#65 || Colin Gallagher: The Secret Life of Lake Trout

2026-11-0301:10:41

We like to think we know about lake trout, but what if we've been underestimating these remarkable fish? What if lake trout have individual behavioural patterns, know their way around an entire lake and can find their way home after being moved miles away? And what happens to these visual feeders when the sun never sets in the summer or barely rises in the winter? Fisheries scientist Colin Gallagher takes us inside the surprisingly complex world of lake trout. His research reveals individual ...

#64 || Jeff Matity: Jumbo Perch - Find 'Em, Fool 'Em, Catch 'Em!

2026-10-1301:20:03

If you want to catch more and bigger perch, forget the guesswork! In Part 2 of our Doc Talks Fishing conversation with Saskatchewan fisheries biologist and passionate perch angler, Jeff Matity, we're turning science into fish-catching strategies. Where do jumbo perch go as the seasons change? Why can you catch scores of jumbos one day while you scratch your head the next day? Jeff tells us how he eliminates unproductive water, uses his electronics to locate fish, and deploys clever search-and...

#63 || Jeff Matity: The Secret Life of Yellow Perch

2026-09-2201:11:49

When we think about yellow perch, it’s usually about watching a slip bobber disappear and the scrumptious fillets that follow. But yellow perch are one of the most important fish in freshwater, often fuelling entire aquatic ecosystems. From giant walleyes and northern pike to muskies and countless other predators, some of the most sought-after fish in North America owe their growth, success and existence to yellow perch. Yet despite their importance, most of us know surprisingly little about ...

#62 || Dr. Trevor Keyler: The Hidden World Through a Walleye’s Eyes

2026-09-0155:42

Dr. Trevor Keyler has spent years investigating what the underwater world looks like through the eyes of a walleye. His research reveals a fish with an astonishingly sophisticated visual system — one perfectly adapted to hunting in the low-light world beneath the surface. Trevor explains how walleye eyes capture incredibly faint light, why they're most sensitive to the blue-green wavelength and how water clarity dramatically changes the underwater light environment. And then there's this jaw-...

#61 || Dr. Joe Langan: The Salmon That Broke Biology

It is a fisheries science story that has biologists shaking their heads in disbelief. In this episode of Doc Talks Fishing, Dr. Joe Langan takes us on an extraordinary journey—from the surprising history of how pink salmon first arrived in the Great Lakes, to the mystery of where they disappear for most of their lives, to bizarre "Pinook" (pink/chinook) hybrids that exist nowhere else on Earth. t's an unforgettable story of adaptation, evolution and a remarkable fish that simply refuses to fo...
