Police Scotland have confirmed that the body recovered on Thursday is that of the 35-year-old kayaker Dominic Jackson.
A man's body was discovered in the water near Lybster at around midday during air searches by the Police Scotland helicopter. Wick lifeboat was launched to assist with the recovery.
Inspector Kevin Goldie, who helped lead the search, said: "I can sadly confirm that the body recovered on Thursday has been identified as Dominic's. His family has been made aware and we are supporting them at this very difficult time.
"This is not the outcome anyone wanted, and our thoughts are obviously with all of Dominic's family and friends.
"I would like to take this opportunity to thank members of the community and volunteers for their support. I know it was a great source of comfort to his family and came as no surprise given the community spirit in the area.
"I would also like to express my gratitude to the teams who carried out painstaking searches both here in the North East and further north. The terrain is challenging and the dangers of operations like this can never be underestimated."Thank you also to members to the public who provided Police with information as we tried to piece together Dominic's last movements. Your information was invaluable."
