Therapeutic Efficacy of Monoterpenes in Nile Tilapia Infected With Edwardsiella tarda: A Phytogenic Alternative to Oxytetracycline

Journal of Fish Diseases, EarlyView.
ABSTRACT The purpose of this research was to assess the effectiveness of a combination of monoterpenes (thymol and carvacrol) in treating juvenile Nile tilapia (Oreochromis niloticus) infected with Edwardsiella tarda as a potential substitute for the antibiotic oxytetracycline. The study utilised different concentrations of the monoterpenes blend (MTs):

Crosstalk between thyroid hormones and the central corticotropin‐releasing factor system in Atlantic salmon

Journal of Neuroendocrinology, EarlyView.
The corticotropin‐releasing factor (CRF) system plays a key role in centrally regulating thyroid hormone (TH) synthesis in non‐mammalian vertebrates, but interactions between THs and the CRF system remain poorly understood in fish. Here, we report that THs directly affect transcription of several CRF system components across different hypophysiotropic ...

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

Molecular Ecology, EarlyView.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Pyriproxyfen Disrupts the Ongoing Spermatogenesis Wave in Danio rerio Potentially Mediated by Voltage‐Dependent Calcium Channels and Protein Kinase C

Journal of Applied Toxicology, Volume 45, Issue 9, Page 1705-1719, September 2025.
ABSTRACT Pyriproxyfen (PPX) is an analog of the juvenile hormone from insects. Following our previous studies, for the ex vivo short‐term effect, we chose 10−9 M pyriproxyfen to analyze the morphology of spermatogenesis wave cells. In silico docking and ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) studies were carried out to ...

Severe Outbreak of Saprolegnia Spp. Infection in Spotted Snakehead (Channa punctata, Bloch 1793): Clinical Assessment, Histopathology, Haemato‐Biochemical Indices and Insights Into Therapeutic Effects

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Spotted snakehead (Channa punctata) naturally infected with Saprolegnia spp. were confirmed by clinical signs, wet mount examination and histopathology. In the therapeutic trial using various chemotherapeutics, elevated temperature combined with 2% NaCl (T4) resulted in the highest survival rate (70%). ABSTRACT Saprolegniasis, caused by Saprolegnia spp.
