Sensitivity of the stock assessment for the Antarctic krill fishery to time‐varying natural and fishing mortality

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 ...

The impact of predation by marine mammals on patagonian toothfish longline fisheries.

PLoS ONE, 2015
Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss.

Whole‐genome resequencing improves the utility of otoliths as a critical source of DNA for fish stock research and monitoring

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.

Two new species of Acanthocotyle Monticelli, 1888 (Monogenea: Acanthocotylidae), parasites of two deep-sea skates (Elasmobranchii: Rajiformes) in the South-East Pacific

Parasites & Vectors, 2019
Background Parasites of deep-sea fishes from the South-East Pacific (SPO) are poorly known. Of c.1030 species of fish found in this area, 100–150 inhabit the deep-sea (deeper than 200 m).

Reproductive aspects of the Patagonian toothfish (Dissostichus eleginoides) off southern Chile

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%).
