Arctic Grayling

These photos represent two days of a project to survey, and capture eggs to produce fertilized gametes to be used in repopulating the Arctic Grayling fish population in Red Rock Creek, Elk Springs Creek and Elk Lake in the Centennial Valley of Montana. US Fish and Wildlife and Montana Fish and Wildlife agencies are cooperating in this multi-year project to bring the Arctic Grayling back from near endangered species status in the lower 48 states. Photography by James N Perdue.

  • This is a fish dam which collects specimens of fish going upstream (closest to nearest bank) and downstream (closest to far bank). Biologists inventory every fish as to species, weight, length and sex. They then mark their fins by cutting a small piece off (it regrows) and puts in in Red Rock Creek upstream to continue their spawning process.
  • The US Fish and Wildlife Biologist collects some of the upstream fish from the fish trap prior to measuring them. Red Rock Creek, May 2012
