072: The Science of the Strike: Why Salmon Hunt (And How to Catch Them)

**The Science of the Strike: Why Salmon Hunt (And How to Catch Them)** If you want to stop guessing and start understanding why salmon do what they do, this episode is for you. Jamie breaks down the actual science behind salmon behavior -- how they find food, what triggers a strike, and why your lure action matters more than your lure color. This isn't theory for theory's sake. Every principle connects directly to how you fish. **What this episode covers:** - Why salmon in the Salish Sea are typically found in the upper 30 meters of the water column -- and how to use that to your advantage - Why "current change" is the phrase that should replace "tide change" in your vocabulary - How tidal jets create convergence fronts that stack baitfish -- and why that's exactly where you need to be - What the lateral line is and why it may matter more than vision when it comes to triggering a strike - The real science on color and depth -- and why red is essentially invisible below 33 feet - Why erratic, irregular lure movement triggers predatory instincts in salmon **Timestamps** 00:00 -- Introduction: the science behind salmon and why it makes you a better angler  01:30 -- Salmon School announcement (August 9, Anacortes)  03:00 -- Where salmon hold in the water column and why it matters  04:00 -- Current change vs. tide change: why the language matters  05:00 -- Tidal jets, convergence fronts, and where bait stacks  07:00 -- Using sonar to find fish that won't bite  07:30 -- Salmon diet: herring, sand lance, and matching the hatch  09:00 -- Lure selection: Kingfisher Spoon, Coho Killer, hoochies, and matching prey  10:00 -- The lateral line: how salmon detect your lure before they see it  12:00 -- Why flashers work and why lure action is primary  13:00 -- Color physics at depth: what salmon can actually see  14:00 -- UV and glow lures: what the science says (and doesn't)  16:00 -- What triggers the strike: erratic movement and vulnerable prey  18:00 -- Key takeaways and closing  19:00 -- Salmon School wrap-up **Key Takeaways** - Salmon in the Salish Sea primarily hold in the upper 30 meters -- your depth decisions should be calculated, not random. - Current change -- not tide change -- is the variable that concentrates baitfish and creates feeding windows. - Tidal jets create convergence fronts where herring, sand lance, and candlefish stack -- and where salmon follow. - The lateral line is a fish's built-in pressure and vibration sensor, and research suggests it may be more important than vision for triggering a strike. - Water absorbs red and orange light by about 33 feet deep -- color choices below that depth should lean toward green, blue, and UV reactive. - UV lures have strong anecdotal and industry support, but peer-reviewed science on UV vision in Pacific salmon at fishing depths is still limited. - Erratic, irregular lure movement mimics a vulnerable baitfish -- and that's what gets a salmon from following your lure to striking it. **Resources Mentioned** - Salmon School (August 9, Anacortes): https://anglersunlimited.co/salmonschool - ScienceDirect Lateral Lines & Fish: https://www.sciencedirect.com/topics/veterinary-science-and-veterinary-medicine/lateral-line - Encyclopedia of Puget Sound: https://www.eopugetsound.org/ - What Salmon See: https://www.science.org/content/article/how-salmon-see-world-anew - Pacific Wild (forage fish research): https://pacificwild.org/how-salmon-need-herring/ - Steve Chamberlain previous episode: https://youtu.be/29aTkrlzHWw?si=4ZC-fd9Nz7uAYvlo - Sea Bear Smokehouse: https://seabear.com/pages/about-seabear **Want to fish smarter this season?** We have 13 spots left at Salmon School on August 9th in Anacortes.
