Book excerpt: Infectious salmon anemia (ISA) was first detected in salmon farms in southwestern New Brunswick in 1996. In an effort to help estimate the potential for water-borne exchange of the ISA virus among farms in this area, we used a three-dimensional tidal water circulation and particle transport model. Water exchange scenarios based on the movement of particles during one tidal excursion, as predicted by the model, are compared to those estimated by a simple method assuming a 5-km radius circular zone of water exchange around each farm. In this report, we examined the water exchange among farms in the Passamaquoddy Bay area, as well as with farms in adjacent areas. We also examined the relative risks, with respect to the water-borne spread of disease, of two potential locations for a proposed new salmon farm in northern Passamaquoddy Bay
