Proceedings of the Regional Peer Review of the Stock Assessment of St. Mary’s Bay Longhorn Sculpin (Myoxocephalus octodecemspinosus) Fishery; March 3, 2020
Chairperson: Lottie Bennett
Editor: Lottie Bennett
Summary
A regional peer review of the stock assessment of the St. Mary’s Bay Longhorn Sculpin fishery was held on March 3, 2020, at the Bedford Institute of Oceanography in Dartmouth, Nova Scotia to review available information for evaluating the sustainability of the fishery and to identify indices to monitor the fishery. Participation in this meeting included Fisheries and Oceans Canada (DFO) and the fishing industry.
The main indicator used to assess stock status is a Limit Reference Point (LRP) based on 40% of the 1999-2019 Catch Per Unit Effort (CPUE) time series. A smoothed CPUE index, calculated using a 3-year moving median to reduce variability in the time series, was used to determine the current level of relative abundance in relation to the LRP. Additional indicators that could be used to monitor/assess stock status in future assessments were proposed. These indicators support the conclusion that the stock is now approaching the Cautious/Critical Zone boundary.
This proceedings document includes a summary of the presentations and is a record of the meeting discussions and conclusions. A Science Advisory Report and Research Document resulting from this meeting will be published on the Fisheries and Oceans Canada (DFO) Canadian Science Advisory Secretariat’s (CSAS) Website as they become available.
