Environmental guidance for your business in Northern Ireland & Scotland

Non native species at fish farms

Non-native species at fish farms

What you must do

In Scotland you must obtain a permit to introduce non-native species into aquaculture. You must also obtain a permit to move locally absent species (native) within Scotland, or to Scotland from elsewhere in the UK.

In Northern Ireland, you must hold a licence from the Northern Ireland Environment Agency if you release or allow the escape into the wild of any fish or shellfish that are not native to Northern Ireland.

Under general licence, you may release pacific oysters into the wild, including growing them in the open on the seabed.

If you farm manila clams that are kept under netting you do not need a licence, as this does not constitute a release into the wild.

  • A day with Hydrology, SEPA's hydrometry unit is responsible for around 400 gauging stations and 350 rainfall monitoring sites. River gauging stations are important as they allow river levels to be monitored so flood events can be predicted and flood warnings sent out.

  • Brewing and Distilling Technical Drop-in Day: Waste, Water, Energy, Brewing and Distilling is booming due to high demand for quality Scottish beers and spirits. All this growth is also leading to a boom in food waste, energy and water use.
