A Safe Harbor Agreement in-acted in 2009 on two ranches in the Leslie Creek Watershed has allowed refuge staff to move several thousand federally listed native fish into waters on the ranches.  It is important that refuge staff monitor the success of these relocation efforts for future stocking of native fish.  This year's monitoring showed good numbers for the Yaqui chub with over eight-hundred captured.  Using statistics to measure the occupation rates of chub in the two wetlands surveyed, it showed about 75% occupancy in 1 pond and 35% in the other.  So far, only Yaqui chub and Yaqui topminnow have been moved onto the ranches, but with the success of a captive breeding program for Yaqui beautiful shiner at the refuge headquarters, a release of this native fish is planned for this year along with additional chub and topminnow.
