27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Biography & Thoughts

Dave Ruiter (username Creno) was one of the all-time most valuable and prolific contributors to the Troutnut.com community, generously sharing his deep knowledge as a professional caddisfly expert and helping me with countless caddisfly identifications. Sadly, he passed away in 2021 at age 73. On Trichoptera.org I found a touching tribute to him and wanted to share it in his profile here. —Jason/Troutnut
