On a sunny 28.June a team from SINTEF went out to do the last growth registrations and harvest biomass of Saccharina and Alaria. The Saccharina season has been good and similar to last year with up to 8 kg/m cultivation rope, whereas for Alaria the growth was disappointing with only 1,5 kg/m – only half of last year.

 

We have now a large number of samples for analysis of protein and amino acids at SINTEF, iodide at NIBIO, polyphenols at CEVA and arsenic and heavy metals at MATIS. Not at least, we brought 450 kg Saccharina biomass back to town for processing into feed proteins for the feeding trials that NMBU will be responsible for.
