SEINE SAMPLE: Maine Department of Marine Resources employees James Beaudry, left, Josh Noll and Jason Bartlett examine fish they collected Tuesday in a seine net at the confluence of Worromontogus Stream and the Kennebec River in Randolph.  The scientists were sampling juvenile fish that are born in the River and its tributaries but reside in the Atlantic, according to Bartlett, such as Striped Bass.  The net survey is conducted six times a year on the Kennebec River between Hallowell and Phippsburg.
