| dc.description.abstract | A wide variety of variants of the OMP have been evaluated. The aim of the variations was to try and produce narrower probability intervals for the resource recovery statistics (B(16/06) values). Variations that were attempted include: • Alternate values of 1 f and 2 f (relative weighting factors for trap, hoop and FIMS CPUE in the OMP) • Alternate values of p (see Eqn 1 in ASWS/JUL07/WCRL/MP/1 ) • Alternate levels of “capping” of input data (see pg section iv of ASWS/JUL07/WCRL/MP/1) • Alternate forms of the somatic growth “response” term (see pg 16 of ASWS/JUL07/WCRL/MP/1 • Limits on the extent of large inter-annual changes in the input indices, which would seem implausible • Maintaining future somatic growth rate constant (and removing the somatic growth term from OMP) in an attempt to improve the OMP performance based on future recruitment variability only. | en_ZA |
