Exploring Silver as an Alternative Treatment for Controlling Macrogyrodactylus congolensis Populations

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Monogeneans are ectoparasites that in high densities, can cause harm and even death to their hosts. Therefore, treatment methods are continuously evaluated. The current study aims to determine the LC50 of ionic silver and silver‐engineered nanomaterials (ENMs) (nAg) in the monogenean Macrogyrodactylus congolensis and report on the toxicological effects

Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...
