Proceedings of the Newfoundland and Labrador Regional Atlantic Cod Framework Meeting: Reference Points and Projection Methods for Newfoundland cod stocks; November 22-26, 2010
Chairperson: Joanne Morgan
Editors: M.B. Davis and K. Skanes
Summary
The purpose of this workshop was two-fold. The first objective was to discuss methodologies for the determination of reference points for Newfoundland cod stocks; and the second was to solicit views on methodologies for carrying out projections on Newfoundland cod stocks. Various methods were put forward and discussed/peer-reviewed during the meeting by participants from DFO Science in the Newfoundland and Labrador, Maritimes, and Quebec Regions. Participants from DFO Fisheries and Aquaculture Management provided the appropriate guidance for potential future applications (e.g. application of the Precautionary Approach; Recovery Potential Assessments) of the discussed approaches.
The main focus of the reference point portion of the meeting was the determination of a limit reference point (LRP) for 2J+3KL (northern) cod. In addition the existing LRP for 3Ps and 3NO cod were examined. Some guidance was also given on the setting of removal reference, upper stock reference and target reference points. The projection portion of the meeting agreed on how to treat the inputs and stochasticity in long term projections and on how to combine stocks to form designatiable units (DUs).
