The first harvest of cultivated biomass was done 20th of May. The small sporophytes was deployed on the site the 23rd of February 2015. The sporophytes was cultivated at three depths; 2, 5 and 8m. The cultivation period by then was 68 days and since deployment the sporophytes had grown from ca 0,5 cm to a range from 63,8cm at 8 m cultivation depth to 74,6cm at 2m depth (average 68,5cm) for Saccharina latissima and 66,8cm at 8 m cultivation depth to 87,6cm at 2m depth (average 77,2cm) for Alaria esculenta. Samples for biochemical analysis and microbiology was harvested, processed and stored for further analysis. The abundance of epiphytes was quite low at this point, no bryozoans, but traces of filamentous algae at the tips of the blades. On A. esculenta sporopylls were present but not fertile.
The June harvest was done 18th of June, with harvest of most of the biomass that was cultivated. In total ca 1 tonn of S. latissima, and ca 200 kg A. esculenta was harvested and distributed to partners at SINTEF Energy and SINTEF Materials and chemistry. The samples for biochemical analysis and microbiology were harvested, processed and stored. Sporophytes were harvested at three cultivation depths, 2, 5 and 8 m. Size for S. latissima ranged from 60,25cm at 8 m cultivation depth to 85,6cm at 5m depth (average 70,4cm). Size for A. esculenta ranged from 65,5cm at 8 m cultivation depth to 71,7cm at 2m depth (average 68,6cm). Cultivation period in sea for both species was 115 days. The abundance of epiphytes was higher at this point with bryozoans, spread on all blades, and some epiphytic filamentous algae at the tips of the blades. On A. esculenta sporophylls was present, but not yet fertile. Representatives from SINTEF Energy joined the harvest this time, and the boat with skipper was provided from AquaCulture Engeneering (ACE). The cultivation site is owned by Seaweed Energy Solution (SES).
