During the River Walk draining from Jan. 11–19, biologists will relocate native fish while removing invasive species to help protect the river’s ecosystem.
SAN ANTONIO — As parts of the River Walk are drained later this month, crews will also be working to protect the wildlife that lives there.
The San Antonio River Authority says biologists will relocate hundreds of native fish and other aquatic species between Jan. 11 and Jan. 19, along the stretch from West Josephine Street to South Alamo Street.
At the same time, crews will remove invasive species like plecostomus, blue tilapia and giant apple snails. More than 2,000 apple snails were removed during the last river draining.
To help keep them from coming back, about 800 feet of experimental barriers will be installed at two locations to slow their reproduction.
River Authority officials say the goal is to protect native species while keeping the river healthy during the City of San Antonio’s maintenance work.
