Demographics and Monitoring of Repatriated Razorback Sucker in Lake Mohave: 2011-2014 Final Report
Monitoring of repatriated razorback sucker (Xyrauchen texanus) in Lake Mohave has been conducted for more than twenty years, but low recapture rates have inhibited evaluation of factors contributing to highly variable post-stocking survival. To increase the number of encounters with marked fish, deployment of remote passive integrated transponder (PIT) scanners able to detect 134.2 kilohertz (kHz) PIT tags was initiated in 2011 and expanded in 2012 and 2013, while traditional capture methods were employed to continue to collect comparable long-term monitoring data and estimate abundance of all repatriated and wild razorback sucker marked with either 400 or 134.2 kHz PIT tags.
