Dartmouth, NS

Chairperson: Kristian Curran

Context

American Lobster (Homarus americanus) is found in coastal waters from Maryland to southern Labrador, with the major fisheries concentrated in the Gulf of Maine to the Gulf of St. Lawrence areas. Though Lobster is most common in coastal waters, they are also found in deeper, warm water areas of the Gulf of Maine and along the outer edge of the continental shelf from North Carolina to Sable Island on the Scotian Shelf. Lobster in Lobster Fishing Area (LFA) 33 is assessed on a multi-year assessment schedule, with stock framework and assessment science advisory processes conducted approximately every five years and stock status updates conducted in the interim years. The last framework and assessment reviews were conducted in 2018 (Cook 2020; DFO 2020). The 2018 framework presented a suite of primary, secondary, and contextual indicators for use as stock assessment indicators, as well as upper stock and limit reference indicators. The last interim stock update was conducted in 2022 (DFO 2023).

This interim stock update reports on the primary and secondary indicators to the end of the 2023-2024 fishing season.

Objectives

The objectives of this process are:

• Update the values for the primary stock status indicators adopted during the 2018 Stock Framework Regional Advisory Process to report on the stock status of the LFA 33 Lobster stock to the end of the 2023-2024 season.
• Evaluate the primary indicators against the reference points for LFA 33.
• Report on secondary indicators adopted during the 2018 Stock Framework Regional Advisory Process.
