Environmental monitoring and data collection

Environmental monitoring is the first link in the environmental analysis chain – from field data collection to analysis, interpretation, and advice. The Department of Aquatic Resources (SLU Aqua) collects data on fish and shellfish in lakes, rivers, coastal areas and marine waters. Through standardised methods and long-term data series, we generate the knowledge required to understand changes with fish stocks and the environment.

Environmental monitoring along the coast

We monitor fish along the coast to track environmental changes and assess human impact.

Environmental monitoring in lakes

Fish are an important indicator of environmental health – we monitor developments in lakes across the country.

Environmental monitoring in watercourses

We map salmon, trout, and other fish species living in flowing waters – from mountain streams to rivers.

Data collection for DCF

We provide data on fish stocks and catches – to support the EU's Common Fisheries Policy.

A person in a orange raincoat and red gloves lifts a fishing net filled with perch and other fish out of the water. A black plastic tray stands on the boat to collect the catch. In the background, a rocky coastline with trees and bushes.

Effects of thermal discharges

We conduct aquatic ecosystem monitoring outside Sweden’s nuclear power plants and at the Värö Bruk paper mill to assess the effects of thermal discharges.

Our data collection in practice

Here you will find SLU Aqua’s toolbox for data collection – from fish surveys and age analysis to eDNA and sailing drones.
