Daniel C. Josephson

M.S. - Virginia Tech - 1983
B.S. - Cornell University - 1979
A.S. - Jamestown Community College - 1977

Daniel Josephson joined the Department of Natural Resources in 1983. He conducts applied fishery research as a staff member of the Adirondack Fishery Research Program and manages the Little Moose Field Station near Old Forge, New York. His research focuses on ecosystem processes that influence coldwater fisheries; with primary interest in native salmoinds of the Adirondack Mountain region including brook trout, lake trout, and round whitefish.

Research

His current research examines (1) the role of movements and food webs in sustaining salmonid populations, (2) the impacts of acid precipitation and non-native fish introductions on native fish populations, and (3) the restoration of brook trout and round whitefish populations in Adirondack waters.
