Stock Status Update of American Lobster in Lobster Fishing Area (LFA) 41

Regional Science Response Process – Maritimes Region

Chairperson: Tara McIntyre

Context

American Lobster (Homarus americanus) is found in coastal waters from Maryland to southern Labrador, with the major fisheries concentrated around Gulf of Maine and 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.
Lobster in Lobster Fishing Area (LFA) 41 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 stock assessment was conducted in September 2017 (DFO 2018) and was consistent with the assessment framework adopted in January 2017 (Cook et al. 2017).  The 2017 assessment was based on two primary indicators of stock status, commercial biomass from research vessel surveys and reproductive potential.  A suite of contextual indicators was also provided to show broad trends and ecosystem changes. 

This Update reports on the primary indicators only up to the end of the 2018 fishing season.
