If you look deep into the eyes of a fish, it will tell you its life story.
Scientists from the University of California, Davis, demonstrate that they can use stable isotopic analysis of the eye lenses of freshwater fish including threatened and endangered salmon to reveal a fish s life history and what it ate along the way.
They conducted their study, published today in the journal
Methods in Ecology and Evolution, through field-based experiments in California s Central Valley. The study carries implications for managing floodplains, fish and natural resources; prioritizing habitat restoration efforts; and understanding how landscape disturbances impact fish.
