Joseph Zydlewski

Sampling American shad on the Penobscot River.

Education

  • Ph D University of Massachusetts 1997
  • BS Bates College 1990

Biography

Joe joined the Maine Cooperative Fish and Wildlife Research Unit in 2004 as Assistant Unit Leader, coming from the USFWS Columbia River Fisheries Program Office. He is an Associate Professor in the Department of Wildlife, Fisheries, and Conservation Biology and cooperating faculty in the School of Biology and Ecology and the School of Marine Sciences at the University of Maine, Orono.

Research Interests

Joe's work centers on the study of fish movements and migrations. Many vital fisheries issues in the northeast United States are dependent upon a rigorous understanding of life history expression. He has effectively addressed both basic and complex management questions in innovative ways, developing a program which includes three main themes: i) Connectivity and River Restoration ii) Physiology and Behavior of Migration , and iii) Species interactions. As a critical part of his position, Joe's work is responsive to the requests of MCFWRU cooperators (e.g. Maine Department of Inland Fisheries and Wildlife, the University of Maine’s Department of Wildlife Ecology and US Fish and Wildlife Service).

Teaching Interests

As part of his appointment to the graduate faculty at the University of Maine through the MCFWRU, Joe provides graduate instruction in the form of formal courses (e.g. "Movements and Migration" and "Quantitative Freshwater Fisheries Ecology"), directing independent studies of selected topics (fisheries science, migration biology), and interacting with graduate students. Joe serves on numerous committees as degree program advisor, co-advisor, or committee member.
