hold. Speeds 5-9kph match strike speed on these aggressive piscivores. Downriggers reach the 5-20m holding zone. Stack multiple rods to cover the column until active fish are located.
Jigging
Vertical jig heavy spoons (20-40g Buzz Bombs, big tube jigs) over deep pool structure and lake drop-offs once fish are located by sonar. Aggressive snap-jigging draws strikes from suspended fish. Most productive on staging fish at confluences during pre-spawn migrations.
Fly Fishing
Streamer
Strip large baitfish-imitating streamers (8-15cm Clousers, articulated patterns, smolt imitations) through river-mouth seams and deep pool tailouts during the late-summer migration. Heavy sink-tip lines get the fly into the strike zone. Fast aggressive retrieves matter — these fish chase down and crush rather than sip.
