884 | How to Combine Tight Line Nymphing and Streamer Fishing with Brian DeLoach
Wet Fly Swing Fly Fishing Podcast
#884 Show Notes: Presented By: , , , Sponsors: Progress in fly fishing often happens when you stop treating techniques as separate lanes and start combining them. In this episode, Brian DeLoach shares the hybrid system he’s developed by blending Euro nymphing principles with heavy jig-style streamer fishing to efficiently target predatory fish. Brian explains why stout leaders and heavier rods protect fish during the fight, why drift matters more than tippet visibility, and how changing retrieves—including dead drifts, jig motions, and active strips—can trigger aggressive eats. If...

Howard Croston on Competition Mindset and Loch-Style Fishing for Stillwater Trout (Littoral Zone Podcast #22)
Wet Fly Swing Fly Fishing Podcast
#881 Show Notes: Presented By: , , Sponsors: Stillwater fly fishing rewards anglers who focus on presentation, depth, and efficiency rather than constantly changing flies. In this episode, Phil Rowley sits down with England’s Howard Croston — former world champion, longtime England team member, Hardy product developer, and Fulling Mill fly designer — to unpack the tactical decisions that consistently put trout in the net. From reading unfamiliar lakes and understanding stocked fish behavior to leader diameter, drift control, and eliminating “myths” about fly color, Howard explains...

#880 Show Notes: Presented By: , , Sponsors: There’s a point in fly fishing where casting stops being the hard part, and decision-making takes over. In this episode, Dave Stewart is joined by Nick Elcheson from Scott Lake Lodge to break down sight fishing Northern Pike in shallow water, where patience, positioning, and timing matter more than power. Nick explains why fly fishing for pike is essentially freshwater flats fishing, how seasonal water temperature controls fish location, and why waiting for the right fish often leads to better outcomes than covering water. You’ll...

Wet Fly Swing Fly Fishing Podcast
#877 Show Notes: Presented By: , , , Sponsors: Fly fishing in Southern California looks nothing like a mountain river—and that’s exactly why it works. In this episode, Frank Vargas breaks down how surf fly fishing actually functions, from reading tides and beach structure to understanding how species like perch, corbina, and leopard sharks use shallow water to feed and travel. Frank shares how incoming and negative tides reveal feeding lanes, why anglers often walk past productive water, and how sight fishing in the surf can feel more like targeting carp than blind casting waves....

876 | How to Build an Adventure Vehicle with Matt Dunkerly of AVC Rig
Wet Fly Swing Fly Fishing Podcast
#876 Show Notes: Presented by: Most adventure rigs look great online. Fewer are built for real miles, real weather, and those long fishing days that end well after dark.

Presented By: Stonefly Nets, TroutRoutes, Smitty's Fly Box
In today’s Littoral Zone episode, Phil chats with Jason Randall about what trout see and why it matters.
Jason has written four books, including his famous trout trilogy, which dives deep into how trout behave in their environment. While Jason's passion lies in rivers and streams, the research and knowledge he's amassed is equally beneficial to stillwater fly fishers.
]His understanding of how trout see is crucial information for all fly fishers, guiding both our pattern selection and presentation techniques, information that helps us consistently make the correct pattern and presentation choice.
Show Notes with Jason Randall on What Trout See and Why it Matters.
2:20 - Jason Randall graduated as a veterinarian and did postgraduate work in fish health and medicine. Although he considered a career in fisheries, he ultimately chose private practice.
4:16 - Jason started fly fishing around 40 years ago but got frustrated early on due to a lack of guidance. He took a break, then later tried again this time with the help of great mentors.
Jason says his passion really started during a trip to Colorado. A guide introduced him to a caddis hatch that transformed the river into a feeding frenzy of trout. Watching the stream come alive with caddis and rising fish was a game-changer for Jason.
08:21 - Jason says he was lucky to have some amazing mentors like George Kustin who guided him in fly fishing and taught him about wet flies and soft tackles. Lefty Kreh took Jason under his wing.
09:31 - Jason also works with Temple Fork Outfitters on rod design and prototype testing. This year, they introduced a new European Nymphing Rod called the Elevare, which won Best New Rod at ICAST 2024.
Books by Jason Randall
13:00 - Jason’s trout fishing trilogy started in 2012 with Jay Nichols from Stackpole Books. The trilogy covers:
Feeding Time: A Fly Fisher’s Guide to What, When and Where Trout Eat
Trout Sense: A Fly Fisher’s Guide to What Trout See, Hear, and Smell
Moving Water: A Fly Fisher’s Guide to Currents
Jason also wrote Nymph Masters, a collaborative effort featuring tips from top nymph anglers like Gary Borger and Lefty Kreh.
Trout Sense
17:00 - Trout begins life as prey, eating small organisms like plankton. As they grow, they become predators, feeding on insects, crustaceans, and even small fish or mammals.
They retain the wide-set eyes of prey for spotting threats and the sharp focus of predators for hunting. This makes them tricky to catch.
21:10 - Jason explains how light works differently underwater, which affects how trout see. Refraction, or the bending of light when it moves from air to water, can also trick us into thinking we're casting right over a fish, but we could be a few feet off.
26:08 - Jason dives into how color fades underwater, starting with red, and how different colors are absorbed at various depths. Fluorescent colors like chartreuse stand out the most and create a strong contrast, which trout notice.
29:18 - Unlike humans, a trout's pupils don’t adjust to light, and their eyes have a football-like shape that lets them see clearly both in front and to the side.
Search Image and How Trout Decide to Eat
42:11 - Trout uses a "search image" to figure out what’s food and what’s not. They focus on four things: size, shape (profile), movement, and color.
If a fish keeps ignoring your fly from far away, it’s probably the size or shape that’s off. But if they come close, and then turn away, Jason says that it may be a color-based refusal.
