Austin city officials have released grass carp into Lake Austin to control the invasive hydrilla plant.

Hydrilla, a fast-growing aquatic plant, threatens the lake’s water quality and recreational activities. City authorities introduced grass carp as a biological control to reduce hydrilla growth. The fish are known for consuming large amounts of aquatic vegetation and are sterile to prevent reproduction.

The release follows reports of hydrilla spreading across the lake, affecting boating and fishing. Biologists from the Texas Parks and Wildlife Department collaborated with city officials to oversee the release. Officials will monitor both the grass carp population and hydrilla levels to measure effectiveness.

The city aims to educate the public about ecological balance while exploring long-term solutions for invasive species management. 

City officials remain vigilant in monitoring the balance between grass carp and native species. Updates on hydrilla levels and grass carp populations will be shared with the public.
