This week on Doc Talks Fishing, we crawl into the fascinating-and alarming-world of crayfish with renowned biologist Dr. Premek Hamr.

From native species quietly working behind the scenes to the aggressive takeover by rusty crayfish, "Dr. Crayfish" pulls back the curtain on one of the most under-appreciated but ecologically powerful players in our lakes and rivers. What makes rusty crayfish such effective invaders? How do they displace native species-and what does it mean for our favorite gamefish?

Whether you're an angler, biologist, or just curious about the wild lives happening beneath the surface, this episode delivers science you can use.

Learn how these armoured intruders reshape underwater habitats, alter food webs, and impact fish populations. It's a freshwater battle you don't want to miss.
