Stock status in 2021 and fishery advice for 2022 for Snow Crab from the Southern Gulf of St. Lawrence

Regional Advisory Meeting – Gulf Region

January 25-27, 2022
Virtual Meeting

Chairperson: Amélie Rondeau

Context

In support of the DFO Fisheries and Aquaculture Management Sector's request for science advice, the Science Branch, Gulf Region, is undertaking the annual peer review of the stock status of the snow crab (Chionoecetes opilio) population in the southern Gulf of St. Lawrence (sGSL). Recent peer reviews have highlighted that some population indices from the 2019 and 2020 surveys were likely overestimated relative to previous surveys. One likely factor is an extended period of unaccounted for trawling that occurred during the trawl haul in the 2019 and 2020 surveys. Another issue identified was the practice of relocating trawl stations when the trawl was damaged, which led to a shift of these sampling stations to more trawlable areas over time opening the door to a bias on population indices.

Objectives

To develop peer-reviewed science advice for the management of the snow crab fishery in the sGSL biological unit for the 2022 fishing season.
