How To Catch Squawfish: The Complete Angler's Guide

Successfully targeting the northern pikeminnow, historically known as the squawfish, requires understanding their predatory feeding habits, aggressive strikes, and seasonal migrations in major river systems. By deploying precise bottom-bounce rigs, matching specific baitfish profiles, and capitalizing on state-sponsored sport-reward programs, anglers can consistently land these hard-fighting native predators.

Northern Pikeminnow Habitat and Gear Preparation

Targeting northern pikeminnow efficiently demands specialized tackle capable of handling heavy river currents and rocky bottom structures where these fish ambush prey. Squawfish are opportunistic omnivores that transition from eating aquatic insects as juveniles to becoming voracious piscivores once they exceed 10 inches in length. Because they aggregate heavily below hydroelectric dams, in deep tailraces, and along current seams during spring and summer months, your equipment must be tailored for heavy-duty freshwater bottom fishing.

• Essential Gear and Tackle: Medium-heavy spinning rods (7 to 8.5 feet) paired with 3000 to 4000 series reels spooled with 20-pound braided main line and a 12-to-15-pound fluorocarbon leader. Terminal tackle requires sliding slip-sinkers (1 to 3 ounces depending on current speed), barrel swivels, and size 2 to 2/10 octopus hooks.
• Bait and Artificial Selection: Fresh or frozen northern squawfish meat strips, chicken liver, nightcrawlers, and imitation minnow plastics or marabou jigs in chartreuse, white, or silver finishes.
• Prerequisite Knowledge and Regulations: Review local state fish and wildlife department regulations regarding bag limits, invasive species protocols, and participation guidelines for commercial reward programs that compensate anglers for turning in harvested fish over a specific size threshold.
• Budget and Timeframe Benchmarks: Initial gear setup ranges from $80 to $200. Optimal fishing windows span from May through September, focusing on dawn and dusk low-light periods or high-flow generation cycles at major dam tailraces.

Step-by-Step Execution for Targeting and Landing Squawfish

Step 1: Locate Prime River Structures and Current Seams

Scan river systems for tailraces, rocky riprap banks, bridge pilings, and eddy lines where fast water meets slower holding water. Squawfish utilize these structures to conserve energy while waiting for disoriented baitfish swept down from upstream turbines or rapids. Use a depth finder or shore observation to identify transitions from shallow gravel bars to deep, 10-to-30-foot channels.

Pro-Tip: Focus your efforts immediately downstream of hydroelectric dam exclusion zones where injured salmon smolts and coarse fish concentrate, creating a natural feeding frenzy for resident pikeminnow.

Step 2: Rig Your Rod for Bottom-Bounce Presentation

Slide a 2-ounce slip-sinker onto your main braided line, followed by a plastic bead to protect your knot, and tie the line to a high-strength barrel swivel. Attach a 24-to-36-inch fluorocarbon leader to the opposite end of the swivel, terminating at an octopus hook. Thread a fresh piece of bait—such as a 2-inch strip of squawfish belly meat or a plump nightcrawler—onto the hook, ensuring the point is fully exposed for a solid hookset.

Step 3: Cast Upstream and Manage Your Drift

Cast your rig at a 45-degree angle upstream into the current, allowing the sinker to sink and maintain continuous contact with the river bottom. Reel in excess slack as the current sweeps your rig downstream in a natural arc. As the rig ticks over rocks and gravel, be prepared for a sharp, aggressive tap rather than a slow, dragging weight.

Warning: Avoid using excessive static weights that pin your presentation to one spot; squawfish prefer a moving, natural presentation that mimics a struggling or disoriented baitfish drifting with the current.

Step 4: Detect the Strike and Set the Hook Firmly

Northern pikeminnow strike with surprising aggression, often delivering a rapid series of sharp thuds followed by a steady pull. Lower your rod tip slightly to give the fish a split second to take the bait fully, then sweep the rod upward and backward with authority to drive the heavy-gauge hook through their tough, bony jaws. Maintain steady, high-rod pressure during the fight to prevent the fish from diving back into snag-heavy boulder fields.

Northern Pikeminnow Versus Common River Predators

Troubleshooting Common On-Water Failures

• Root Cause: Missing strikes consistently without hooking up. Actionable Fix: Squawfish have bony mouths; switch from a traditional circle hook to a sharp offset octopus hook, and ensure you wait for a definite downward pull before setting the hook.
• Root Cause: Constant bottom snags and lost terminal tackle. Actionable Fix: Reduce your sinker weight to allow the rig to lift and drift more naturally over rocks, or switch from a fixed slider to a breakaway dropper line setup.
• Root Cause: Zero bites in previously productive tailrace locations. Actionable Fix: Check dam water generation schedules; pikeminnow feeding activity spikes dramatically during turbine operation when disoriented prey is flushed downstream.

Frequently Asked Questions

What is the best bait to catch squawfish?

Fresh cut bait—specifically strips of northern squawfish meat, fresh prawns, or chicken liver—yields the highest catch rates. Live nightcrawlers fished on a sliding sinker rig also act as an exceptional universal attractant in both rivers and reservoirs.

Are squawfish good to eat?

While technically edible, northern squawfish possess a soft, oily texture and numerous small intramuscular bones that make them largely undesirable for table fare. However, many anglers process them into fertilizer or participate in sport-reward programs that pay bounty money for harvested fish.

Why are anglers targeting squawfish aggressively?

State and federal wildlife management agencies encourage the removal of northern pikeminnow to protect endangered and threatened Pacific salmon and steelhead smolts from heavy predation in the Columbia and Snake river basins.

What time of day is best for squawfish fishing?

Early morning hours from dawn until two hours after sunrise, as well as late evening dusk periods, offer the peak window for aggressive shallow-water feeding behavior. Overcast days also extend productive fishing hours into the afternoon.

Can you catch squawfish on artificial lures?

Yes, anglers frequently catch pikeminnow on artificials while casting for other species. Chartreuse and white marabou jigs, small crankbaits, and silver spoons retrieved near rocky current breaks produce consistent strikes.
