Research Task: 832798W.3.0
Task Manager: Jeanette Carpenter
Razorback sucker and bonytail were once common throughout the Colorado River Basin. Both are now federally listed as endangered. Cibola High Levee Pond, historically part of the Colorado River channel, was initially set aside as a grow-out facility for bonytail and razorback sucker. Both species successfully produced thousands of young at the pond, stimulating interest into the mechanisms and factors that led to their survival. This study is examining the early life history of both species in the semi-natural setting of Cibola as well as community composition, fish densities, standing crop, age frequencies, spawning ecology and behavior, and recruitment strategies.
