    The 2010 operational management procedure for the South African Merluccius paradoxus and M.?capensis resources
    (2010) Rademeyer, Rebecca A; Fairweather, T; Glazer, Jean Patricia; Leslie, R L; Butterworth, Doug S
    The algorithm for the 2010 Operational Management Procedure (OMP) to provide TAC recommendations for the South African Merluccius paradoxus and M. capensis resources is empirical. It combines an increase or decrease of the TAC in relation to a) the magnitude of recent trends in CPUE and survey abundance estimates for both species and b) the relative level of recent CPUE and survey abundance estimates compared to a target level. The basis for the associated computations is set out below, with the tuning parameters given in Table 1. Details of the computation procedures for the CPUE and catch data are provided in Appendix A, and for the survey estimates of Biomass in Appendix B.
