Nine positive Covid-19 cases are now linked to the fishing vessel cluster in Orkney.
The figure has risen by three from Friday, with the new cases all crew members from the Orkney-registered boat Aalskere. All have been self-isolating.
NHS Orkney director of public health Louise Wilson said contact tracing in Orkney was now complete and all those at risk had been spoken to.
She said: “While the immediate challenge has passed, Aberdeen remains in lockdown and we cannot be complacent.

“We urge the community to take care and to follow the FACTS guidance to limit the spread of the virus.”
NHS Grampian and NHS Highland have also been contact tracing due to the boat visiting Peterhead in Aberdeenshire and Scrabster in the Highlands.
The crewman who tested positive had visited Aberdeen while the trawler was in Peterhead.
This visit, and the boat’s fishing trip, happened in the weeks before a cluster was confirmed in Aberdeen, and lockdown restrictions were re-imposed.
NHS Highland said it was “confident” the members of the crew took precautions when they visited Scrabster.

The Scottish Fishermen’s Federation said Scotland’s whitefish fleet had continued to work through the coronavirus pandemic as a “key part of the food supply chain, continuing to supply quality Scottish fish to markets at home and abroad”.
Family-run fishing business Skelwick LLP, which has been providing fishing services to the north east of Scotland for 25 years, operate Aalskere, which is skippered by Iain Harcus.
