Exposure | Average harvested biomass (tons, 2017–2018) per ACS representing the potential loss magnitude per ACS | ≤5000 | 5001–10000 | 10,001–15000 | 15,001–20,000 | >20,000 |
Sensitivity factors | i Accumulated biomass (2010–2018) per unit area (tons/ha) per ACS, representing accumulated stress to the concession area (potential eutrophication, diseases etc.) | ≤300 | 301–600 | 601–900 | 901–1200 | >1200 |
ii Atlantic salmon dominance (% of total harvest per ACS). | ≤20 | 20.1–40 | 40.1–60 | 60,1–80 | >80 | |
iii Health management condition as average (2017–2018) total antibiotic (AB) use (tons) per ACS | ≤4 | 4.1–8 | 8.1–12 | 12.1–16 | >16 | |
iv Unfavourable environmental conditions represented by number of algal bloom (HAB) events causing fish mortality within each ACS (2000–2016) | <2 | 2–5 | 6–10 | 11–20 | >20 | |
v-Distance to nearest port (km) and access facility (land and sea) | ≤30 Access by land and sea | <30 and ≤50 Access by land and sea | >50 and ≤100 Access by land and sea | >50 and ≤100, Access only by sea | >100, Access only by sea | |
Hazard | Access reduction due to sanitary barriers and movement of personnel and/or harvesting reduction due to limited capacity in processing plants required to respect social distancing | <20% | 20–39% | 40–59% | 60–80% | >80% |
