Thanks for watching! Let us know what topics you'd like to hear about next in the comments! In Episode 3 of the TCO Flycast, John Parisi returns to take a deep dive into trout behavior and how it shapes your approach on the water. We break down the three major factors that drive fish movement and feeding: flow, water temperature, and clarity. The conversation moves through seasonal changes from winter and post-spawn behavior into spring hatches, summer terrestrials, and fall patterns. John also covers species differences, stocked versus wild trout, fishing pressure, and how to adjust your presentation based on conditions. If you want to fish smarter and make better decisions before you step into the stream, understanding trout behavior is the foundation.Leave us a comment with the topics or questions you’d like us to cover, and your question could be featured on the next podcast!Support this podcast by choosing TCO for all your fly fishing needs.
