From Englobe Corp.: Damien Boivin‐Delisle (left), Jean‐Denis Simard Caption (Upper right): The Melach, a glacier‐fed, fish‐free river in Tyrol (Austria, 47°06’59.9”N 11°08’04.5”E) was used to examine lateral and longitudinal fish eDNA distribution downstream of the source. Fish were placed in cages (visible half‐submerged in the stream in center of the picture) and water samples for eDNA analysis were taken during summer, fall and winter. This picture shows the situation in summer during the early afternoon, which is characterized by high discharge and high turbidity.
