Fishing Unalaska (Dutch Harbor), AK: The Local Water

The Inlet & Bar

Priest Rock, a 204-foot pinnacle off the north side of Cape Kalekta, is one of the most important landmarks in making Unalaska. The area about the cape's extremity is foul and marked by kelp, and a dangerous ledge that uncovers 1 foot, usually marked by breakers, lies nearly 0.4 mile north of it. Iliuliuk Bay opens between Ulakta Head and Second Priest Rock, and its entrance is marked by a lighted bell buoy.

Local Waters

North of Spithead a covered ridge runs across Iliuliuk Bay with at least 6 to 7 fathoms near the middle, and kelp has been seen on it in about midchannel; south of the ridge depths increase to 18 fathoms. There is anchorage almost anywhere in the bay, the usual spot being at the head in 14 to 16 fathoms over mud, where even north winds do not bring much sea.

Reefs, Structure & Marks

Ulakta Head, the north end of Amaknak Island, is about 900 feet high with a flat top that breaks off abruptly to sloping sides — in clear weather one of the best landmarks for fixing the position of Unalaska Bay. A reef runs 0.1 mile off its northwest point, marked by Needle Rock. Mount Ballyhoo, 1,589 feet, dominates Amaknak Island, and Princess Head on the east side of the bay is a wall-like formation with a level top 214 feet high.

Harbors, Launches & Access

Spithead is the end of the long, low sandspit that forms the east side of Dutch Harbor, carrying a light 38 feet above the water on its south end. Shoal water under 6 fathoms, marked prominently by kelp, extends 0.3 mile into Iliuliuk Bay from the middle of the spit, and Rocky Point has a kelp-marked reef reaching 400 yards toward Spithead with a lighted buoy on its outer limit. Unexploded ordnance has been observed in nearshore waters of southeast Iliuliuk Bay adjacent to the Dutch Harbor Landfill.

Always check local regulations — seasons, size, and bag limits vary by state and species, and change year to year. When in doubt, release.

Bays, Lagoons & Beaches

Tidewater and the lagoons behind the beaches — all five salmon staging before they run, and sea-run Dolly Varden working the current seams behind them

Nearshore Reefs & Kelp

Rocky shoreline, kelp and the shallow shelf inside the passes — halibut on the sand edges, cod and rockfish over hard bottom, greenling right in the weed

Open Water & Banks

The shelf and slope beyond the islands — trophy halibut flats, cod banks, and the deep edges where yelloweye and sablefish live

Inshore

  • Sockeye Salmon (Oncorhynchus nerka) fish identification illustration
    Sockeye Salmon — Bristol Bay's run peaks late June into July; short-line a weighted sparse fly or bare hook through the travel lane along the bank, where reds move in dense pulses.GearSockeye fliesBead and yarn rigsDrift fishing rod
    How to ID
    • No spots on back or tail
    • Bright silver body at sea, greenish-blue back; prominent glassy eye
    • Many long, fine, serrated and closely spaced gill rakers on the first arch (over 30–40)
    • Spawners turn bright red with a green head

    Typical: 22–28 in, 4–8 lb

    Tell it apart: Spotless body plus numerous long, fine, closely set gill rakers (count them on the first arch — far more than chum's short, sparse rakers) confirm a sockeye.

    Easily confused with: Chum Salmon, Pink Salmon, Coho / Silver Salmon

  • Chinook / King Salmon (Oncorhynchus tshawytscha) fish identification illustration
    Chinook / King Salmon — Runs June-July on the Nushagak and the Peninsula rivers; back-troll plugs and drift bobber-and-yarn through holding water, or troll cut-plug herring in the salt.GearCut-plug herring rigSalmon plugsSalmon mooching rod
    How to ID
    • Black gums/gumline at base of teeth on lower jaw (mouth interior also dark)
    • Irregular black spots on the back AND on BOTH lobes of the tail
    • Silver body, blue-green back; large, robust, deep-bodied
    • Spots present on entire caudal fin, not just the upper lobe

    Typical: 24–36 in, 15–30 lb

    Tell it apart: Black gumline along the lower jaw PLUS spots covering both tail lobes separate a king from a coho's pale/white gums and upper-lobe-only tail spotting. Don't rely on size or fin-ray counts alone.

