List of MSF species/taxa considered in this report. The table shows the categories and the species/taxa that they include, as specified in the Management Plan (PIRSA 2013). Also shown are the gear types for which annual targeted catch, effort and CPUE are reported for each species. ....... 2 Table 1.2. Allocation triggers for the primary species of the Marine Scalefish Fishery. The table shows the percentage of the commercial allocation for each species to the various commercial fisheries that contribute to the total commercial catch. It also shows the trigger reference points for each of Triggers 2 & 3 for each fishery. Note that when the commercial allocation is >95%, no trigger limits are set. Fisheries are identified as MSF = Marine Scalefish Fishery, SZRL = Southern Zone Rock Lobster Fishery, NZRL = Northern Zone Rock Lobster Fishery, MISC = Miscellaneous Fishery, LCF = Lakes and Coorong Fishery, GSVP = Gulf St. Vincent Prawn Fishery, SGP = Spencer Gulf Prawn Fishery, WCP = West Coast Prawn Fishery. ..................................................... 4 Table 3.1a Comparisons between performance indicators and limit reference points for King George whiting. ............................................................................................................................................... 9 Table 3.1b Comparison of catches of King George whiting (tonnes) and relative contribution to total catch (percentage) by the different commercial sectors that reported taking King George whiting in each year between 2008/09 and 2012/13. ........................................................................................... 9 Table 3.1c Comparisons between the catches of King George whiting by the different commercial sectors in 2012/13 with allocation trigger limits specified in the Management Plan (PIRSA 2013), based on data presented in Table 3.1b. ............................................................................................... 9 Table 3.2a Comparisons between performance indicators and limit reference points for snapper........... 11 Table 3.2b Comparison of catches of snapper (tonnes) and relative contribution to total catch (percentage) by the different commercial sectors that reported taking snapper in each year between 2008/09 and 2012/13......................................................................................................................... 11 Table 3.2c Comparisons between the catches of snapper by the different commercial sectors in 2012/13 with allocation trigger limits specified in the Management Plan (PIRSA 2013). ............................. 11 Table 3.3a Comparisons between performance indicators and limit reference points for southern garfish. .......................................................................................................................................................... 13 Table 3.3b Comparisons between the catches of southern garfish by the different commercial sectors in 2012/13 with allocation trigger limits specified in the Management Plan (PIRSA 2013).
