The Arrangement of the Peripheral Olfactory System of Pleuragramma antarcticum: A Well-Exploited Small Sensor, an Aided Water Flow, and a Prominent Effort in Primary Signal Elaboration

open access: yesAnimals, 2022
The olfactory system is constituted in a consistent way across vertebrates. Nasal structures allow water/air to enter an olfactory cavity, conveying the odorants to a sensory surface.

Unexpected Fine-Scale Population Structure in a Broadcast-Spawning Antarctic Marine Mollusc [PDF]

open access: yes, 2012
Several recent empirical studies have challenged the prevailing dogma that broadcast-spawning species exhibit little or no population genetic structure by documenting genetic discontinuities associated with large-scale oceanographic features.

Characterization of Four Liver-Expressed Antimicrobial Peptides from Antarctic Fish and Their Antibacterial Activity

open access: yesApplied Sciences, 2019
Liver-expressed antimicrobial peptides (LEAPs) are cysteine-containing cationic peptides. LEAP-1 and LEAP-2 are eight- and four-cysteine containing antimicrobial peptides found in animals, respectively.

Hibernation in an Antarctic Fish: On Ice for Winter

open access: yesPLoS ONE, 2008
Active metabolic suppression in anticipation of winter conditions has been demonstrated in species of mammals, birds, reptiles and amphibians, but not fish. This is because the reduction in metabolic rate in fish is directly proportional to the decrease in water temperature and they appear to be incapable of further suppressing their metabolic rate ...

Somatic energy content and histological analysis of the gonads in Antarctic fish from the Scotia Arc

open access: yesScientia Marina, 2005
Histological characteristics of the gonads and the energy contents of axial muscle, liver and gonads of Antarctic notothenioid fish collected during the LAMPOS (Latin American Polarstern Study) survey in April 2002 were analysed.

Dietary overlap in inshore notothenioid fish from the Danco Coast, western Antarctic Peninsula

open access: yesPolar Research, 2013
We carried out a dietary overlap analysis between notothenioid species by examining the stomach contents of more than 900 specimens collected in a fish assemblage at the Danco Coast, western Antarctic Peninsula, in the summer of 2000.

Eubrachiella antarctica (Quidor, 1906) (Copepoda)-levels of infection in selected fish species of the family Nototheniidae [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1999
Infection levels of six fish species-representing the family Nothoteniidae-with external parasite Eubrachiella antarctica (Quidor, 1906) (Copepoda) were studied in the season of 1978/79.

Effects of Fish Meal Replacement with Fermented Antarctic Krill Meal on Growth Performance, Body Color and Serum Biochemical Indexes of Koi Carp (Cyprinus carpio L.)

open access: yesProgress in Fishery Sciences, 2023
To investigate the effects of replacing fish meal with fermented Antarctic krill meal on growth performance, body color, and serum biochemical indexes of koi carp, 450 koi carp with an average body weight of (4.92±0.22) g were randomly divided into five ...
