This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high abundance of prerecruits (R-3 and R-2) observed in the 2002 trawl survey could increase the level of recruitment to the fishery for the next two or three years. [...] In 1998, landings were 289 t, which corresponds to 70% of the total quota set at 411 t. The fishery was closed three times during the fishing season because of the high percentages of soft-shelled crabs in the catches and the low commercial quality of landed crabs. [...] The mean CPUE of the fleet at year (i) corresponds to the ratio of total catches from sales slips (where available) or the fishermen's logbooks (yi) and the corresponding number of trap hauls (thi) reported in the logbooks: CPUEi = ∑yi/∑thi. [...] It was also decided at the last RAP meeting (Anonymous, 2001) that the 2000 biomass estimate from the 1999 trawl survey was not considered to be reliable due to the malfunction of the Netmind sensors and the difficulty to calculate the swept area by the trawl. [...] The color of the eggs of mature females and the color of the gonads of immature females were noted.

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.
