Estimating population size of Sicklefin Redhorse in the Hiwassee River system


May 2018 - March 2019


The Georgia Department of Natural Resources (GADNR) is engaged in collaborative efforts to monitor Sicklefin Redhorse (Moxostoma, undescribed) in north Georgia. Recent monitoring of population in the Hiwassee River system has relied on fyke netting (during spawning migrations) and passive antenna arrays for detecting fish implanted with PIT (passive integrated transponder) tags. The goal of this monitoring is to estimate population size, recruitment, survival, and genetic diversity using non-invasive methods that have minimal impact on the health and survival of Sicklefin Redhorse. We propose to assist the GADNR by developing a model to estimate annual population size, survival, and potentially recruitment, using combined data from fyke netting and PIT antenna arrays.
