Stock assessment of the Australian east coast grey mackerel (Scomberomorus semifasciatus) fishery.Tools Bessell-Browne, P., Lovett, R., Leigh, G., O'Neill, M.F. and Campbell, A. (2019) Stock assessment of the Australian east coast grey mackerel (Scomberomorus semifasciatus) fishery. Technical Report. State of Queensland.
AbstractThis stock assessment used an age structured model with a yearly time step and age based selectivity to estimate the population size and sustainable harvest limits for Queensland east coast grey mackerel. Separate models were assessed for the north-east and south-east stocks. Data inputs included total harvest, standardised catch rates, age and length structures. For both stocks, unfished biomass was relative to 1960-61, before substantial fishing pressure began.
