Quantitative Analysis of Individual‐ and Group‐Level Viral Shedding Reveals Transmission Dynamics of Viral Hemorrhagic Septicemia Virus (VHSV) in Olive Flounder (Paralichthys olivaceus)

Journal of Fish Diseases, EarlyView.
ABSTRACT Viral hemorrhagic septicemia virus (VHSV) is a highly pathogenic rhabdovirus that primarily spreads through horizontal transmission. Characterizing viral shedding dynamics is therefore critical for understanding its epidemiology and improving disease control strategies in aquaculture.

Phenotypic Florfenicol Resistance in floR‐Harbouring Flavobacterium psychrophilum Isolates (CC‐ST90): A Case Study From Danish Freshwater Rainbow Trout Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Monitoring antimicrobial resistance (AMR) in fish pathogens is essential for supporting sustainable aquaculture. In this study, susceptibility testing and genome sequencing were used to characterize the AMR profile of seven Flavobacterium psychrophilum originating from Danish rainbow trout farms (2019–2022).

Retrospective Identification of Lactococcus petauri Among Archived Isolates From Farmed Fish in Japan: Pathogenicity and Molecular Epidemiology

Journal of Fish Diseases, EarlyView.
ABSTRACT Lactococcosis, caused by Lactococcus garvieae, L. formosensis, and L. petauri, is an important bacterial disease of farmed fish worldwide. In Japan, L. petauri has not previously been reported as a cause of lactococcosis, although lactococcosis cases not attributable to either L. garvieae or L. formosensis have been recorded.

Immunogenicity and Protective Efficacy of the First Autogenous Aeromonas hydrophila Vaccine for Piaractus brachypomus

Journal of Fish Diseases, EarlyView.
ABSTRACT Aeromonas hydrophila is a major zoonotic bacterial pathogen responsible for haemorrhagic septicemia, substantial economic losses in aquaculture and increasing antimicrobial resistance among field isolates. It is also one of the main bacterial species associated with mortality outbreaks in pirapitinga, Piaractus brachypomus, culture in the ...

Suitable Substrates for Black Soldier Fly Larvae Production: A Pathway Towards Sustainable Aquafeed Production

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Due to the rapid growth in aquaculture, there is an urgent need to explore alternative sustainable sources for fish feed other than conventional fishmeal. Black soldier fly larvae (BSFL) have been identified as a potential source of protein that could transform waste materials into high‐value biomass. This review critically synthesizes current

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio)

Environmental Toxicology, Volume 41, Issue 10, Page 1027-1040, October 2026.
ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...

Scale Dependent Temporal and Spatial Patterns of Population Change in Anadromous Sea Trout (Salmo trutta) in Scotland Over Seven Decades

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT The spatial scale at which temporal change in a population is measured has the potential to skew the inferences drawn on patterns of change from monitoring data. This study analysed data from rod catches of anadromous sea trout (Salmo trutta) in Scotland over 72 years and three spatial scales (National, Regional and District).

Monte Carlo Simulation of Pesticide Toxicity for Rainbow Trout (Oncorhynchus mykiss) Using New Criteria of Predictive Potential

Journal of Xenobiotics
Background: The toxicity of pesticides for fish in general and Rainbow Trout (Oncorhynchus mykiss) in particular is an important ecological indicator required by regulations, and it implies the use of a large number of fish.

Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

Fisheries Management and Ecology, Volume 33, Issue 5, Page 879-893, October 2026.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...
