Is rapeseed meal a good source of feed for salmon?

AVS recently completed the project "rapeseed meal in feed for salmon 2". The aim of the project was to investigate the effect of the incorporation of rapeseed meal into feed on the growth, feed utilization and chemical content of salmon fillets.

Experiments were made with 5 types of feed with different proportions of mixed rapeseed meal and then standard feed for comparison. The initial weight of the fish was 350 grams and the experiment lasted for eight months, during which time the fish quadrupled in weight. The results of the project were numerous, but it stands to reason that the incorporation of rapeseed meal into salmon growth feed for salmon does not appear to have a measurable negative effect on the growth, feed utilization or meat quality of small salmon.

The final report of the project will be treated as confidential until 1 January 2024, after which time it will be possible to access the report on Matís' website.

Thermophilic bacterium isolated from the basaltic subsurface of the volcanic island Surtsey

A team lead by Matís' microorganisms researchers and specialists has recently published a research article in the International Journal of Systematic and Evolutionary Microbiology. The article is called: Rhodothermus bifroesti sp. nov., a thermophilic bacterium isolated from the basaltic subsurface of the volcanic island Surtsey.

The volcanic island Surtsey is the southernmost point of Iceland and it was formed in volcanic eruptions that took place from 1963 to 1967. Surtsey has been protected from human interference since it was formed but has been a subject for many scientific researchers.

The Article was published online late January 2022 and the abstract is as follows:

Novel thermophilic heterotrophic bacteria were isolated from the subsurface of the volcanic island Surtsey off the south coast of Iceland. The strains were isolated from tephra core and borehole fluid samples collected below 70 m depth. The Gram-negative bacteria were rod-shaped (0.3–0.4 widem wide, 1.5–7 longm long), aerobic, non-sporulating and non-motile. Optimal growth was observed at 70 ° C, at pH 7–7.5 and with 1% NaCl. Phylogenetic analysis identified the strains as members of the genus Rhodothermus . The type strain, ISCAR-7401T, was genetically distinct from its closest relatives Rhodothermus marinus DSM 4252T and Rhodothermus profundi PRI 2902T based on 16S rRNA gene sequence similarity (95.81 and 96.01%, respectively), genomic average nucleotide identity (73.73 and 72.61%, respectively) and digital DNA – DNA hybridization (17.6 and 16.9%, respectively). The major fatty acids of ISCAR-7401T were iso-C17:0, anteiso-C15:0, anteiso-C17:0 and iso-C15:0 (> 10 %). The major isoprenoid quinone was MK-7 while phosphatidylethanolamine, diphosphatidylglycerol, an unidentified aminophospholipid and a phospholipid were the predominant polar lipid components. Based on comparative chemotaxonomic, genomic and phylogenetic analyzes, we propose that the isolated strain represents a novel species of the genus Rhodothermus with the name Rhodothermus bifroesti sp. nov. The type strain is ISCAR-7401T (= DSM 112103T= CIP 111906T).

The subject of this report is a discussion of waste in the wood chain of vegetables and ways to reduce it. The work was part of the project Increased quality, shelf life and less waste in the value chain of Icelandic vegetables, but the project was funded by the Food Fund in 2021.


The topics were as follows: (1) An overview of existing knowledge on food waste in Iceland was compiled. (2) Observations were made on supply chains and selected stores. Temperatures were measured in store refrigerators and sirites were used to record temperatures during the transport of vegetables. The parties concerned have received suggestions and had the possibility of corrections. (3) A survey of attitudes towards vegetable waste was carried out by parties outside the vegetable value chain. Information from all parties was compiled and solutions and innovation possibilities were identified. (4) A test was carried out on the processing of unsaleable vegetables and various methods for such utilization were identified.


