Environmental guidance for your business in Northern Ireland & Scotland
Waste from fish cages can have a negative impact on the environment. It can:
Your discharge consent or authorisation from your environmental regulator will limit the number of fish held in cages to help minimise the impacts of fish waste.
If you use chemical treatments in cages, you must comply with any limits on chemical use included in your discharge consent or authorisation.
You should use fallow periods, when fish are not held in cages, as they allow the lakebed to recover.
Use tarpaulins to minimise the amount of chemicals applied to the water.
You should take care to ensure that oil or fuel used for boats is not spilt onto land or into watercourses.
When you harvest fish, avoid spilling dead fish or blood into the water. Collect and remove all blood and fish waste. Take care not to spill any ice or water slurry into the water.
Frequently monitor cages for dead fish and remove them from the water as soon as possible
