Snow Crab Abundance and Biomass Estimates (Commercial Crab and Mature Female) in the Southern Gulf of St. Lawrence

PURPOSE: These data have been updated following a Canadian Science Advice Secretariat (CSAS) Regional Science Advisory Process. Associated publications are available in the citation section below or will be posted on the Fisheries and Oceans Canada (DFO) Science Advisory Schedule as they become available.

DESCRIPTION: Provide a record of commercial and mature female snow crab abundance and biomass in the southern Gulf of St. Lawrence. Female snow crab represents an index of reproductive stock.

Snow crab in the southern Gulf are treated as a single stock in the annual assessments. Abundance and biomass estimates for the commercial and female reproductive stock are produced using kriging, a type of spatial analysis. The time series starts in 1997.

USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian. xx
