Environmental DNA, or eDNA, is an evolving new tool that helps us understand the ecosystems below the waves. Water samples with eDNA can show scientists what types of animals are present, how many there are, and how long they’ve been there.
As animals swim, they shed scales, tissue, and waste, leaving traces of DNA in the water. Scientists collect a water sample and analyze the DNA found in it, identifying the species that left it behind without capturing a single animal.
We conduct a variety of genetic research on Pacific salmon, groundfish, and forage fish species to comply with regional, national, and international agreements and treaties for managing marine resources.
