Proceedings of the Pacific regional peer review of Candidate Limit Reference Points for Pacific Herring in British Columbia using a Closed-loop Simulation Modelling Approach; May 27-28, 2015
Chairperson: Nicholas Duprey
Editor: Lesley MacDougall
Summary
These Proceedings summarize relevant discussions and key conclusions that resulted from the Canadian Science Advisory Secretariat (CSAS) Regional Peer Review (RPR) meeting of May 27-28, 2015, held in Nanaimo, British Columbia to review the working paper titled, “Candidate Limit Reference Points for Pacific Herring in British Columbia using a Closed-loop Simulation Modelling Approach”.
In-person and web-based participants included current and retired Fisheries and Oceans Canada (DFO) Science and Fisheries Management staff, First Nations representatives, representatives from the Province of British Columbia, Alaska Department of Fish and Game, members of commercial and recreational fishing sectors, environmental non-government organizations, and academia.
The working paper presented the results of a closed – loop simulation modelling approach to evaluate the performance of a select group of management procedures relative to candidate limit reference points (LRPs). The current British Columbia (BC) Pacific Herring harvest strategy does not include a clear set of biological LRPs that reflect the conservation requirements as described in the “Fishery Decision Making Framework Incorporating the Precautionary Approach”; part of DFO’s Sustainable Fisheries Framework. This closed – loop simulation model, and the selected management procedures, were presented as a proof of concept for the intended purpose of identifying and evaluating LRPs and informing the renewal of the management framework for BC Pacific Herring in accordance with Canada’s Sustainable Fisheries Framework. Additional meeting objectives were to: describe operating model scenarios for each of the five major BC Pacific Herring stocks; assess the suitability of the modelling approach for simulating environmental forcing factors and exploring the performance of existing and alternative management procedures at avoiding candidate LRPs; and discuss considerations for the selection of biologically – based LRPs including providing advice on subsequent science initiatives required to advance renewal of the management framework for BC Pacific Herring. Note that advice was not expected, nor provided regarding the selection of one specific management procedure or LRP.
The conclusions and advice resulting from this RPR process will be provided in the form of a Science Advisory Report, and will be used to inform the ongoing renewal of the management framework (development of objectives, data collection, harvest control rules) for BC Pacific Herring. The Science Advisory Report and supporting Research Document will be made publicly available on the Canadian Science Advisory Secretariat (CSAS) Website.
