Mussel Study on the Dragon
|
On April 5 an elite group of scientists suited up and plunged into the Dragon Run in search of mussels. It was a beautiful day but the water was cold and gasps could be heard with initial exposure to the chill. Dry suits, hoods, gloves and snorkels were the dress of necessity, as the experts explored river bottom at the Mascot crossing and at Big Island. One large black species was found in abundance, Elliptio complanta, common name Eastern Elliptio. A more intensive search to determine what additional species might be found was determined to be warranted. A new record of a tiny snail is also expected. The clarity and purity of Dragon Run waters is thought to be partially a result of the presence of mussels, which like oysters are filter feeders and clean out suspended particles. Those participating in the
survey from the US Fish and Wildlife Service were biologists Cindy Kane, John
Schmerfeld, Jess Jones, Sumalee Hoskin, Brian Evans, and Will Smith. From
Virginia Polytechnic Institute and State University were renowned mussel expert,
Richard Neves, and Bill Henley, and from the Virginia Department of Game
and Inland Fisheries, was state malacologist, Brian Watson. |
