Microbiome and Pathobiome Characterization in Farmed Barramundi (Lates calcarifer) During and Post Scale Drop Disease Outbreaks

Journal of Fish Diseases, EarlyView.
ABSTRACT Large‐scale double‐digest RAD sequencing (ddRADseq) datasets generated for genotyping are increasingly available in aquaculture, yet their unmapped reads remain largely unexplored for pathogen surveillance. Here, we evaluated the utility and limitations of repurposing unmapped ddRADseq reads to examine pathogen‐associated and disease ...

Lymphocystis Disease in Endemic Aotearoa New Zealand Bully (Gobiomorphus cotidianus)

Journal of Fish Diseases, EarlyView.
ABSTRACT We detected lymphocystis disease virus (LCDV) for the first time in an Aotearoa New Zealand freshwater environment, from an individual common bully, toitoi, Gobiomorphus cotidianus (Eleotridae). Dinah's bully, Gobiomorphus dinae, and Kaharore bully, Gobiomorphus mataraerore, also exhibited gross nodular lesions on the fins but were not sampled.

Application of Environmental DNA for Monitoring Red Sea Bream Iridovirus at a Fish Farm

Microbiology Spectrum, 2021
Red sea bream iridoviral disease (RSIVD) causes high economic damage in mariculture in Asian countries. However, there is little information on the source of infection and viral dynamics in fish farms. In the present study, the dynamics of RSIV in a fish

A Formalin‐Inactivated Vaccine Enhances Survival and Mitigates Horizontal Transmission of Red Sea Bream Iridovirus (RSIV) in Rock Bream (Oplegnathus fasciatus): Insights From Viability Quantitative PCR

Journal of Fish Diseases, Volume 49, Issue 9, September 2026.
ABSTRACT Formalin‐inactivated vaccines are widely employed as a primary preventive strategy against red sea bream iridoviral disease (RSIVD), which poses a substantial economic threat to the aquaculture of rock bream (Oplegnathus fasciatus). However, conventional quantitative PCR (qPCR) cannot differentiate infectious virions from noninfectious vaccine

Prevalence of Infectious Spleen and Kidney Necrosis Virus (ISKNV), Nervous Necrosis Virus (NNV) and Ectoparasites in Juvenile Epinephelus spp. Farmed in Aceh, Indonesia

Pathogens, 2020
A cross-sectional survey was used to estimate the prevalence of infections with the Infectious spleen and kidney necrosis virus (ISKNV, Megalocytivirus), nervous necrosis virus (NNV, Betanodavirus), and infestations with ectoparasites during the rainy ...

Outbreak investigation attributes Infectious spleen and kidney necrosis virus as a necessary cause of a mortality epidemic in farmed grouper (Epinephelus spp.) in Bali, Indonesia

Aquaculture Reports, 2021
In 2016, famers reported mass mortality events in hybrid grouper within 2–4 weeks following transfer to sea cages on the northern coast of Bali. The objective was to obtain an aetiological diagnosis using a broad range of traditional and emerging ...

The First Report of a Megalocytivirus Infection in Farmed Starry Flounder, Platichthys stellatus, in Korea [PDF]

Fisheries and aquatic sciences, 2013
In 2009, a systemic megalocytivirus infection associated with high mortality was detected for the first time in cultured starry floun der Platichthys stellatus in Korea. Diseased starry flounder had pale bodies and gill coloring and enlarged spleens. Histopathologi cal examinations revealed basophilic enlarged cells in various organs of diseased starry

Viral Pathogens Threatening Cage‐Cultured Nile Tilapia in Lake Victoria: Epidemiology, Emerging Risks and Integrated Health Management Strategies

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The rapid expansion of cage culture for Nile tilapia (Oreochromis niloticus) in Lake Victoria is central to food security and profitable development in East Africa. Nevertheless, viral conditions affect the sustainability of this sector, with significant imbalances in livelihood, trade and aquaculture adaptability.

Poly(I:C) induces antiviral immune responses in Japanese flounder (Paralichthys olivaceus) that require TLR3 and MDA5 and is negatively regulated by Myd88. [PDF]

PLoS ONE, 2014
Polyinosinic:polycytidylic acid (poly(I:C)) is a ligand of toll-like receptor (TLR) 3 that has been used as an immunostimulant in humans and mice against viral diseases based on its ability to enhance innate and adapt immunity. Antiviral effect of poly(I:

Quantitative analysis of the clinical signs in marine fish induced by Megalocytivirus infection

Journal of fish pathology, 2011
In quantitative studies of clinical signs, rock bream of adults and juveniles infected with Megalocytivirus IVS-1 isolated from rock bream (Oplegnathus fasciatus) in Korea showed average and of spleen index respectively. In challenge experiments, Megalocytivirus IVS-1 induced 100% cumulative mortality in both adult and juvenile rock bream.