    Easily confused with: Coho / Silver Salmon

  • Chum Salmon (Oncorhynchus keta) fish identification illustration
    Chum Salmon — Thick July-August in tidewater and the lower rivers; swing chartreuse and green spoons, spinners and yarn flies for fish that hit swung hardware hard.GearBright casting spoonsInline spinnersYarn flies
    How to ID
    • No distinct spots on back or tail
    • Silver at sea; spawners show purple/green vertical 'calico' bars
    • Whitish tips on anal and pelvic fins
    • Narrow caudal peduncle (thin tail base)
    • Large, often white-rimmed pupil/eye

    Typical: 24–28 in, 8–15 lb

    Tell it apart: A spotless back and tail combined with a thin caudal peduncle and white-tipped anal/pelvic fins separate chum from spotted pinks/coho and from spotless sockeye (use gill-raker count to split chum from sockeye).

    Easily confused with: Sockeye Salmon, Pink Salmon, Coho / Silver Salmon

  • Pink Salmon (Oncorhynchus gorbuscha) fish identification illustration
    Pink Salmon — Heavy on even years July-August; cast small pink spoons and jigs into the schools stacked at river mouths and along tide rips.GearPink casting spoonsSmall pink jigsLight salmon combo
    How to ID
    • Large oval/oblong black blotches over the entire tail AND on the back
    • Very small scales (smallest of any Pacific salmon)
    • Bright silver at sea; smallest, most slender Pacific salmon
    • Spawning males develop a pronounced humped back

    Typical: 18–25 in, 3–5 lb

    Tell it apart: Big oval spots covering the WHOLE tail plus the tiniest scales of any salmon clinch a pink; coho spot only the upper lobe and chum has no real spots.

    Easily confused with: Coho / Silver Salmon, Chum Salmon

  • Coho / Silver Salmon (Oncorhynchus kisutch) fish identification illustration
    Coho / Silver Salmon — Best August into October, later than Southeast; cast bright spoons and spinners across tidewater current and swing them, or troll herring outside the lagoons.GearCasting spoonsInline spinnersSalmon spinning combo
    How to ID
    • Black mouth interior but WHITE/gray gums at base of teeth on lower jaw
    • Spots on back and on the UPPER tail lobe only (lower lobe usually clean)
    • Bright silver sides, blue back; broad caudal peduncle
    • Moderately forked tail

    Typical: 24–30 in, 8–12 lb

    Tell it apart: White/gray gums (against the black mouth) with spots confined to the upper tail lobe mark a coho versus the king's black gumline and fully spotted tail.

    Easily confused with: Chinook / King Salmon

  • Dolly Varden (Salvelinus malma) fish identification illustration
    Dolly Varden — Sea-run dollies follow the salmon in from June; small bright spoons, beads and egg patterns along current seams and behind spawning fish.GearSmall casting spoonsBead rigsLight spinning combo
    How to ID
    • Light-colored spots on a darker greenish body — the inverse of a trout
    • Many small spots, each SMALLER than the pupil of the eye
    • Relatively thick caudal peduncle and only a slightly forked tail
    • Spawning males develop a distinct kype, red-black-and-white bellies, black gill covers and bright orange to red spots

    Typical: 12–24 in

    Tell it apart: Spots smaller than the eye's pupil, a thick caudal peduncle and a barely forked tail separate a Dolly Varden from an Arctic char, which has fewer and larger spots on a slimmer peduncle behind a deeply forked tail.

Nearshore

  • Pacific Halibut (Hippoglossus stenolepis) fish identification illustration
    Pacific Halibut — Prime May-September; drift sand and gravel edges in 120-350 ft with heavy jigs, or anchor with large circle hooks baited with herring over the flats.GearHeavy circle hooksLarge leadhead jigsHalibut rod combo

    • Both eyes on the right (dark, upper) side; right-eyed flatfish
    • Large diamond/oval flat body, lies on its side
    • Dark brown/mottled top side, white underside
    • Large mouth reaching to the eye; strongly forked (lunate) tail
    • Lateral line arches high over the pectoral fin

    Typical: 30–45 in, 12–40 lb

    Tell it apart: A large right-eyed flatfish with a strongly forked tail and white underside is a halibut, not an arrowtooth flounder (slimmer, large-mouthed, nearly straight tail) — confirm the forked tail and arched lateral line.

