Assessment of snow crab (Chionoecetes opilio) in the southern Gulf of St. Lawrence (areas 12, 19, 12E and 12F) and advice for the 2016 fishery / : Snow crab sourthern Gulf

The peak landing of the entire history was in 2005 at 36,118 t. The landings of snow crab from the southern Gulf of St. [...] In the 2015 trawl survey, geographic concentrations of commercial-sized adult males were located in Bradelle Bank, in Shediac valley, in Chaleur Bay, the central and in the southern parts of the Magdalen Channel and in the southeastern part of the sGSL (Figure 7). [...] Lawrence is calculated as the ratio between the catch of the fishery in the year of the assessment and the commercial biomass estimated from the trawl survey in the previous year. [...] Total mortality is calculated as residual biomass estimated from the survey in the year of the assessment divided by the biomass available to the fishery as estimated in the previous year’s survey. [...] Over the time series, the estimated commercial biomass from the survey was 29.2% higher than the sum of the residual biomass and the landings of the following year.
