The Stehr family will no longer be involved in the day to day running of Clean Seas Tuna after Marcus Stehr retires in April.
Mr. Stehr’s departure from an operational role follows his father, and company founder, Hagen, stepping back from his executive chairman role in late 2009.
Both remain on the board, and Clean Seas said yesterday Marcus had agreed to provide consulting services to the company for two years.
Clean Seas was listed in December 2005 with the ambition to spawn and grow southern bluefin tuna in captivity.
The company has had some success with the process, but not on a commercial scale.
