Building a Shared Vision of Atlantic Cod Population Structure
and New England Fisheries


This symposium will present the preliminary findings of a 1-year interdisciplinary review of Atlantic cod stock structure, and provide an opportunity for participants to provide feedback on how these new findings relate to their on-the-water experience and observations. The symposium results will contribute information to the final report by the Atlantic Cod Stock Structure Working Group, which is focused on re-evaluating cod stock structure in U.S. waters.


  • Present the preliminary conclusions about cod stock structure from the perspective of 6 disciplines:
  1. spawning and early life
  2. genetic markers
  3. basic life history – abundance, growth, maturity
  4. external or internal ‘natural’ markers, shape, or coloration
  5. applied markers – both conventional and technology tags
  6. fisherman’s ecological knowledge
  • Capture insight and feedback from fishermen on what is being observed on the water to incorporate into the developing model by researchers
  • Compare status quo and alternatives regarding biologically-supported stock structure of cod in US waters to further identify areas of common ground in the understanding of cod population structure and areas of remaining uncertainty
  • Outline further steps forward for the working group and its products
