4. Investigation of potential biases in the assessment of Antarctic toothfish in the Ross Sea fishery using outputs from a spatially explicit operating model

   . Conceptually this assumption implies either that tagged and untagged fish mix equally in the population, or ... that fishing effort for recaptures is distributed in proportion to the underlying abundance. Neither of ... these conditions are likely to occur in practice, and violation of this assumption may lead to bias. In ... this paper we investigate such potential biases in the assessment of Antarctic toothfish in the Ross ...
