Proposal to continue participation in the second year of the joint CCAMLR research survey to collect spatially stratified longline and bathymetric data in 88.2_A and 88.2_B in 2015/16
Abstract: Toothfish in SSRUs 882.A–B are currently managed as part of the Ross Sea region stock ... , but the stock structure and fish movement patterns are uncertain and more information is required for ... the management across all of the region. Recognising this requirement, the Scientific Committee ... endorsed two years of spatially stratified longline surveys in the northern region of SSRUs 88.2A–B (SC ...

Investigation of potential biases in the assessment of Antarctic toothfish in the Ross Sea fishery using outputs from a spatially explicit operating model
-recapture data, and rely on the assumption that tagged and untagged fish have constant probabilities of ... recapture regardless of the spatial distribution of releases or subsequent fishing effort for recaptures ... . 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 ...
