This report presents summaries of historic and recent landings data and the results of

stock assessments for brown crab, velvet crab and lobster, based on data collected

between 2009 and 2012.


Annex C: Velvet Crab per Recruit Analysis using Different Biological Parameters

Figure C 1: Male velvet crab biomass and yield-per-recruit ( YPR) predictions given changes from current effort by assessment area, data from 2009-2012. The YPR analysis was run using two different sets of biological parameters (Shetland and rest of Scotland).
