Coastal Cutthroat Trout
Coastal cutthroat trout are a native Pacific salmonid that anglers in British Columbia fish in two distinct settings: small coastal streams and rivers for resident fish year-round, and tidal estuaries and saltwater bays for sea-run fish returning in late summer and fall.
BC sits in the heart of their range, and the fishery here — particularly for sea-run fish in tidewater — draws dedicated fly anglers chasing one of the coast's most accessible wild trout.
Also known as Sea-run cutthroat, blueback trout, harvest trout, speckled trout
- Distinctive red, orange, or yellow slash marks under the lower jaw on both sides — the clearest field mark separating them from rainbow trout.
- Heavy, irregular black spots scattered across the entire body including below the lateral line and onto the fins — denser spotting than a rainbow.
- Upper jaw extends past the rear edge of the eye, even on smaller fish; freshwater residents develop a dark copper-brass tone with iridescent flanks.
- Sea-run fish are silvery with an aquamarine back; most fish run 12–18 inches, with fish over 20 inches considered exceptional.
What to know
Habitat Distribution
- Native to BC's entire Pacific coast — from the Lower Mainland and Vancouver Island north through the Central and North Coast to the Alaska border, bounded inland by the Coast Range.
- Rarely found more than 100 km from tidewater; distribution closely follows the coastal temperate rainforest belt and overlaps with coho, steelhead, and pink salmon watersheds.
- Sea-run fish use estuaries, saltwater bays, and nearshore marine waters — typically staying within 8–16 km of their home stream — before ascending rivers in fall.
- Resident and lake-form fish occupy small, low-gradient coastal streams, beaver ponds, and lake systems throughout coastal BC.
Key Locations
- Vancouver Island — numerous small coastal streams and estuaries hold both resident and sea-run fish; the island's west coast rivers see strong fall runs of sea-run cutthroat.
- Lower Mainland (Greater Vancouver area) — coastal streams draining into Burrard Inlet, Howe Sound, and the Fraser estuary support fishable populations accessible to urban anglers.
- Central and North Coast BC — rivers and streams draining into Douglas Channel, Dean Channel, and the Skeena watershed's coastal tributaries hold cutthroat in relatively undisturbed habitat.
- Haida Gwaii — remote island streams support healthy resident and sea-run populations with minimal fishing pressure.
Specific Spots
- In streams, target deep summer holding pools, undercut banks, and log jams — cutthroat use overhead cover to stay cool and intercept food drifting through.
- In tidal reaches, fish the seam where fresh and salt water meet; sea-run fish stage in these transition zones before moving upstream.
- In saltwater bays and estuaries, work shallow gravel beaches and kelp edges on a falling tide when baitfish concentrate near structure.
- In lakes, focus on inlet and outlet streams, submerged timber, and drop-offs adjacent to shallow shoals where forage fish gather.
Coastal Cutthroat Trout FAQ
Answers from onWater's species guide.
What are the best lures and bait for Coastal Cutthroat Trout?
Small spinners (size 0–2 Mepps or Blue Fox) and inline spinnerbaits are reliable across BC coastal streams, the flash and vibration draw strikes from fish holding in pools and behind structure.
What flies work for Coastal Cutthroat Trout?
Streamers are the most versatile category: Woolly Buggers (imitating leeches or small fish) and Muddler Minnows (imitating sculpins and baitfish) cover both stream and estuary situations, strip them with short, erratic pulls to trigger strikes.
When is the best time to fish for Coastal Cutthroat Trout?
Summer (June–August): Resident stream fish are active; sea-run fish are feeding in nearshore marine waters and not yet in rivers. Late summer–fall (August–October): Peak season for sea-run fish as they move into coastal bays, estuaries, and tidal rivers, the most targeted window for BC cutthroat anglers.
How do you catch Coastal Cutthroat Trout?
Most BC anglers fish coastal cutthroat from shore or by wading, either working small coastal streams with light spinning or fly gear, or walking tidal beaches and estuary flats during the late-summer sea-run migration. Boat fishing is used on larger tidal systems to cover estuary structure and reach river mouths.
What do Coastal Cutthroat Trout eat?
In freshwater, cutthroat eat aquatic insects, mayfly and caddisfly nymphs and adults, plus terrestrials like beetles, ants, and grasshoppers that fall from streamside vegetation; match these with Elk Hair Caddis or Parachute Adams dry flies, or Pheasant Tail and Hare's Ear nymphs fished dead-drift (drifted naturally...
