I'm a stream ecologist and professor at a small school in Pittsburgh, PA. I recently got a contract with Falcon Guides to write the following popular science title: A Field Guide to Rivers and Streams: Understanding Flowing Waters and Aquatic Life. The work will attempt to convey river science to any interested folk.
I will have a chapter on fish, of course, and would love to showcase some of the work that you all do within it. The permissions contract they've given me does not prohibit use of a shot in any way.
If you're interested in discussing details I would love to hear from you. My professional address is: email@example.com
Hope to hear from you,
