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

open access: yesJournal 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

open access: yesJournal 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.

The Current State of Knowledge of the Economic Impact of Diseases in Global Aquaculture

open access: yesReviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Aquaculture has been rapidly growing over the past few decades and has become an important contributor to global food security. As production increases, the intensification of production increases the risk of disease outbreaks. Infections caused by viral, bacterial, and parasitic pathogens represent a major threat to farm economy and growth ...

Application of Conservation Genomics to Investigate the Role of Pathogens on the Migration of Sea‐Run Brown Trout (Salmo trutta)

open access: yesJournal of Fish Diseases, Volume 48, Issue 5, May 2025.
ABSTRACT Pathogens play a key role in individual function and the dynamics of wild populations, but the link between pathogens and individual performance has rarely been investigated in the wild. Migrating salmonids offer an ideal study system to investigate how infection with pathogens affects performance given that climate change and fish farming ...
