Start year 2021 End year 2024 Funding (€) € 1,110,092 Website https://www.fhf.no/prosjekter/prosjektbasen/901674/ Summary The project is a comprehensive ""effort"" where researchers and the aquaculture industry work closely together to increase knowledge about the prevalence and importance of ILAV HPR0 in Norwegian hatcheries. Introduction and maintenance of contagion/infection, including how the virus spreads in the facilities, will be mapped and virus-independent factors that can contribute to disease development will be identified. Development of the ILA virus and the salmon's responses will be followed over time, and a number of samples will be taken from various stages for use in laboratory studies for the identification of biological drivers. Systematic monitoring of the facilities will ensure material for genetic studies of virus variation within a population infected with ILAV HPR0, transitional phases towards ILAV HPRΔ and variation within ILA outbreaks.
The project also includes the development of methods for targeted and cost-effective detection of ILAV HPR0 and changes to more disease-causing variants.
Main objective:
To increase knowledge about the transition from non-virulent to virulent ILA virus (ILAV) and to prepare best-practice biosecurity measures for hatcheries that can reduce the risk of change to, and spread of, virulent ILAV.
Sub-goals:
• Map the prevalence and spread of non-virulent ILAV HPR0 in the hatchery phase.
• Estimate the effect of remediation for ILAV HPR0 in hatcheries.
• Map the connection between the detection of ILAV HPR0 in hatchery fish and the occurrence of ILA disease in the sea.
• Identify risk factors/drivers for the development of disease-causing ILAV.
• Establish test regimes for targeted detection of both non-virulent and virulent ILAV.
• Develop best-practice biosecurity measures based on existing and new knowledge to limit spread and reduce the risk of a change from ILAV HPR0 to ILAV HPRΔ.
• Characterize the dynamics and especially the order of the genomic changes from HPR0 to HPRΔ.
• Elucidate whether impaired gill health or gill inflammation can be a driver for changing HPR0 to HPRΔ.
