Fish jumping toward filter

Caption

A Coho salmon leaps out of the water toward the researcher’s filters, visible on the ladder at the top of the image. While splashes and fish activity can contribute DNA to the air, airborne DNA also arises from natural processes such as aerosolization, spray, and evaporation at the water surface. The team detected salmon DNA in air samples even where no fish were actively jumping.
