Courses

This course provides instruction and demonstration of a wide range of methods used to identify population structure of fishery resources, including life history traits, morphology, environmental signals, genetics, dispersal modeling and marking techniques. Methodological reviews include historical development, benchmark case studies, critique of current issues, interdisciplinary synthesis and prescriptions for the best practice for stock identification. Applications in fisheries science will be described to promote an interdisciplinary approach to stock identification.

Research for and preparation of doctoral dissertation proposal. The dissertation proposal must provide a thorough survey of the research activities in the research topic area and it must present original and innovative research ideas and preliminary results as well as a defined research scope and directions. PhD students must have passed this course before registering for doctoral dissertation research credits. Graded P/F.

Investigations of a fundamental and/or applied nature representing an original contribution to the scholarly research literature of the field. PhD dissertations are often published in refereed journals or presented at major conferences. A written dissertation must be completed in accordance with the rules of the Graduate School and the School for Marine Science and Technology. Admission to the course is based on successful completion of the PhD comprehensive examination and submission of a formal proposal endorsed by the student's graduate committee and submitted to the SMAST Graduate Program Director.

Steve Cadrin has been a stock assessment scientist for over 30 years, previously with the National Marine Fisheries Service’s Northeast Fisheries Science Center in Woods Hole, Massachusetts Marine Fisheries, and New York Department of Environmental Conservation.  His accomplishments include the advancement of stock assessment methods for a wide range of invertebrate and finfish species, fishery management advice for regional, national and international fisheries, and global leadership in evaluating geographic stock structure and modeling spatially complex populations.  He has chaired several regional, national and international working groups and committees and has convened workshops, symposia, and conferences for the International Council for the Exploration of the Seas, National Marine Fisheries Service, New England Fishery Management Council, American Fisheries Society and the Northeast Fish and Wildlife Conference. Steve received the American Fisheries Society’s Award for Outstanding Marine Fishery Biologist for sustained excellence in marine fishery biology, the University of Massachusetts Dartmouth’s 2021 Scholar of the Year Award, and the Joint Ocean Commission Initiative’s Excellence in Mentoring Inaugural Award. He is also Past President of the American Institute of Fisheries Research Biologists.  His teaching and research agendas focus on population modeling, stock identification, fisheries management, collaborative research with fishermen, and application of advanced technologies for fishery science.
