Preliminary tag-recapture based population assessment of Antarctic toothfish in Subarea 48.4
Abstract: The stock of Antarctic toothfish (D. mawsoni) in CCAMLR subarea 48.4 is estimated from ... tagging returns to be 982 tonnes in 2018. Applying the CCAMLR agreed precautionary assumption of average ... biomass across the time series and harvest rate of γ = 0.038, implies a 2018/19 yield of 37 tonnes ... , unchanged from the 2017/18 catch limit. Historically, a precautionary approach has been applied in treating ...
