With chrome-bright bodies, explosive speed, and relentless energy, Coho salmon bring a level of excitement that transforms an ordinary fishing day into something unforgettable. Known as Silvers for their gleaming flanks, Coho are among the most athletic and entertaining sportfish in the Pacific. In the waters surrounding Haida Gwaii, and especially in the highly productive expanse of Cartwright Sound, Coho fishing delivers fast-paced action that keeps anglers engaged from the first strike to the final net.
For guests at Sandspit Adventures, Coho salmon fishing is a defining part of the summer season. Whether arriving early or fishing during the late-summer peak when Northern Coho reach their full size and strength, anglers experience one of the most dynamic fisheries on the West Coast. Cartwright Sound consistently produces aggressive Coho that strike hard, fight wildly, and put on aerial displays that energize the entire boat.
The Silver Salmon: Built for Speed and Spectacle
Coho salmon are instantly recognizable by their metallic blue backs, bright silver sides, and distinct black spotting on the upper portion of the tail. While smaller than Chinook, Coho are engineered for agility and acceleration. Their streamlined bodies and powerful tails allow them to change direction quickly and launch into dramatic leaps when hooked.
In Haida Gwaii, Coho typically range from eight to fifteen pounds, with larger fish appearing later in the season. While size plays a role in their appeal, it is their behavior that truly sets them apart. Coho are known for:
- Explosive surface strikes
- Multiple high jumps during a single fight
- Fast, erratic runs near the surface
- Sudden directional changes
- Tenacity all the way to the boat
Each encounter feels energetic and unpredictable. Coho fishing rewards alert anglers and keeps everyone onboard watching closely, waiting for the next eruption of silver.
Why Cartwright Sound Is a Coho Salmon Hotspot
Cartwright Sound lies just a short run from the Sandspit Adventures dock along the eastern edge of Haida Gwaii. Its unique combination of deep channels, kelp forests, reef systems, and protected coves creates a highly productive marine environment.
During summer months, large schools of herring and needlefish concentrate in the Sound. Coho follow these baitfish closely, often feeding near the surface or along tide lines where currents compress forage into tight zones. The mix of sheltered waters and open points allows guides to target Coho effectively across a wide range of conditions.
Haida Gwaii also sits directly along major salmon migration pathways. Coho moving south from the Gulf of Alaska or returning to river systems throughout British Columbia and the Pacific Northwest pass through these channels. When food is abundant, as it reliably is in Cartwright Sound, Coho pause to feed aggressively, creating ideal fishing conditions.
The First Run: When Coho Make Their Move
A Coho strike is often sharp and immediate, followed by a burst of speed that signals what is coming next. Unlike Chinook, which frequently dive deep, Coho tend to stay high in the water column. Their first run often sends them racing across the surface, leaving visible wakes and foam trails behind.
Then come the jumps.
Coho are famous for launching themselves clear of the water, twisting and shaking in an effort to throw the hook. These aerial displays bring cheers, laughter, and moments of shared excitement. It is common for a single fish to jump multiple times during a fight, flashing its silver sides in the sunlight with each leap.
For many guests at Sandspit Adventures, these moments define Coho fishing. The combination of speed, spectacle, and unpredictability makes every hookup feel electric.
Why Coho Fishing Thrives at Sandspit Adventures
While Coho salmon are found along much of the Pacific coast, several factors make Cartwright Sound and Sandspit Adventures uniquely effective.
Abundant Bait and Ideal Feeding Conditions
Complex currents and structure create consistent mixing zones that support herring, needlefish, anchovies, and juvenile rockfish. With food readily available, Coho remain aggressive and visible.
Multiple Coho Waves Throughout the Season
Early Coho arrive in late June, with numbers building through July. Late July and August bring Northern Coho that are thicker, stronger, and highly active. This extended season allows for excellent fishing across the summer.
Low Fishing Pressure
Haida Gwaii remains uncrowded compared to many coastal fisheries. Fewer boats mean less disturbance, more predictable fish behavior, and a more relaxed experience.
Close Proximity to Prime Water
Cartwright Sound lies close to the lodge, reducing travel time and allowing more flexibility to adapt to changing conditions throughout the day.
Versatile, Adaptive Techniques
Coho respond well to a range of presentations. Guides adjust tactics based on weather, tide, and fish behavior to maximize success.
Techniques That Bring Out the Best in Coho Fishing
Coho are highly reactive fish, making them ideal for anglers who enjoy active and engaging fishing styles.
Trolling Along Tide Lines
Tide lines where opposing currents meet concentrate bait and salmon. Trolling spoons or small bait presentations along these seams often produces quick strikes in shallow water.
Mooching for Feeding Silvers
Coho readily take a well-presented cut-plug herring. Mooching provides direct contact with the fish and creates a vertical fight that showcases their speed and jumping ability.
Casting Into Surface Activity
When Coho are feeding near the surface, guides may position the boat so anglers can cast spoons or spinners directly into visible action. This approach offers some of the most visually exciting fishing available.
Light Tackle Opportunities
When conditions allow, lighter tackle enhances the experience. Every run, jump, and direction change becomes more pronounced, turning each fish into a memorable challenge.
The Culinary Reward of Coho Salmon
Beyond their sporting qualities, Coho salmon are prized for their rich flavor and firm texture. Their flesh is well suited for grilling, baking, and smoking, making them a favorite for home preparation.
At Sandspit Adventures, fish are professionally processed and flash-frozen to preserve peak quality. For many guests, sharing Coho meals with family and friends becomes a way to relive the experience long after the trip ends.
