Update of the fishery indicators for the rock crab (Cancer irroratus) in the southern Gulf of St. Lawrence: Fs70-7/2016-053E-PDF

"Landings of rock crab from the directed fishery have decreased between 2011 and 2015, consistent with the decrease in the number of fishing trips. Catch rates varied in recent years according to the LFA, with high values in 2015 for LFAs 23 and 25 but in the lower range for LFAs 24 and 26A. Contrasting patterns have been observed from the rock crab settlement index, with very low abundance values in the highly fished areas (LFAs 25 and 26A) and the highest values in LFA 24 where directed fishing activities are marginal and catch rates are at their lowest. The assessment of the rock crab fishery relies on a very limited number of indicators that are all fishery-dependent. Fishery data are obtained through several unrelated processes that increase the chance of data errors and result in delays in data availability. It is paramount that information from mandatory logbooks is complete and accurate. Only preliminary data for 2015 were available for this update"--Conclusions, p. 7.
