This past summer, I conducted research using stable isotope analysis on 24 different species of fish from Catatonk Creek in Candor, New York. These 24 species existed at different points over the past 100 years and many of them coexisted and interacted. I handled each species and was able to take note of their specific traits. I then created these images in water color and colored pencil to illustrate the morphological differences across each species. I used the illustrations on the research poster that I brought to and presented at the Ecological Society of America's annual conference.
