Stock Assessment of Snow Crab in Maritimes Region

Regional Peer Review - Maritimes Region

February 26-27, 2024

Dartmouth, NS

Chairperson: Michelle Greenlaw

Context

Snow Crab (Chionoecetes opilio, O. Fabricius) is a subarctic species with a distribution from northern Labrador to near the Gulf of Maine. Snow Crab has been a dominant macro-invertebrate in the Scotian Shelf ecosystem since the decline of the groundfish during the late 1980s to early 1990s. They are observed in large numbers in deep, soft-bottom substrates ranging from 60–280 m water depths and at temperatures generally less than 6 °C. Scotian Shelf Snow Crab are in the southern-most extreme of its spatial distribution in the Northwest Atlantic.

The Snow Crab fishery on the Scotian Shelf has been in existence since the early 1970s. It occurs annually throughout the year dependent upon the Crab Fishing Area (CFA). In 2005, many CFAs and subareas were merged with the resulting divisions being North-Eastern Nova Scotia (N-ENS; formerly CFAs 20-22), South-Eastern Nova Scotia, S-ENS; formerly CFAs 23, 24), and Northwest Atlantic Fisheries Organization (NAFO) Division 4X. In support of the fishery, Fisheries and Oceans Canada (DFO) Maritimes Fisheries Management Branch requested that DFO Science Branch assess the status of the resource for the coming fishing season. The last Snow Crab Science Advisory Meeting was completed in March 2023.
