    The stock of Antarctic toothfish (D. mawsoni) in CCAMLR Subarea 48.4 is estimated from tagging returns to be 979.3 tonnes in 2017. Applying the CCAMLR agreed precautionary assumption of average biomass across the time series and harvest rate of γ = 0.038, implies a 2017/18 yield of 37 tonnes compared to the 2016/17 catch limit of 38 tonnes.
