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%).

Reproductive aspects of the Patagonian toothfish (Dissostichus eleginoides) off southern Chile [PDF]
Latin American Journal of Aquatic Research, 2009 We present the results for the reproductive biology of Patagonian toothfish (Dissostichus eleginoides) caught off southern Chile from January to March and June to November 2006. A total of 10,896 specimens were measured (55-220 cm total length, TL) and sexed (7,049 males, 64.7%; and 3,847 females, 35.3%).

Estimaciones empíricas de mortalidad natural en el bacalao de profundidad (Dissostichus eleginoides Smitt, 1898) [PDF]
Revista de biología marina y oceanografía, 2007 The instantaneous natural mortality rate is estimated for toothfish (Dissostichus eleginoides) using empirical models, with the emphasis on an evaluation of the precision of the estimates. The results are compared with estimates obtained per age classes and obtained through an analytical model.

Ecography, Volume 2025, Issue 5, May 2025.Food‐webs are a major component of ecosystems and determinant for their functioning and structure. The food chain length (FCL) is a key feature of food‐webs and it is crucial for the resistance of the community to external stressors. The Southern Ocean (SO) food‐web is known for being short and dominated by an Antarctic krill Euphausia superba surplus,

Variation in wing and tail moult intensity in white‐chinned petrels
Journal of Avian Biology, Volume 2025, Issue 1, January 2025.The cost of moult is substantial, and the timing and intensity of flight feather moult can influence survival and fitness, especially in large, long‐winged species such as many seabirds. We explore variation in wing and tail moult in > 2400 white‐chinned petrels Procellaria aequinoctialis killed in fisheries off southern Africa to assess how they ...

Fisheries Management and Ecology, Volume 31, Issue 6, December 2024.Abstract The stock assessment model for the Antarctic krill fishery is a population model operating on daily timesteps, which permits modeling within‐year patterns of some population dynamics. We explored the effects of including within‐year patterns in natural and fishing mortality on catch limits of krill, by incorporating temporal presence of key ...

Molecular Ecology Resources, Volume 24, Issue 8, November 2024.Abstract Fish ear bones, known as otoliths, are often collected in fisheries to assist in management, and are a common sample type in museum and national archives. Beyond their utility for ageing, morphological and trace element analysis, otoliths are a repository of valuable genomic information.
