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.

There is No Substitute for Getting Out There

There is no magic fly. There are no magic streams. Like anything in life, you get better at something the more you do it.

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.
