This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Stock status of southern Gulf of St. Lawrence (sGSL) snow crab, Chionoecetes opilio, in 2021 is in the healthy zone based on the defined reference points for this stock, with an a commercially exploitable biomass of 80,950 t projected for 2022. The exploitation rate of the 2021 fishery was estimated at 31.5%, a relatively low value stemming from a 15% reduction in commercial biomass estimates made in response to concerns of over-estimation of stock indices during the 2019 and 2020 surveys. Fishery recruitment biomass is estimated at 62,473 t, while residual biomass was estimated at 19,144 t. Based on the harvest control rule, the commercial stock biomass index corresponds to a target exploitation rate of 40.96% resulting in a Total Allowable Catch (TAC) of 33,163 t for the 2022 fishery. Based on this catch option, a risk analysis indicates that there is a very low likelihood that the residual stock biomass would be below the limit reference point and a very high likelihood that the 2022 commercial stock biomass would be above the upper stock reference point. Mature female abundance remains high, though at lower levels than those observed in 2019 and 2020 and the population recruitment index is very high"--Abstract, page iv.

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.
