Advances in aquatic animal health within the framework of the World Organisation for Animal Health.

The World Organisation for Animal Health (WOAH) seeks to improve animal health by promoting safe trade in animals and their products, setting standards for diagnostic methods, detection of emerging diseases and confirmation of listed diseases in clinically affected animals and surveillance in healthy populations. WOAH launched the Aquatic Animal Health Strategy (AAHS) in 2021 in recognition of the growing importance of aquatic animal products in global food security. Disease is currently a major limiting factor in the sustainable growth and development of the aquaculture industry, impacting the industry's ability to increase yields to meet future food demands.

Cell death induced by Lepeophtheirus salmonis labial gland protein 3 in salmonid fish leukocytes: A mechanism for disabling host immune responses.

The salmon louse (Lepeophtheirus salmonis) is an ectoparasite feeding on mucus, skin, and blood of salmonids. On parasitised fish erosions and, at later lice stages, ulcerations appear at the louse feeding site. In susceptible species like Atlantic salmon (Salmo salar) with a limited rejection of lice, only a mild inflammatory response with minor influx of immune cells is seen at these lesions, as the salmon louse secrete proteins that can dampen immune responses.

Laboratory Replication of Ostreid Herpes Virus (OsHV-1) Using Pacific Oyster Tissue Explants.

Pacific oysters ( or ) are one of the most economically important aquaculture species globally. Over the past two decades, ostreid herpesvirus (OsHV-1) has become a major pathogen of cultured Pacific oysters, resulting in widespread mortality with a global distribution. Experimental use of OsHV-1 is challenging for many reasons, including both complexity of host-pathogen dynamics and a lack of functioning model systems.

In field use of water samples for genomic surveillance of infectious spleen and kidney necrosis virus (ISKNV) infecting tilapia fish in Lake Volta, Ghana.

Viral outbreaks are a constant threat to aquaculture, limiting production for better global food security. A lack of diagnostic testing and monitoring in resource-limited areas hinders the capacity to respond rapidly to disease outbreaks and to prevent viral pathogens becoming endemic in fisheries productive waters. Recent developments in diagnostic testing for emerging viruses, however, offers a solution for rapid monitoring of viral outbreaks.
