San Antonio River Guadalupe Bass Project

This project assessed the abundance of Guadalupe Bass Micropterus treculi in the San Antonio River (SAR) watershed and collect, tag and reintroduce the species to a restored reach of the SAR where the species had been extirpated. An assessment of Guadalupe bass in the SAR watershed was completed to gather genetic and baseline abundance information. Collected adults were tagged, checked for genetic integrity, and stocked in restored stream reaches. Evaluation of efforts began six months after stocking to document movement, reproduction and recruitment. Habitat association data was collected to help guide future habitat restoration efforts. Overall outcomes include reintroduction of the Guadalupe Bass to the Upper SAR, expanding its range and distribution and improving the biotic integrity of the Upper SAR.
