University of New England researchers caught an unexpected shortnose sturgeon while studying Atlantic sturgeon in the Saco River. The Atlantic sturgeon had officially disappeared from the Saco River 100 years ago.  James Sulikowski, assistant professor of marine sciences, and his students have been studying Atlantic sturgeon in the Saco River since catching one in 2007. The rarer shortnose sturgeon had never been found in the Saco River.
