Penn State Researchers Ask Anglers' Help With Study of Trout Colors, Patterns

Penn State researchers, who are evaluating the colors, pattern variations and genetics of wild brook and brown trout across Pennsylvania, are asking anglers to help with their study.

They want anglers to submit photos of wild brook and brown trout they catch and include a special gray card in the frame.

To participate, anglers can request gray cards by going to https://bit.ly/3ij38nW.

The cards will be mailed to participants for inclusion in trout photos.

Anglers simply take a picture of a trout with the gray card in view and submit it via Survey123. Instructions on how to download that app...
