Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Genome‐Wide Protein Interaction Analysis in Parasitic Gyrodactylus Flatworms–Fish Hosts System and Drug Target Identification

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Genomic data offer a powerful tool for studying the molecular interactions between parasites and their hosts, but they remain scarce for parasitic monogenean flatworms. This study presents the first high‐quality phased genome assembly for monogeneans (Gyrodactylus kobayashii), and uses it to predict key interacting proteins between monogenean parasite ‐

Hexabothriid monogeneans from the gills of deep-sea sharks off Algeria, with the description of Squalonchocotyle euzeti n. sp. (Hexabothriidae) from the kitefin shark Dalatias licha (Euselachii, Dalatiidae)

Helminthologia, 2016
Sharks (765 specimens from ten species) from the Mediterranean Sea off Algiers, Algeria, were examined for the presence of gill monogeneans. The following deep-sea sharks were investigated from 2009 to 2015: Centrophorus granulosus (27 specimens ...

The Role of the Middle East in the Biogeographical Dispersal of Host‐Specific Parasites: Monogeneans and Their Cyprinoid Fish Hosts

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study investigates the diversity and phylogeny of Dactylogyrus species in the Middle East, as well as uncovers the historical dispersal routes and biogeographical contacts of cyprinoid host species using their host‐specific parasites. Location The Middle East. Taxon Dactylogyrus (Dactylogyridae: Monogenea), Cyprinoidei (Cypriniformes).

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...
