Shipping and the Spread of Infectious Salmon Anemia in Scottish Aquaculture
Figure 3. Infection status of areas versus number of well-boat visits. Infection status is 0 for no infection, 1 for suspected infection, and 2 for confirmed infection. Skye and Shetland, infected by fish transferred from Loch Nevis, are shown as large hollow squares, while the unconfirmed infection at Loch Broom is shown as a large triangle-filled square. Loch Creran is shown as a cross and is excluded to prevent double counting of harvest transport voyages. Regression is 0.012 x visits, r2 = 0.66, p = 0.000004.
