Proceedings of the PSARC Invertebrate Subcommittee Meeting, June 17-19, 2003 : Compte rendu de la réunion du sous-comité des invertébrés du CEESP, 17-19 juin 2003

The Subcommittee recommended the continued use of the time series model to assess GSU stocks in British Columbia in conjunction with the Bayesian model and supported the range of target yield options outlined in the paper. [...] The Subcommittee recognized that the nature of the shrimp trawl fishery had changed over time and the ability of the fleet to target specific size and shrimp species had increased. [...] During the introductory remarks the objectives of the meeting were reviewed, and the Subcommittee accepted the meeting agenda. [...] The rationale behind using the limit reference point of 50% of the virgin biomass estimates calculated from the Gulland model was questioned by the Subcommittee and it was suggested that the same rule may not apply to all populations. [...] The reviewer noted that the Bayesian method incorporates both the uncertainties in CPUE and the catch reported in the initial nine years of information, as well as incorporates the data collected from fishery independent surveys.
