Prior to the translocation, a 13-person crew led by GRCA fisheries biologist Brian Healy spent six days surveying the translocation reaches of Shinumo Creek to get population estimates of humpback chub and other native fish (bluehead suckers and speckled dace), and removing nonnative rainbow trout. A number of humpback chub from the 2009 translocation were captured during monitoring, and population estimates are pending. A crew returned to Shinumo Creek in September for additional monitoring.
A new aspect of this project in Shinumo Creek for 2010 is estimating populations of bluehead suckers and speckled dace by marking individual fish with fin clips or PIT tags, which are small microchips that uniquely identify each fish, that are emplaced in the abdomen of the fish that were caught during surveying.
The National Park Service is directing the Shinumo Creek humpback chub translocation experiment, in conjunction with the Bureau of Reclamation, the U.S. Fish and Wildlife Service, and the Arizona Game and Fish Department.
