Macroalgae harvesting

hoesting-tang-smallThe 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).


Kick-off meeting PROMAC

The PROMAC kick-off was held April 28th – 29th at Scandic Parken Hotel in Ålesund with representatives from research partners, industry and the Research Council of Norway. 


Day 1 opened with a welcome speech from Elisabeth Maråk Støle managing director at Møreforsking and an introduction to PROMAC by project manager Lise Chapman from Møreforsking. This was followed by an introduction to communication in PROMAC held by leader of WP 7 Ana Carvajal from SINTEF Fisheries and Aquaculture. Turid Hiller representative from the Bionær-program at the Norwegian Research Council was up next with a presentation of the Bionær-program and how PROMAC fits in the program. This was followed by a presentation of the industry’s expectations of PROMAC, by the industry network representative Oddvar Skarbø (LEGASEA). Steinar Bergseth (ERA-Net Marine Biotechnology) presented the European perspective of biotechnology and innovation, before Katja Hansen (Environmental Protection Encouragement Agency – Germany) from the advisory board finished the session with a presentation of the idea of a circular bio-economy in Europe.

The next part of the program was a visit to Tafjord Kraftvarme Waste Incinerator at Grautneset. Knut Arve Tafjord held a short introduction about the facilities and all participants travelled by bus to Grautneset, were a guided tour around the plant and lunch was arranged. For lunch Klippfiskakademiet had prepared a variety of different tapas courses with macroalgae, sponsored by Tafjord Kraftvarme. The film crew from TYD joined at the site to film the plant.

Back at the hotel all the partners were introduced with a short power point. The official day was ended with a presentation of the SFI (Centre for Research Based Innovation) “Foods of Norway” by Torunn Mydland (Norwegian University of Life Science). And the General Assembly (GA) held a meeting at the end of the day. A guided tour around Ålesund was arranged for those who wanted to join in the break between the official program and dinner. Dinner was held at Scandic Parken Hotel.

Day 2 was opened by Lise Chapman who welcomed the participants of day 2, mostly research partners. Ana Carvajal followed with a presentation of the whole communication plan for PROMAC. Next on the agenda was an open Management Committee meeting with some interesting discussions. After a short coffee break the partners of the different work packages met and discussed matters of their work packages, and collaboration between the different work packages. The kick-off was ended with a summary by Lise Chapman.
