SLU and SMHI perform a number of missions and surveys each year, on assignment from the Swedish Agency for Marine and Water Management (SwAM), as part of the national environmental monitoring of the water surrounding Sweden.
SLU’s Department of Aquatic Resources (SLU Aqua)
Each year SLU Aqua performs five internationally coordinated fish surveys with trawls and advanced sonar, in the Baltic, Kattegat, and Skagerrak. The purpose is to collect fishery independent estimates of the amount of fish in different areas, as well as the amount of juvenile fish. The surveys collect information about different species, which is subsequently used for fish stock estimates and advice on how much can be fished in a sustainable way.

Swedish Meteorological and Hydrological Institute (SMHI)
SMHI’s oceanographic research group performs a large part of the national environmental monitoring in the pelagic water mass around Sweden. The monitoring main focuses mainly on eutrophication, the extent of oxygen-free bottoms, marine acidification, physical oceanography, hydrography for fisheries, marine biology, climate change, and data assimilation for oceanographic models.

Swedish Agency for Marine and Water Management (SwAM)
Swedish Agency for Marine and Water Management (SwAM) was created 2011 when parts of Swedish National Board of Fisheries were joined with the functions from the Swedish Environmental Protection Agency that worked with water issues. The agency has the overall responsibility for seas, lakes, and water courses, and it finances a large part of the national and regional monitoring of the environmental status and fish stocks that is done in Sweden. All monitoring is commissioned by SwAM but it is performed by other authorities and private enterprises, e.g. SMHI and SLU Aqua. Monitoring of the open sea, both regarding environment and fish, is dependent on the availability of a large enough research vessel that the surveys can be performed year-round and in basically any weather.
