Growth Patterns and Body Condition of Notothenioid Fish (Genus Trematomus) From the Antarctic Peninsula and Weddell Sea

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Growth patterns and body condition of 10 species of Trematomus (family Nototheniidae) collected off the Antarctic Peninsula and in the Weddell Sea during seven cruises carried out between 2002 and 2022 were estimated by length–weight relationships (LWRs) and relative condition factors (Krel).

Molecular systematics and taxonomic status of three latitudinally widespread nototheniid (Perciformes: Notothenioidei) fishes from the Southern Ocean.

Zootaxa, 2016
The taxonomic status of the three nototheniids, Lepidonotothen squamifrons, L. larseni and Gobionotothen marionensis from different localities in the Southern Ocean is re-evaluated at the DNA level.

Hematological and Physiological Changes in Rainbow Trout, Oncorhynchus mykiss, Exposed for 30 Days to Critical Low Temperature

Aquaculture Research, Volume 2024, Issue 1, 2024.
Rainbow trout (Oncorhynchus mykiss) acclimated to 9°C were exposed to 1.8 ± 1.0°C water for 30 days. Survival rate decreased by 8%, and RNA expression of the heat shock protein heatshock protein 90 (hsp90) gene was upregulated, indicating thermal stress. The fish exhibited no growth but lost weight (daily growth rate −0.17% ± 0.03%).

New nuclear markers and exploration of the relationships among Serraniformes (Acanthomorpha, Teleostei): The importance of working at multiple scales [PDF]

, 2013
International audienceWe explore the relationships within Serraniformes (Li et al., 2009) using a dense taxon sampling and seven nuclear markers. Six had already used been for teleost phylogeny (IRBP, MC1R, MLL4, Pkd1, Rhodopsin, and RNF213) at other ...

Trophic relationships of a subtidal fish assemblage in the Francisco Coloane Coastal Marine Protected Area, southern Chilean Patagonia

Polar Research, 2018
A combination of stomach content and nitrogen (δ15N) and carbon (δ13C) stable-isotope analysis was used to assess the trophic interactions and feeding habits of three notothenioid coastal fish (Champsocephalus esox, Patagonotothen tessellata and ...

Pogonophryne neyelovi, a new species of Antarctic short-barbeled plunderfish (Perciformes, Notothenioidei, Artedidraconidae) from the deep Ross Sea

ZooKeys, 2013
This paper continues descriptions of new deep-water Antarctic barbeled plunderfishes of the poorly known and the most speciose notothenioid genus Pogonophryne. It is based on a comprehensive collection obtained by the authors in 2009–2010 during an
