Quantifying uncertainty in the Chapman mark-recapture estimate of abundance
Abstract: In New and Exploratory fisheries for toothfish, mark-recapture plays a critical role to estimate biomass in the initial stage of developing an assessment. This short paper describes the use of the R package tagr to obtain Petersen / Chapman estimates of abundance. The package implements

An updated assessment of unicorn icefish (Channichthys rhinoceratus) in Division 58.5.2, based on results from the 2015 random stratified trawl survey
Abstract: The annual Random Stratified Trawl Survey was undertaken within Division 58.5.2 during May 2015. Recent work which is presented here has allowed for many of the biological parameters of Channichthys rhinoceratus to be updated from previous assessments (Constable et al. 1998) and many

Exploring age and growth dynamics of a historically overfished Sub-Antarctic fish species: The grey rockcod (Lepidonotothen squamifrons) in the vicinity of Heard Island and McDonald Island
Abstract: The grey rockcod (Lepidonotothen squamifrons) was fished to commercial extinction on the Kerguelen Plateau by unregulated fishing during the 1970s/80s. Since the mid-1990s little work has been performed to assess the status of this species within the Heard Island and McDonald Island

Spatial and temporal patterns of sperm whale (Physeter macrocephalus) depredation on Australian longline vessels in the Patagonian toothfish (Dissostichus eleginoides) fishery at Heard Island and McDonald Islands (CCAMLR Division 58.5.2)
Abstract: Incidence of odontocete depredation, involving sperm whales (Physeter microcephalus) and orcas (Orcinus orca) has been reported in nearly all of the Patagonian toothfish (Dissostichus eleginoides) longline fisheries in the Southern Ocean (Moir Clark and Agnew 2010, Tixier et al 2010,

Revised research plan for the exploratory longline fishery for Dissostichus spp. in Statistical Subarea 88.3 in 2015/16
Abstract: The subarea 88.3 is a large area contained from 105°W to 70°W where has been closed to directed fishing following the results of a Chilean survey activities in 1998 (SC-CCAMLR-XVII/BG/7). Previous three research surveys conducted by the New Zealand and the Russian flagged vessels since
