According to manager of the marine resources division at the Icelandic Marine Research Institute (Hafró), Þorsteinn Sigurðsson, there are likely more than 200,000 tons of living herring in the fjord.

Specialists from Hafró are currently in Kolgrafafjörður considering other alternatives, visir.is reports.

An estimated 52,000 tons of herring died in the fjord. Work on burying the dead herring with the use of heavy machinery continues. It is expected that up to 15,000 tons of herring have been buried in the area so far, while approximately 1,000 tons of grútur, herring fat, has been removed to be disposed of at a different location.

The fish are believed to have died due to lack of oxygen in the fjord caused by a landfill and bridge constructed across the fjord in December 2004.
