Monitoring
In order to maintain farm sites, and the water bodies containing them, in a sustainable condition, it is necessary to ensure that certain indicators remain within the limits set by Ecological Quality Objectives. These indicators are listed below. We include suggestions for monitoring frequencies when operational monitoring (as defined by the WFD) is required.
| Environment/farm type/species | Indicator Category | Scale | Recommended Indicators | Relevant models |
| Fjords, sea-lochs and voes: salmon, trout and cod in floating cages | Benthic Impact | A:farm | ITI, AMBI, etc .... | DEPOMOD |
| Fjords, sea-lochs and voes: salmon, trout and cod in floating cages | Pelagic Impact | B: water body | Winter DIN and/or DIP Minimum DO Maximum chlorophyll Transparency | FjordEnv LESV |
| Atlantic coastal waters: bivalve molluscs in seabed, long-line and table cultures | Pelagic Impact | B: water body | DO reduction compared with reference Chlorophyll reduction compared with reference | ?? |
| Mediterranean open coastal waters; Sea-bass, sea-bream, tuna in floating cages | Benthic Impact | A:Farm scale | AMBI etc | MERAMOD TRIMODENA |
| Mediterranean open coastal waters; Sea-bass, sea-bream, tuna in floating cages | Pelagic Impact | B:Water Body | DIP Transparency | ?? |
We have assumed that farmers will monitor pelagic conditions within cages, in the interests of fish health; however, you, or animal health organizations, may wish to audit this monitoring. In some States, farmers are required to carry out benthic monitoring as a condition of their licence, using approved consultants.
