Seismic testing and monitoring of farmed fish- Storfjorden 2009-2010

Open Access Report 2010

Final Report

From June 2009 until June 2010 Petroleum GeoServices (PGS) conducted tests of seismic equipment in a region of Storfjorden, Møre and Romsdal county, Norway. During testing passive and active monitoring of fish were conducted by Møreforsking Marine at the fish farms Skotungneset and Overåneset øst, owned and run by Fjordlaks Akva AS. The aim of the monitoring was a precautionary approach to identify any negative impacts by the tests on fish in the fish farms. Long term effects was planned to be investigated by analyzing the production parameters (fish growth, appetite and mortality) in relation to previous production cycles at the fish farms. Long term environmental monitoring of the fish farms was conducted to identify if any environmental factors could be the reason for a potential discrepancy. Production data from the fish farms were however unavailable at the time of writing, but feedback from Fjordlaks was that the fish farms have not been influenced by the testing activity. To observe more immediate responses fish were monitored with underwater camera at selected days when testing was conducted to try to observe any behavioral changes as a response to the discharges from the air cannon. No such behavioral changes could be observed.
