Stable Isotope Analysis of Centrarchid Concentration AreasWebsite or Online Data - 2007
This project addressed movement of nonnative fish into river reaches of critical habitat for endangered fishes from floodplain habitats. Nonnative fishes of the Family Centrarchidae are known to occur in floodplain ponds, backwaters, beaver ponds, washes and irrigation drainage ditches throughout the Grand Valley reach of the Colorado River. The primary objectives of this project were to determine whether the origins and movements of centrarchids in an 87-mile reach of the upper Colorado River and adjacent floodplain habitats could be identified using naturally occurring stable isotope and/or microchemical analyses, and determine the proportion of centrarchids in backwaters within the study area that originated from out-of-channel ponds versus in-channel habitats.
