Biological recipient monitoring at the Barsebäck nuclear power plant – fish, bottom macro fauna, birds and temperature

Last changed: 02 November 2016

Potential ecosystem effects caused by the effluent cooling water from the Barsebäck nuclear power plant are monitored in yearly surveys by Institute of Coastal Research, Department of Aquatic Recourses (SLU Aqua). The emphasis is on studies of fish populations.

The first reactor at Barsebäck nuclear power plant was commissioned in 1975, the second one in 1977. The first nuclear reactor was running until 1999 and the second one until 2005.

A fyke net survey has been carried out during three weeks in April and three weeks in August until 2009, in a program established by County administrative board. After that the fyke net survey has continued in a different arrangement. The survey is done in a gradient from the area that is most affected by the cooling water to the unaffected reference areas.

Staff from Institute of Coastal Research at SLU Aqua also collects biological material from both land and sea for a radio ecology monitoring program under the responsibility of the Swedish Radiation Safety Authority (SSM).

The results from the biological recipient monitoring was summarized in 2008 .

The continued fyke net surveys are reported annually .

The results from the biological recipient monitoring are reported annually. Se reports below.
The surveys generate fishery independent data regarding cod and eel in Öresund that are of value for fisheries management. We have data series that started in the 1970s, which are unique. Eel data from Barsebäck are annually reported to EIFAC/ICES Working Group on Eels, as a basis of international fisheries management.
