Length-at-age in juvenile Patagonian toothfish (Dissostichus eleginoides)
We used the otoliths from a sample of Dissostichus eleginoides pre-recruits, whose length density was distinctly polymodal, to see whether ages estimated by reading otoliths were congruent with the length modes observed. Length densities by age were compared graphically with the overall length density observed.

Twenty-First-Century Environmental Change Decreases Habitat Overlap of Antarctic Toothfish (Dissostichus mawsoni) and Its Prey. [PDF]
Antarctic toothfish are a commercially exploited upper‐level predator in the Southern Ocean, but knowledge on how Antarctic toothfish and its prey respond to environmental change remains incomplete. In this study, we employ the extended aerobic growth index to quantify changes in predator–prey viable habitat overlap in response to changes in ...

Indirect ecological interactions such as competition for resources between fisheries and marine predators have often been proposed but can be difficult to demonstrate empirically.

Southern elephant seals (Mirounga leonina Linn.) depredate toothfish longlines in the midnight zone. [PDF]
Humans have devised fishing technologies that compete with marine predators for fish resources world-wide. One such fishery for the Patagonian toothfish (Dissostichus eleginoides) has developed interactions with a range of predators, some of which are ...

Behavioural heterogeneity across killer whale social units in their response to feeding opportunities from fisheries. [PDF]
We used a unique long‐term monitoring dataset of a subantarctic killer whale population, spanning over 18 years, paired with statistical models, to assess variation in the way killer whale social units depredate fish catches on fishing gear in a commercial fishery that started in the 1990s.

The Patagonian toothfish fishery in Falkland Islands’ waters [PDF]
Abstract This paper examines and provides updated information on the status of toothfish stocks within Falkland Islands conservation zones and also provides a historical perspective of the fishery. The Patagonian toothfish has been taken as a bycatch since the trawl fishery was established in the Falkland Islands. However, specialised exploitation of

Modal and empirical lengths at sexual maturity for six deep-sea species in Ecuadorian oceanic waters
The objective of the present work was to establish modal lengths, empirical lengths at sexual maturity, and proportions of mature individuals of six deep-sea species from the bycatch of the experimental fishery for Patagonian toothfish (Dissostichus ...

Age and growth of blue antimora Antimora rostrata were examined in the waters off New Zealand and Macquarie Island (southwestern Pacific). Samples off Macquarie Island were collected from bycatch in the Patagonian toothfish longline fishery.

Characterizing Marine Heatwaves in the Kerguelen Plateau Region
Marine heatwaves (MHWs) are prolonged extreme oceanic warm water events. Globally, the frequency and intensity of MHWs have been increasing in recent years, and it is expected that this trend is reflected in the Kerguelen Plateau region.
