Viruses

Researchers from the University of Sydney and the University of Florida have developed a single test that can identify all three variants of the deadly ISKN virus, helping strengthen Southeast Asia’s barramundi sector.

A new laboratory study shows that microplastics can negatively impact fish health and physiology, finding that the presence of plastic fragments can make IHNV outbreaks more damaging.

Researchers are putting additional resources into encapsulation methods and fortifying live feed for oral fish vaccines as the market expands, hoping that these steps could improve vaccine effectiveness and further safeg…

Asia’s shrimp farmers need to reboot their attitude to biosecurity and stocking densities, argues Robins McIntosh, in a follow-on to Monday’s article on the dangers of disinfection*.

A consortium of researchers have reviewed and outlined the emerging and increasing disease threat facing Macrobrachium rosenbergii aquaculture and notes the sector's current reliance on antibiotic therapies.

The early identification of white spot syndrome virus (WSSV) in shrimp could be achieved with the naked eye, by utilising the light scattering properties of gold nanoparticles (GNPs).

A new paper argues that there’s an urgent need to improve understanding of the genetic mechanisms involved in host resistance to whitespot syndrome virus (WSSV) and sea lice – two of the greatest health challenges facing…

A traditional Chinese herbal prophylactic, containing bioavailable phytonutrients recovered from the Camellia sinensis tea bush, has been shown to protect shrimp from outbreaks of AHPND and WSSV.

Although Tunisia has a relatively undeveloped aquaculture sector, it has huge potential – with 1,350 kilometres of Mediterranean coastline, a maritime domain of over 80,000 square kilometres and seven lagoons covering 10…

The Bureau of Fisheries and Aquatic Resources (BFAR) in the Philippines has approved GenoMar for the world's first specific pathogen-free (SPF) certification for tilapia.

Dr Melony Sellars, CEO and managing director of Genics Pty Ltd, recently developed four new real-time PCR assays that can help detect the presence of decapod iridescent virus (DIV1) in shrimp.

TransAlgae is currently looking to raise $12 million to complete development of an algae-based oral treatment against whitespot syndrome virus (WSSV) in shrimp.

Researchers are beginning to highlight the potential of immunostimulants as a sustainable disease prevention strategy for shrimp aquaculture. Here’s a run-down of how these molecules work, their origins and how they can …

A team of researchers have found that vaccinating tilapia broodstock may confer partial protection from tilapia lake virus (TiLV) to their eggs and larvae.

The EU-funded VIVALDI project has released its full technical manual on bivalve biosecurity and disease management, along with recommendations to prevent, mitigate and control diseases in shellfish.

Over 4,000 live carp from Hungarian fish farms were seized in a raid in Dover last month by the UK's Fish Health Inspectorate (FHI).

Researchers in China caution that some commercial probiotics for the aquaculture industry may be mislabelled, and also contain cytotoxins and antibiotic resistance genes that can be passed to other organisms.

Farmers in West Africa are increasingly looking to the use of plants and algae to help improve the health of their fish.

Despite being susceptible to multiple viral and bacterial diseases, less than 5 percent of farmed tilapia are vaccinated. How can stakeholders work together to improve the industry’s vaccine uptake?

A gene affecting resistance to a viral disease in Atlantic salmon has been identified using CRISPR gene-editing technology.
