Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response?

Journal of Fish Diseases, Volume 48, Issue 10, October 2025.
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

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.

Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration

Journal of Fish Biology, Volume 107, Issue 2, Page 480-492, August 2025.
Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...

Development of a Tetrahymena thermophila‐Based Vaccine Expressing Miamiensis avidus Ciliary Proteins to Combat Scuticociliatosis

Journal of Fish Diseases, Volume 48, Issue 6, June 2025.
ABSTRACT Miamiensis avidus is a parasitic pathogen responsible for scuticociliatosis, a lethal infection affecting marine fish worldwide, including Japanese flounder. Immunisation with formalin‐killed M. avidus has shown promise in inducing protective immunity, positioning it as a potential vaccine candidate against scuticociliatosis.
