In seven years, the Norwegian fish farmer Hardingsmolt has sent more than 11 million post-smolts through its floating closed containment pens into the sea, and after the introduction of a new winter sore vaccine, the last six million have had a survival rate of 99%.
This was stated by general manager Frode Sandven during the seminar “From decline to recovery” about closed post-smolt production in the sea, organised by Ocean Tales during the HavExpo trade show near Bergen in Norway this week.
The company received a development permit together with Merdslippen seven years ago, and has since produced post smolt in closed cages at sea.
