Age validation and growth of yolked larvae of Patagonotothen tessellata (Richardson, 1845) (Pisces: Nototheniidae) from the rocky littoral of the Beagle Channel, Argentina

Scientia Marina, 1999
Age and growth estimation of Patagonotothen tessellata larvae over the endogenous period was estimated by examining their otolith microstructure and the associated increment deposition rate.

Ontogenetic changes in the feeding strategy of Lepidonotothen nudifrons (Pisces, Nototheniidae) off the South Shetland Islands and the Antarctic Peninsula

Polar Research, 2017
The diet and feeding strategy of Lepidonotothen nudifrons off the South Shetland Islands and the Antarctic Peninsula, as well as their variation in relation to ontogenetic stage (juvenile–adult) and sampling area, were determined by stomach contents ...

Gill structure of the Antarctic fishes Notothenia (Gobionotothen) gibberifrons and Trematomus newnesi, Nototheniidae stressed by salinity changes and some behavioral consequences

Antarctic Record, 1995
In coastal Antarctic regions, melting and freezing affect water salinity. The aim of this study was to compare morphological changes of branchial epithelial cells in two species of Antarctic fishes, Notothenia (Gobionotothen) gibberifrons and Trematomus ...

First characterization of gastrointestinal culturable bacteria of Patagonian toothfish Dissostichus eleginoides (Nototheniidae)

, 2017
The Patagonian toothfish Dissostichus eleginoides is one of the most important fisheries from the Southern Ocean. The biology of this species is relatively well studied and some nutritionals issues have also been reported; however there is no information about the composition of the bacterial community of the gastrointestinal tract, which is essential ...
