Researchers develop new model to assess fish passage

Fishes, such as salmon, who must swim upstream to their birthplace to spawn are often impeded by obstacles like dams and roads that crisscross rivers and streams. A team of researchers from the University of Georgia and the U.S. Army Corps of Engineers Engineer Research and Development Center has developed a new model that could help environmental managers determine the most cost-effective way to improve the fishes' chances of reaching spawning grounds. Their work was recently published in the journal Ecological Applications.
