Knowing how to catch salmon starts with one fact: you're intercepting fish on a one-way migration—they stop eating heavily once they enter freshwater, so you're triggering reaction strikes, not feeding bites. Match your approach to the species: kings (chinook) hold deep and respond to plugs, big spoons, and cured eggs; coho (silvers) are aggressive and chase spinners and flashy spoons; sockeye barely strike and are usually taken on small flies and bare hooks drifted into their lane. Time your trip to the run—fresh, chrome fish straight off the salt bite far better than dark, spawned-out fish holding in pools. In rivers, fish current seams, tailouts, and holding slots; on the Great Lakes and saltwater, troll spoons and flashers behind downriggers. Get your presentation to their depth and in their travel path and the strikes come.
The five Pacific species behave differently, and lumping them together is how people get skunked. Chinook (king) are the largest and run deepest—they hold in heavy current and deep holes, and they respond to big, slow, bottom-bouncing presentations. Coho (silver) are the gamefish of the group: aggressive, willing to chase, and a sucker for flash and speed. Sockeye (red) are plankton feeders that almost never strike out of hunger—you catch them by drifting a small fly or bare hook into their open mouths as they hold or move. Pink and chum round out the run; pinks love small pink jigs and spoons, chum hit chartreuse and pink flies and beads.
Atlantic salmon and Great Lakes transplants (kings and coho stocked in Michigan, Erie, Ontario) fish much like their Pacific cousins, just in a lake instead of the ocean.
Salmon are seasonal—miss the run by two weeks and the river is empty. Spring/summer kings push into rivers from late spring through August depending on the system. Fall is prime for most anglers: coho and late kings flood coastal rivers from September into November, and Great Lakes fish stage and run the same window. Sockeye typically run early-to-mid summer. Pinks run on odd years in many Pacific Northwest rivers (the famous "odd-year" pink runs).
Target chrome fish—bright, sea-lice-flecked salmon fresh from saltwater bite aggressively. As fish darken, develop kypes, and turn red or olive, they shut down and care only about spawning. Fish the lower river early in the run for the freshest, most willing fish.
Migrating salmon don't scatter—they travel and rest in predictable lies. Learn to read water and you'll find fish fast:
Cured salmon eggs (roe) are the most consistent river bait, especially for kings. Skein and cured roe drifted under a float or bottom-bounced on a drift rig puts scent and a tight egg cluster right in the strike zone. Cure your own with borax and a commercial cure for color and toughness, or buy pre-cured. Fish a dime-to-quarter-size cluster on a size 1 to 2/0 hook, drifting it at the same speed as the current—drag-free and natural.
Beads (8–12mm) pegged a couple inches above a bare hook imitate a single drifting egg and are deadly on all species, including bead-shy sockeye and coho. Sand shrimp, often tipped behind roe, sweeten the deal for kings.
When you want to cover water or trigger reaction strikes, throw metal and plastic:
Fly anglers swing and dead-drift for all species. Swing flies—Intruders, leeches, and bright comets in pink, chartreuse, purple, and black—on a sink-tip down and across for coho and kings; the grab on the swing is unmistakable. Dead-drift small flies and beads under an indicator for sockeye and pressured coho, since sockeye respond to a fly drifting straight into their mouth far more than to anything swung. Single-hand 7–9 weights work in smaller water; a switch or two-hand spey rod shines on big rivers.
Open-water salmon are taken trolling. Run spoons and cut-bait behind flashers/dodgers off downriggers to reach the depth where fish hold—often 30–90 feet for Great Lakes kings, shallower for coho. Watch your electronics, find the thermocline (kings stack near 50–55°F water), and stagger lines at multiple depths until you dial in the strike zone. Glow and UV finishes shine in low light and deep, dim water. Troll 2–3 mph and vary speed and turns to trigger following fish.
Rods and line: Medium-heavy 8.5–10.5 ft float/drift rods for rivers; 15–30 lb mainline with a lighter leader. Kings demand backbone—don't go light. Leaders: 12–20 lb fluorocarbon for clear water, heavier for off-color flows. Hooks: Sharp, and check local rules—many salmon fisheries require single, barbless hooks. Read the regs: salmon waters have strict, frequently changing seasons, gear restrictions, and bag limits. Check current regulations for your river before you fish.
Salmon are a timing game, and FishRadar takes the guesswork out of the window. The forecast layers water temperature, barometric pressure trends, and solunar bite periods so you know when fresh fish are most likely to move and strike on your river or troll line. Instead of burning a vacation day on a dead bite, check the conditions and target the hours when light, pressure, and temperature line up. Plan your next salmon trip with FishRadar's fishing forecast.
