Copper/Zinc Superoxide Dismutase from the Crocodile Icefish Chionodraco hamatus: Antioxidant Defense at Constant Sub-Zero Temperature

Antioxidants, 2020
In the present study, we describe the purification and molecular characterization of Cu,Zn superoxide dismutase (SOD) from Chionodraco hamatus, an Antarctic teleost widely distributed in many areas of the Ross Sea that plays a pivotal role in the ...

Overwintering Fish Community in Ice‐Covered Environments in Hokkaido, Japan, Inferred From Environmental DNA

Environmental DNA, Volume 7, Issue 2, March/April 2025.
Using fish eDNA metabarcoding, we successfully described an overwintering fish community in ice‐covered environments. eDNA data indicated that the dominant species were Clupea pallasii in the lagoon and Tribolodon spp. in the inlet river. Our findings suggested that the eDNA technique is useful for studying ice‐covered areas and could provide new ...

Abnormal gonads in the Antarctic toothfish (Dissostichus mawsoni Norman, 1937 [Perciformes: Nototheniidae]): the first record and histological description

Polar Research, 2018
This paper describes the morphology and histology of abnormal gonads in Antarctic toothfish (Dissostichus mawsoni) and the possibility of intersexuality and senescence of some individuals. Two old (approximately 25 years) and large (184–185 cm) specimens

An in situ estimate of food consumption by icefish in Lake Chaohu, China

, 2005
The icefish (Neosalanx taihuensis) of Lake Chaohu, China, foraged almost exclusively on crustacean zooplankton in both spring and summer. The icefish showed diurnal feeding periodicity, with peak feeding in the morning.

Dynamic Outlier Slicing Allows Broader Exploration of Adaptive Divergence: A Comparison of Individual Genome and Pool‐Seq Data Linked to Humic Adaptation in Perch

Molecular Ecology, Volume 34, Issue 4, February 2025.
ABSTRACT How genetic variation contributes to adaptation at different environments is a central focus in evolutionary biology. However, most free‐living species still lack a comprehensive understanding of the primary molecular mechanisms of adaptation.

Meta-Transcriptomic Analysis of RNAseq Data Reveals Pacu and Loach Fish with Unusually High Levels of Myoglobin Expression in Skeletal Muscles

Animals, 2020
Oxygen-binding proteins, such as myoglobin, hemoglobin, neuroglobin, and cytoglobin, play a role in oxygen binding and delivery to tissues. In icefish, the loss of myoglobin and hemoglobin genes has been reported to be an adaptive evolution event.

Length–Weight Relationships of 68 Mesopelagic Fish Species From a Subtropical Ocean Basin

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Wet‐weight‐ and dry‐weight‐derived length–weight relationships were estimated for 68 species of mesopelagic fishes found throughout the Gulf of Mexico, 59 of which are new for the region and 28 are new globally. The length–weight relationships obtained were of good fit, with 92% of models having R2 values above 0.90.

Modeling the Water Source Ecosystem in the Middle Route of the South-to-North Water Diversion Project: Implications for Management and Conservation

Fishes
The Danjiangkou Reservoir (DJKR) serves as the water source for the Middle Route of the South-to-North Water Diversion Project (MR-SNWDP), yet comprehensive understanding of its ecosystem structure and function remains limited.
