Frequently asked questions
Why is a sea lice framework needed?
Populations of wild Atlantic salmon have been in serious decline in recent decades and are now at crisis point. The pattern of decline is repeated across the salmon’s North Atlantic range and is likely caused, at least in part, by the effect of climate change on the survival of salmon during their time at sea.
To build resilience of Sc

Nitrates monitoring
Our groundwater monitoring networks ensure that Scotland’s groundwater supplies are adequately protected.
SEPA’s nitrate monitoring network aims to identify areas affected by nitrate pollution, or at risk of being affected, and to find out if any improvement actions taken to address nitrate problems are effective.
To achieve these aims, SEPA currently monitors 270 groundwater sites across Scotland