  • Pacific Cod (Gadus macrocephalus) fish identification illustration
    Pacific Cod — The dependable fallback nearly year-round; work a plain leadhead with a big soft tail slowly over hard bottom in 100-300 ft.GearHeavy bottom jigsShrimp fly bait rigsBottomfish rod combo
    How to ID
    • Single long chin barbel (whisker) at least as long as eye diameter
    • Three separate dorsal fins and two anal fins
    • Brown/gray mottled body, pale belly
    • Pale, curved lateral line
    • Rounded/square tail, blunt snout

    Typical: 20–32 in, 5–15 lb

    Tell it apart: The single fleshy chin barbel and three separate dorsal fins are unique among Alaska bottomfish and immediately separate cod from the barbel-less, single-dorsal lingcod.

  • Black/Dusky Rockfish (Sebastes melanops) fish identification illustration
    Black/Dusky Rockfish — Sits up off the rock around nearshore pinnacles; cast and jig swimbaits and shrimp flies near the surface and through the mid-column.GearSoft swimbaitsShrimp fly rigsMedium jigging combo
    How to ID
    • Dark gray to black (black rockfish) or olive/brown-gray (dusky)
    • Spiny dorsal fin: black rockfish ~13 spines, dusky ~14
    • Black rockfish: dark spots/blotches on the spiny dorsal fin; dusky plainer
    • Black rockfish anal fin trailing edge ROUNDED; dusky SLANTED/straight
    • Heavy-bodied schooling rockfishes; large mouth

    Typical: 14–20 in, 2–5 lb

    Tell it apart: Both are dark schooling rockfish; the trailing edge of the anal fin separates them — ROUNDED in black rockfish, SLANTED/straight in dusky.

    Easily confused with: Yelloweye Rockfish

  • Kelp Greenling (Hexagrammos decagrammus) fish identification illustration
    Kelp Greenling — Right in the kelp and over shallow rock inside 150 ft; small baited hooks, shrimp flies and little jigs fished close to the weed take them readily.GearSmall shrimp fliesLight metal jigsLight saltwater combo
    How to ID
    • Five lateral lines along each side
    • Two fleshy cirri — one above the eye, one small one midway between eye and dorsal fin
    • Females freckled all over with small reddish-brown to golden spots on gray-brown, fins mostly yellowish orange
    • Males gray to brownish olive with irregular BLUE spots over the front half to two-thirds, each ringed by small reddish-brown spots
    • Often an eye-like ocellus at the rear of the soft dorsal, just ahead of the tail; mouth yellowish inside

    Tell it apart: Five lateral lines plus a pair of fleshy cirri over the eye identify a greenling; the sexes look like different fish — blue spots forward on males, rusty-gold freckling all over on females.

Offshore

  • Yelloweye Rockfish (Sebastes ruberrimus) fish identification illustration
    Yelloweye Rockfish — Deep on the same structure as the blacks; drop heavy jigs and bait rigs to the bottom and carry a descending device to release fish unharmed.GearHeavy rockfish jigsShrimp fly rigsDescending device
    How to ID
    • Bright orange to orange-red body (adults)
    • Brilliant yellow eyes
    • Raspy/rough bony ridges over and behind the eyes
    • Juveniles have one or two pale/white horizontal stripes along the body
    • Heavy body, strong dorsal and anal fin spines

    Typical: 20–28 in, 5–12 lb

    Tell it apart: Orange-red body with vivid yellow eyes and rough bony ridges over the eyes positively IDs a yelloweye (locally 'red snapper') — its bright color alone separates it from the dark black/dusky rockfishes.

    Easily confused with: Black/Dusky Rockfish

  • Sablefish (Anoplopoma fimbria) fish identification illustration
    Sablefish — Lives deep on the slope below about 650 ft; heavy weighted bait rigs and deep jigs on the mud edges, with electric or high-gear reels doing most of the work.GearDeep-drop rigsHeavy sinkersDeep-drop combo
    How to ID
    • Elongate body, dark gray to black above with a lighter gray underside
    • TWO dorsal fins, well separated from each other
    • Small scales giving a soft, velvety feel
    • No chin barbel

    Typical: 2–3 ft

    Tell it apart: Two well-separated dorsal fins and no chin barbel — despite the market name 'black cod', a Pacific cod has three dorsal fins and a prominent barbel under the chin.

    Easily confused with: Pacific Cod

Fishing Regulations

Tides & Timing

Read the Tide

Tides run hard through the Aleutian passes and along the Peninsula, and the passes are where wind against a strong tide turns dangerous fastest. The first push of moving water after slack is the halibut and cod bite; salmon push into the lagoons hardest on the incoming.
