Stock Status Update of Shrimp on the Eastern Scotian Shelf

Regional Peer Review – Maritimes Region

December 8, 2022
Virtual Meeting

Chairperson: Tara McIntyre

Context

The Northern or Pink Shrimp, Pandalus borealis, is the only shrimp species of commercial importance in the DFO Maritimes Region. The fishery consists of 28 DFO Maritimes Region-based licences, mostly less than 65 ft length overall, and 14 DFO Gulf Region-based licenses 65–100 ft length overall. All mobile licences have been under Individual Transferable Quotas (ITQs) since 1998. A competitive trap fishery with 14 licences is largely restricted to Chedabucto Bay. The fishery operates under an ‘evergreen’ management plan, which documents sharing agreements between fleet sectors. The first Eastern Scotian Shelf Northern Shrimp Framework Review occurred in 2015 (Hardie et al. 2018). Various assessment methodologies were reviewed and the continued use of the Traffic Light Approach was supported as the framework to assess the stock health. The status of Eastern Scotian Shelf Shrimp was last assessed during a science advisory process in December 2021 (DFO 2022).

Objectives

The objectives of this regional peer review process are:

• Assess the overall status of Eastern Scotian Shelf shrimp (Shrimp Fishing Areas 13–15) as of the fall of 2022, including stock abundance and exploitation rate.
• Provide stock status under the PA strategy and its established reference points to help describe the 2022 outlook in order to give the best available information for determining the harvest levels for the 2023 fishery season.
• Update descriptive information related to the fishery, survey, and biology of the target species.
• Provide advice on environmental variable and the impact on ecosystems and the target species.
• Report on the bycatch of non-target species in observed trips in the 2022 fishery, including the abundance of bycatch species relative to the amount of shrimp caught in the fishery that year and any notable changes in their occurrence relative to previous years.
• Review updated data sources and stock health indicators.
