Fish are well-adapted to blend into their surroundings, especially when viewed from above. The same camouflage that hides small fish from hungry birds also makes them difficult to survey from land. To effectively survey fish populations at a site, fish biologists must sometimes leave dry land and meet the fish at their own level. This results in a snorkel survey, which is pretty much what it sounds like: a biologist, a snorkel, and often a wetsuit, depending on water temperature. By bringing a camera along, the biologist can record fish activity at a site and share it with others involved with a project, helping to show progress, plan project improvements, and secure grant funding.
In this video, biologist John Crandall uses underwater footage shot during a snorkel survey last year to show the effects of the 2013 WDFW Floodplain project in a channel feeding into the Methow River.
