Using outputs from spatial population models of Antarctic toothfish in the Ross Sea region to investigate potential biases in the single population model
Abstract: We present a method to evaluate potential biases and uncertainty in the tagging ... assumptions of the stock assessment for Antarctic toothfish in the Ross Sea region using spatially explicit ... operating models. The method allows investigation of potential biases and uncertainty in the assumptions of ... spatial distribution and fish mixing used in the standard stock assessments for the Ross Sea region (and ...
