Information regarding aquaculture and its importance to Scotland's economy.
Aquaculture is defined as the rearing of aquatic animals or the cultivation of aquatic plants in both seawater and freshwater for food and can take many forms.
In Scotland, aquaculture is dominated by the production of fish – predominantly salmon, trout, cod and halibut, and shellfish such as mussels, oysters and scallops – but there are other important sectors as well.
Aquaculture contributes to

Radioactive substance notifications
You need to notify SEPA if you:
manage any of the following radioactive sources:
sealed sources in IAEA category 5 that exceed 200 kBq;
tritium sources that exceed 20 GBq;
electrodeposited sources
manage a radioactive orphan source
manage radioactive waste from an incident (MS Word, 238 kB)
You don't need to notify SEPA if the activity can be carried out under a permit or registration that yo
Alloa monitoring buoy, Firth of Forth
Continuous monitoring equipment has been deployed from a buoy in the upper Forth estuary near South Alloa since 1988 to monitor dissolved oxygen, salinity, temperature and turbidity. Dissolved oxygen is consumed by the decomposition of organic matter. Organic matter in the upper Forth estuary originates from discharges of organic waste and organic rich sediments mixed into the water column as a re
Dunoon continuous water quality monitoring buoy, Firth of Clyde
Since 2009 a monitoring buoy has been deployed in the Firth of Clyde adjacent to Dunoon. This location is a long term monitoring site for both marine chemical and ecological parameters and was previously monitored on a monthly basis. Continuous monitoring equipment attached to the buoy detects short term changes in water quality that are missed by monthly monitoring.

Gunnet Ledge monitoring buoy, Firth of Forth
Continuous salinity, temperature, and chlorophyll data has been collected from in the Inner Firth of Forth at Gunnet Ledge since 1993. Chlorophyll-a is used to indicate the biomass of phytoplankton. Phytoplankton growth is stimulated by nutrients exported from the estuary into the clearer coastal waters of the Firth of Forth. Excessive phytoplankton growth may cause an undesirable disturbance to t
Inner Clyde Estuary monitoring buoy, Firth of Clyde
Continuous water quality monitoring equipment was deployed in the inner Clyde estuary adjacent to Govan in 2011. Low dissolved oxygen concentrations are known to occur in the inner Clyde estuary at this location as a result of the decomposition of organic wastes from discharges and urban run off.
Limited mixing between fresh water and more dense saltwater leads to large differences between the sal
National Marine Monitoring buoy network
The SEPA Marine National Environmental Monitoring Buoy Network provides real time, high frequency environmental data from strategic locations around the coast, as part of SEPA obligations to monitoring the marine environment.
What is being monitored?
Continuous monitoring equipment gathers dissolved oxygen, water temperature, salinity and chlorophyll-a data at regular intervals. The data is stored

Flood maps
Our flood maps are designed to help you understand how you could be affected by flooding. The maps show you areas which are likely to flood from rivers, the sea and surface water.
The flood maps are a public tool and used by a wide variety of people for a range of work.
We currently have two map viewers available. To determine which viewer will benefi
