The skipper of the Faroese fishing boat prevented from landing its mackerel catch in Peterhead has claimed the blockade cost him more than £400,000.
Dozens of local fishermen had taken action when the Jupiter arrived on Tuesday, and it was forced to leave.
It came amid concerns about mackerel quotas for the Faroes.
Jupiter has now returned to its home port, and skipper Emil Pedersen told BBC Scotland its catch would have to go into meal and oil production.
The Faroes has declared a quota of 85,000 tonnes for this year. Previously, Iceland awarded itself 130,000 tonnes.
First Minister Alex Salmond has called for political action to end the ongoing mackerel dispute, which it has been claimed could have serious consequences for the Scottish fleet.
Mackerel is the most valuable stock to the Scottish industry.
