Northern pike are native to much of Alaska, but south of the Alaska Range, they’re an invasive species, and their continued spread raises new questions.

In this episode of The Fish Count, we sit down with ADF&G research biologist Parker Bradley to talk about northern pike in Southcentral Alaska. We dig into how pike were introduced to the region, how they spread through connected waters, and why their impacts on native fish, particularly juvenile salmon, can vary dramatically depending on habitat.

We also explore one of the most fascinating areas of current pike research: evidence that northern pike are moving through the brackish waters of Cook Inlet to reach new freshwater systems. Parker explains how researchers use otolith microchemistry, salinity studies and video weirs to better understand where these fish have been and what their movement could mean for Southcentral Alaska fisheries.

Along the way, we tackle some common misconceptions about northern pike, look at what researchers have learned from examining tens of thousands of pike stomachs, and discuss why preventing the spread of invasive species matters.

It’s a wide-ranging conversation about pike, salmon, invasive species and the research helping us better understand what’s happening beneath the surface.

What can years of fish research reveal about Alaska's freshwater predators? In this episode of The Fish Count, host Ryan Ragan sits down with Alaska Department of Fish and Game research biologist Matt Albert to explore the fascinating world of northern pike and lake trout.

Matt shares stories from the field, explains how fisheries biology and radio telemetry help biologists track fish movements, and discusses what years of research have taught us about the behavior, habitat, and management of these remarkable sport fish. As an avid angler, he also shares his favorite Alaska fishing experiences, where anglers can find outstanding opportunities for northern pike and lake trout, and how science has changed the way he fishes.

Whether you enjoy chasing salmon, rainbow trout, northern pike, or lake trout, this episode offers a behind the scenes look at fish research, fish management, and the people working to sustain Alaska's world class sport fishing opportunities.

In this episode of The Fish Count, we head to the Susitna drainage with three Alaska Department of Fish and Game biologists for a behind-the-scenes look at one of the state's most important sport fisheries. Learn how fish weirs, sonar, fish wheels, genetics, and aerial surveys help biologists monitor salmon runs and make in-season management decisions. Along the way, you'll hear personal stories from the field, discover what it's like to work in some of Alaska's most remote places, and gain a better understanding of the science, challenges, and passion behind managing Alaska's world-class fisheries. Whether you're an angler, an outdoor enthusiast, or simply curious about how fisheries are managed, this episode offers an engaging look at the people and science that keep Alaska's fisheries sustainable.

Rockfish are among Alaska's most fascinating fish. Some species can live for more than 200 years, produce millions of offspring, and spend their entire lives on the same underwater reef. In this episode of The Fish Count, we dive beneath the surface with Alaska Department of Fish and Game biologists to explore the remarkable biology, behavior, and management of Alaska's diverse rockfish species. Learn how scientists study these long-lived fish, why proper release techniques are critical for their survival, and what anglers can do to help conserve these incredible residents of Alaska's marine waters. Whether you're an experienced saltwater angler or simply curious about the hidden world below the waves, this episode offers a fascinating look at one of Alaska's most extraordinary fish.
