About The Scientific Fly Angler

Jason G. Freund

Welcome to my COVID project.

This page explores fly fishing and fly tying from an mostly - but not entirely - scientific point of view. Expect a random collection of fly tying, fish and stream ecology for the fly angler, and well, whatever I feel like posting at the time. From time to time, I will branch out from fly fishing into fisheries management and science.

This website and blog is for fun - not profit. I'm coming at you from Wisconsin's Driftless area but am hoping to interact with anglers from around the world. It is not necessarily a blog about Wisconsin but we are shaped by our experiences.

Send me an e-mail if you have question, comments, ideas for posts, etc.

Cicadas are big, clumsy bugs that are really poor flyers and run into things quite regularly - this includes the water's surface.

Understanding Trout Populations through Secondary Production and P/B Ratios

I often write these blog posts because they are research topics I am interested in, this being one of those times...it's about fish.

Project Terrestrial - The Classics (Part IV)

The classics work. I like foam flies - but there is a time and a place for non-foam terrestrials. Here are a number of classics to consider.

The When and Where of Fishing Terrestrial Flies

If I had to pick a month of days to fish for pure enjoyment and often a great challenge; it would be from mid-August through mid-September.

Project Terrestrial: To Foam or not to Foam (Part III)

Foam is a great and versatile tying material that is particularly well-suited for high floating flies.

Project Terrestrial - Thoughts on Terrestrial Fly Patterns (Part II)

Don't overthink it - often when food is rather scarce, as it tends to be in streams in mid-summer, trout can not afford to be overly choosy.

Project Terrestrial - Part I: Ants, Beetles, Hoppers, and Crickets, oh my!

Why terrestrials? Aside from terrestrials being fun as can be? Do you really need more than that? OK - then let's dig into the why...

To Dry and Dropper or Not?

Conventional wisdom states that "it is a 2-for-1" so you may as well fish the dropper...but it can be such a pain in the ass!

Aquatic insects in the spring, terrestrials in the Summertime

Experienced trout anglers know this idea well - in the spring and fall, aquatic insects are key. In the summer, terrestrials are key.
