Copeia, 1964
Pagothenia antarctica is determined to be a valid genus and species. The genus is characterized by the absence of an upper lateral line and the peculiar condition of the cephalic lateral line canals. The fenestra of the pectoral girdle is enclosed by the scapula.

Four independent molecular data sets were sequenced in order to solve longstanding phylogenetic problems among Antarctic teleosts of the family Nototheniidae. The anatomical data of Balushkin (2000) were also coded into a matrix of 106 characters in order to test the parsimony of his taxonomic conclusions.

Mitochondrial DNA Part A, 2014
The complete sequence of the mitochondrial genome of Notothenia coriiceps was obtained by genome assembly. The complete sequence was determined to be 18,347 base pairs in length and to contain 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 control regions. Of the thirteen protein-coding genes, two genes (cox1 and atp6) had GTG start codons,

Fish species richness in the Southern Ocean accounts for approximately 2 % of the world’s ocean species, with more than 370 species registered and several awaiting for formal description. Here we explore on the use of DNA barcoding to discriminate fishes from Antarctic Peninsula by compiling our results and placing them into a comparative framework ...

Three specimens of Paranotothenia magellanica (Forster, 1801) were caught in the coastal region of Buenos Aires Province, Argentina, representing the northernmost known record of the species. Morphological and meristic characteristics, as well as a photograph of one specimen, are included in the study. P.

Lymphomyeloid organs of the Antarctic fish Trematomus bernacchii were studied with the aim of analysing some morphological aspects related to adaptation to low environmental temperature. The thymus of T. bernacchii was flattened, incompletely lobated and scarcely regionalised. It was filled by lymphoid elements intermingled with stromal elements.

Nine spcies of notothenioid fishes were captured near the southern limit of their range in ice covered McMurdo Sound, Antarctica. Stomach contents were examined using an occurrence method. Fishes were present in the diets of 8 of 9 species;Dissostichus mawsoni andGymnodraco acuticeps were predominantly piscivorous.Pleuragramma antarcticum was the most ...

Durant l’été 1996, des prélèvements d’ichtyoplancton ont été effectués dans la zone côtière de Terre Adélie. Quatre-vingt-dix-neuf pour cent des larves appartenaient à Pleuragramma antarcticumBoulenger, 1902. Des études histologiquesont été effectuées afin de déterminer leur condition physiologique.

The diet of three Patagonotothen species was investigated from the bycatch of near-bottom trawls for squid on the southern Falkland Island shelf. Patagonotothen ramsayi had a moderately diverse diet that was mostly zooplankton, especially amphipods, but included benthos and discards from the fishery, especially squid. P.
