Simulated Infectious Salmon Anemia Virus Dispersion in Quoddy Region

Synthetic data from a modeling framework simulates the waterborne dispersal of infectious salmon anemia virus from Atlantic salmon farms. The simulation incorporates ocean circulation, particle tracking, dynamic infection, and virus inactivation models. It was produced by researchers from Fisheries and Oceans Canada and published in FACETS in 2024.

Use Cases

• Analyze spatiotemporal variation in simulated ISAV concentration in relation to current speed and direction.
• Model connectivity and asymmetrical transmission pathways between aquaculture sites based on seaway distances.
• Conduct sensitivity analyses on viral dispersal outcomes using parameters from the viral decay and inactivation models.
• Simulate pathogen exposure risks for wild and farmed species by tracking advected particle cohorts from hypothetically infected farms.

Strengths

• Model integrates multiple simulation components: ocean circulation, particle tracking, infection dynamics, and virus inactivation.
• Framework is designed for a specific, ecologically significant pathogen (Infectious Salmon Anemia Virus) in a defined geographic region.
• Study includes sensitivity analysis to quantify the impact of uncertainty in key parameters like viral decay rates.

Limitations

• Dataset consists of synthetic simulation outputs, not directly observed empirical measurements.
• The underlying viral decay and inactivation rates, which significantly impact results, have associated uncertainty as noted in the study.
• Specific quantitative details like simulation row count, temporal resolution, or grid size are not provided in the available metadata.
