A downstream barrier experiment conducted by Great Lakes Science Center used a Smith-Root temporary fabric barrier to stop round goby.
After laboratory feasibility testing, an experimental barrier was placed on the bed of the Shiawassee River, between two nets. The barrier fabric was 20 feet wide and contained four wire rope electrodes. Marked round gobies, a benthic species, were placed above the barrier, and a series of tests compared movement of the gobies downstream with the barrier on and off.
No live gobies were found downstream in the tests with the barrier operating at prescribed settings. The barrier was judged functional for preventing downstream movement of round gobies.
