Cytotaxonomy of antarctic teleosts of the Pagothenia/Trematomus complex (Nototheniidae, Perciformes)
Polar Biology, 1992The interspecific relationships and taxonomy of 12 antarctic coastal Nototheniids (the Pagothenia/ Trematomus complex) are still under discussion. Here we present karyological data on eight species in hope that further cytogenetic data can help to clarify phylogenetic problems.

Ontogeny of vision in the Antarctic fish Pagothenia borchgrevinki (Nototheniidae)
Polar Biology, 1990Pagothenia borchgrevinki ranging in size from 63 to 245 mm were captured from beneath sea ice in McMurdo Sound by fishing and diver collection. Changes in ocular morphology with increasing body size were measured, and assessed in relation to ingested prey. Relative eye size was highest among smaller fish (

The osteological development of nine species of Nototheniidae (Perciformes: Notothenioidei)
1997The osteological development of nine species of nototheniids was investigated. All the species in general are characterized by the similar sequence of appearance of bones, except for Pleuragramma antarcticum. It is shown that the latest appearing bones are as a rule reduced in more derived species of the nototheniids and/or in advanced families of the ...

Diversified feeding strategies of Pleuragramma antarctica (Nototheniidae) in the Southern Ocean
Polar Biology, 2019The Antarctic silverfish Pleuragramma antarctica is a plankton feeder playing an important role at midtrophic level in High Antarctic ecosystems. Over years, a reasonable bulk of information has been collected on the trophic ecology of the species, nevertheless there are several aspects that still deserve full elucidation.

Cytogenetic and Genome Research, 2002
The results of a cytogenetic study conducted with banding and in situ hybridization techniques using ribosomal and telomeric probes on various species belonging to three families (Bathydraconidae, Channichthyidae and Nototheniidae) of the perciform suborder, Notothenioidei, are reported.

Confirmation of neutral buoyancy in Aethotaxis mitopteryx DeWitt (Notothenioidei: Nototheniidae)
Polar Biology, 2006Aethotaxis mitopteryx is a nototheniid species with a circum-Antarctic distribution in the Southern Ocean. We present new locality records, buoyancy measurements, and morphometric data on five A. mitopteryx specimens collected from the Bransfield Strait. Our analyses demonstrate that A. mitopteryx is neutrally buoyant.

Planktivory in Pagothenia borchgrevinki (Pisces: Nototheniidae) in McMurdo sound, Antarctica
Polar Biology, 1987Specimens of the Antarctic fish P. borchgrevinki were collected from just beneath the sea-ice in McMurdo Sound over the period 8 November to 6 December, 1985. The stomach contents of 200 fish were analysed and compared with the co-occurrence of the prey species in the plankton.

Mitochondrial DNA, 2014
The complete sequence of the mitochondrial genome of Pleuragramma antarcticum was obtained from the assembled genome data. The complete sequence was determined to be 18,460 bp in length, containing 13 protein coding genes, 22 tRNA genes, 2 rRNA genes, 2 control regions and a repeat.

Osteological development of the Antarctic silverfish Pleuragramma antarcticum (Nototheniidae)
1994The paper presents a study of the osteological development of the Antarctic silverfish Pleuragramma antarcticum Boulenger (Nototheniidae). In comparison with other investigated nototheniids the development and ossification of the basioccipital and exoccipital were found to occur late in the neurocranium.
