Fishing Surprises: Caught in the River Walk’s Depths
San Antonio, TX – A recent TikTok video has unveiled the unexpected presence of fish in the San Antonio River Walk, surprising many locals who were unaware of the waterway’s aquatic life.
Unexpected Catch Reveals River’s Depth
A San Antonio TikTok creator shared a video of himself fishing in the River Walk, where he caught a fish he believed to be a tilapia. The clip quickly went viral, amassing over 170,000 views. Viewers expressed astonishment, with many commenting that they didn’t know fish inhabited the River Walk. The creator responded by stating that he has been fishing there regularly since the early days of the COVID-19 pandemic and has consumed the fish without issue.
Understanding the River Walk’s Aquatic Life
Despite its urban setting, the San Antonio River Walk is part of the San Antonio River, which supports various aquatic species, including carp, catfish, bass, sunfish, and tilapia. Tilapia, an invasive species in Texas, thrive in warm, slow-moving waters like those found in downtown San Antonio. The River Walk’s depth varies; in the downtown area, it is typically 3 to 4 feet deep, but it can be deeper in sections near the lock and dam on the Museum Reach. This depth supports a diverse ecosystem, including fish species.
Fishing Regulations and Water Quality Considerations
Fishing in the San Antonio River Walk is permitted with a valid Texas fishing license. Tilapia are classified as an invasive species and have no size or bag limits. However, anglers are advised to exercise caution regarding water quality. The San Antonio Water System acknowledges that treated recycled water is used to help maintain water levels during dry periods, particularly when spring flows are low. Environmental agencies generally advise caution when consuming fish from urban waterways due to potential exposure to pollutants and runoff, even when fishing is legal.
