Netting the Stress Responses in Fish

Frontiers in Endocrinology, 2019
In the last decade, the concept of animal stress has been stressed thin to accommodate the effects of short-term changes in cell and tissue physiology, major behavioral syndromes in individuals and ecological disturbances in populations.

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Evolutionary Dynamics and Functional Conservation of amh Signaling in Teleost Lineages

Fishes
The anti-Müllerian hormone (amh) and its receptor, amhr2, along with the downstream bone morphogenetic protein receptors (bmprs), have been recognized as the central regulators in teleost sex determination (SD) and differentiation.

Role of aquaporins during teleost gametogenesis and early embryogenesis

Frontiers in Physiology, 2011
Aquaporins are believed to be involved in homeosmotic mechanisms of marine teleosts. Increasing data suggest that these molecular water channels play critical roles associated with the adaptation of gametes and early embryos to the external spawning ...

Pathophysiological Mechanisms of Emaciation Syndrome in Plectropomus leopardus: Insights From Histology and Transcriptomics

Animal Research and One Health, EarlyView.
Integrated phenotypic, histological, transcriptomic, and validation analyses reveal that emaciation syndrome in Plectropomus leopardus is associated with intestinal structural damage, hepatic metabolic remodeling, and muscle protein degradation, highlighting coordinated multi‐tissue alterations underlying disease progression.

The battle between bacterial infection and autophagy in aquatic animals

Frontiers in Immunology
Autophagy is a conserved cellular degradative pathway that has been demonstrated to play a crucial role in the innate immune response to combat infection with a range of pathogenic bacteria via xenophagy.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Impact of Amirthalingamia macracantha Larvae on Nile Tilapia (Oreochromis niloticus): A Morpho-Histopathological Perspective

Animals
Amirthalingamia macracantha (Joyeux and Baer, 1935) larvae, a member of the Gryporhynchidae family (Cestoda: Cyclophyllidea), are commonly found in a variety of African fish species, including Nile tilapia (Oreochromis niloticus, Linnaeus, 1758 ...
