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.

Infectious Diseases Management in Small‐Scale Freshwater Aquaculture in West Africa: Lessons for Low‐ and Middle‐Income Countries

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Infectious diseases are an increasing threat to food security, small‐scale livelihoods and the sustainability of aquaculture in low‐ and middle‐income countries (LMICs). In sub‐Saharan Africa, aquaculture is expanding rapidly but production systems often remain fragile.

Rapid, sensitive, and visual detection of mandarin fish ranavirus and infectious spleen and kidney necrosis virus using an RPA-CRISPR/Cas12a system

Frontiers in Microbiology
Iridoviruses are large cytoplasmic icosahedral viruses that contain dsDNA. Among them, mandarin fish ranavirus (MRV) and infectious spleen and kidney necrosis virus (ISKNV) are particularly notable due to their high contagiousness and pathogenicity ...

Risk of Spread of Megalocytivirus pagrus1 (Infectious Spleen and Kidney Necrosis Virus) From Frozen Fillets

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT Infectious spleen and kidney necrosis virus (ISKNV) is a significant threat to global aquatic food security by causing large‐scale mortality in the aquaculture of tilapia (Oreochromis niloticus) and mandarin fish (Siniperca chuatsi). ISKNV is a genogroup of Megalocytivirus pagrus1, along with RSIV and TRBIV, and their recent listing as WOAH ...

Natural Co‐Infection With Streptococcus agalactiae and Klebsiella pneumoniae in Cultured Nile Tilapia: Assessing Plant‐Based Therapeutics as Sustainable Alternatives to Antibiotics

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Nile tilapia (Oreochromis niloticus), a key species in global freshwater aquaculture and a major contributor to Bangladesh's fish production, is increasingly affected by bacterial infections that compromise farm productivity. This study investigated natural co‐infection of bacterial pathogens in diseased tilapia and assessed the effectiveness ...

Efficacy of a Combined Natural Extract of Turmeric (Curcuma longa) and Liquorice (Glycyrrhiza uralensis) Against Viral Haemorrhagic Septicaemia Virus in Olive Flounders (Paralichthys olivaceus)

Journal of Fish Diseases, Volume 49, Issue 1, January 2026.
ABSTRACT Viral haemorrhagic septicaemia virus (VHSV) causes a high mortality rate in cultured olive flounder, and effective treatment for VHSV infection is urgently required. Turmeric (Curcuma longa ) and liquorice (Glycyrrhiza uralensis) are well‐known medicinal plants with a variety of biological activities. Turmeric and liquorice extract combination

Geographic Distribution of Epizootic haematopoietic necrosis virus (EHNV) in Freshwater Fish in South Eastern Australia: Lost Opportunity for a Notifiable Pathogen to Expand Its Geographic Range

Viruses, 2019
Epizootic haematopoietic necrosis virus (EHNV) was originally detected in Victoria, Australia in 1984. It spread rapidly over two decades with epidemic mortality events in wild redfin perch (Perca fluviatilis) and mild disease in farmed rainbow trout ...

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
