Cod Population Structure Symposium

Primary tabs

Cod Population Structure and New England Fisheries: Furthering our understanding by integrating knowledge gained through science and fishing


This symposium will provide an opportunity to explore and discuss the current understanding of the stock structure of cod in the Gulf of Maine and southern New England regions (as well as nearby Canadian waters of Georges and Brown Bank and the Scotian Shelf). Participants will synthesize prior knowledge and new scientific findings with the on-the-water experience and observations of recreational and commercial fishermen. The symposium will contribute information to the newly formed Atlantic Cod Stock Structure Working Group focused on re-evaluating cod stock structure in U.S. waters.


  • Present recent findings among regional scientists studying Atlantic cod stock structure in US and adjacent Canadian waters
  • Capture insight and feedback from fishermen on what is being observed on the  water to incorporate into the developing model by researchers
  • Identify areas of common ground in the understanding of cod population structure and areas of remaining uncertainty
  • Learn about a series of alternative management options that may be considered in the future to accommodate the evolving understanding of cod stock structure
