摘要

Infectious pancreatic necrosis virus (IPNV) is a very widespread pathogen in the Scottish salmon farming industry. Because it was notifiable and subject of official controls, an extensive data set is available on the prevalence of IPNV. Combined witha well documented industry, these data have allowed the construction and testing of a model of the spread of IPNV between farm populations. This model uses a standard Susceptible -Infected (SI) epidemiological model to describe the spread of infection.This model is implemented in both freshwater and marine phases, with marine farms being supplied with smolts from one or more freshwater sites. There is no loss of infection from a population until it is harvested. The model indicates major reductions are required in transmission in both the freshwater and marine environments if IPNV is to be eradicated. Obtaining smolts from more than one source also increases marine infection pressure substantially. Even extensive improvements in marine biosecurity are ineffective on their own - while forming a vital part of a co-ordinated eradication strategy.
