Towards a more selective Patagonian toothfish fishery

Marine and Fishery Sciences
The Patagonian toothfish (Dissostichus eleginoides) fishery in the South Atlantic Ocean, also known as the Argentine Sea, began in the mid-1980s. It is conducted using two types of demersal fishing gear: bottom trawl and bottom longline.

Satellite tagging confirms long distance movement and fast dispersal of Patagonian toothfish (Dissostichus eleginoides) in the Southwest Atlantic [PDF]

Frontiers in Marine Science
IntroductionTo better understand Patagonian toothfish (Dissostichus eleginoides) movement and habitat in the Southwest Atlantic, fifty popup satellite archival tags (PSATs) were deployed off Davis Bank on North Scotia Ridge between 2019 and 2020 on ...

First characterization of gastrointestinal culturable bacteria of Patagonian toothfish Dissostichus eleginoides (Nototheniidae) [PDF]

Revista de Biología Marina y Oceanografía, 2017
The Patagonian toothfish Dissostichus eleginoides is one of the most important fisheries from the Southern Ocean. The biology of this species is relatively well studied and some nutritionals issues have also been reported; however there is no information about the composition of the bacterial community of the gastrointestinal tract, which is essential ...

Food Components of the Muscle and Liver of Patagonian Toothfish Dissostichus eleginoides [PDF]

Korean Journal of Fisheries and Aquatic Sciences, 2011
Proximate compositions, fatty acid profiles, and total amino acid compositions of the muscle and liver of Patagonian toothfish Dissostichus eleginoides were studied. Lipid contents of the muscle and liver of the fish were 22.3% and 35.3%, respectively. Protein content was higher in the fish muscle (12.8%) than in the liver (8.7%).

Fishing yields and size structures of Patagonian toothfish (Dissostichus eleginoides) caught with pots and long-lines off far southern Chile Rendimientos de pesca y estructuras de tallas de bacalao de profundidad (Dissostichus eleginoides) capturados con trampas y espineles en el extremo sur de Chile

Latin American Journal of Aquatic Research, 2009
Herein, we compare information taken from the Patagonian toothfish (Dissostichus eleginoides) fishery operations carried out off the far southern coast of Chile (47°00'S-57°00'S) using pots (pots) and long-lines.

The effect of prey abundance and fisheries on the survival, reproduction, and social structure of killer whales (Orcinus orca) at subantarctic Marion Island. [PDF]

Ecol Evol, 2023
We tested whether the survival of killer whales (Orcinus orca) observed at Marion Island correlated with social structure and prey variables using multistate models of capture recapture data spanning 12 years. Survival was most strongly correlated with indices of social structure where higher sociality was associated with increased survival probability.

Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia. [PDF]

Conserv Biol
Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...
