STURGEON HUNTERS: Maine Department of Marine Resources biologists Gail Wipplehauser, left, Jason Valliere and Jason Bartlett search for SNAP Monday on a computer they used to track the fish with a sonar while floating on the Kennebec River between Gardiner and Randolph. The scientists were hoping to determine why the shortnose and Atlantic sturgeon tagged with transmitters had not migrated to their winter terrain in the Kennebec River in Richmond, according to Wipplehauser. “They seem to be roaming this year,” she said of fish that reach up to nine feet in size. The sonar study of shortnose, an endangered species, and Atlantic sturgeon is funded by the National Oceanic Atmospheric Administration, a federal agency.
