The following is from a press release issued today by Grand Canyon National Park.
“Grand Canyon, Ariz. — On June 15th, 2009, the National Park Service, in conjunction with the Bureau of Reclamation, the Grand Canyon Wildlands Council, the Arizona Game and Fish Department, and the U.S. Fish and Wildlife Service translocated 300 juvenile humpback chub to Shinumo Creek in Grand Canyon National Park. Monitoring of the new Shinumo Creek humpback chub population by fisheries biologists in early July, as well as data collected by a PIT (a microchip known as a passive integrated transponder) tag scanner installed in the stream, showed that most of the translocated fish had remained in Shinumo Creek. While the long-term results of this translocation experiment will only be known after several years of monitoring, these preliminary data are encouraging.”
This is great news! The humpback chub is on the Endangered Species List and has been hugely impacted on the Colorado River. The translocation appears to have begun well and more are planned for 2010 and 2011. This is a fish that is native to the Colorado River drainage, and whose natural habitat was significantly changed when the river was dammed. Saving this fish is a priority for the National Park Service and their efforts are to be strongly applauded. Thanks go out to all the biologists and others working on this project. I wish you the best of luck. This is a newsworthy effort that we all should support. For more of the news release check out this link.