In this report the waste in the Icelandic vegetable value chain is discussed
and possible solutions are suggested. The work was a part of a project on
improved quality, shelf-life and reduced waste in the Icelandic value
chain.
The following aspects were studied: (1) State of knowledge regarding food
waste in Iceland. (2) Examinations and temperature measurements under
transportation of vegetables and in supermarkets. (3) Investigation of
views towards waste of vegetables. (4) Possible product development
using vegetables otherwise wasted.

Workshop on salmon farming - the report has been published

A workshop on salmon farming was held in Ölfus Cluster's premises in Þorlákshöfn on 27 October 2021. The topics of the meeting were issues that are important to salmon farming in the sea and an attempt was made to identify all the main and latest solutions in those areas.

Discussions included preventive measures against salmon lice, innovations in feed production where the utilization of feed is maximized compared to the environment of aquaculture in the sea, and juvenile farming in controlled conditions on land; so-called Recirculating Aquaculture Systems (RAS). Scholars and experts in these fields from Iceland, the Faroe Islands, Norway, Denmark and Finland gave presentations on the latest trends and trends in the meeting's topics. The project was funded by AG Fisk, a Nordic grant fund, and led by the following scientists, experts and farmers from all the Nordic countries.

  • Gunnar Thordarson, project manager, Matís, Ísafjörður, Iceland
  • Björgolfur Hávardsson, NCE Seafood Innovation Cluster AS Norway
  • Gunnvør á Norði and Jóhanna Lava Kötlum, Fiskaaling, Faroe Islands
  • Kurt Buchmann, Department of Veterinary and Animal Sciences, University of Copenhagen, Frederiksberg, Denmark
  • Henrik Henriksen, The Danish Aquaculture Organization, Aarhus, Denmark
  • Marko Koivuenva, Finnish Fish Farmers' Association, Helsinki, Finland.

About 60 people attended the meeting, which began early in the morning and lasted until the middle of the day. The presentations of the performers who informed the participants about all the latest things that are happening with these important issues in fires in sea cages were very well received. There was great satisfaction with the performers and the presentations that were made, and a lot of questions and comments to them.

 The workshop was held in connection with Lagarlíf, which is a conference on aquaculture and breeding in Iceland, which was held on 28-29 October. It was almost possible to hold the workshop and conference due to disease control measures, but a short window was formed during this time to hold these meetings. As usual, people got off the train who were supposed to be on duty due to quarantine, but in time they managed to get other specialists in to fill the gap.

The project was linked to Matís' website, where you can access all the issues of the meeting. The page is accessible here: Nordic Salmon.

Following the meeting, a report was written on the performers' presentations and an introduction to the relevant parties: Nordic Salmon - Report.

The Krakkakropp project nominated for the President of Iceland's Innovation Award

The Krakkakropp project was nominated for the President of Iceland's Innovation Award. The project was funded by the Student Innovation Fund and was carried out in connection with the project "Improved quality, shelf life and less waste in the vegetable value chain" at Matís. Krakkakropp is ready-made baby food made from Icelandic vegetables.

The project was carried out by Arnkel Arason, Sigrún Anna Magnúsdóttir and Vaka Mar Valsdóttir, students in food science at the School of Health Sciences at the University of Iceland. The supervisor was Ólafur Reykdal, project manager at Matís.

The President of Iceland's Innovation Award was presented on 10 February. The award went to the project "Better intensive care with a data monitor. "

The President of Iceland's Innovation Award is given annually to those students who have done outstanding work in solving a project that was funded by the Student Innovation Fund the previous summer. 

Krakkakropp was among 6 projects nominated for the award and received special recognition. This is considered a very good result as a number of projects were considered. Following the project, students have now founded the company Sifmar ehf. The company has also received additional grants, students have participated in business and marketing accelerations and Landsvirkjun has invested in the company.

Further information about the project:

Krakkakreistur and Krakkakropp: Icelandic baby food.

The project was carried out by Vaka Mar Valsdóttir, Sigrún Anna Magnúsdóttir and Arnkel Arason, students in food science at the School of Health Sciences at the University of Iceland. The supervisor was Ólafur Reykdal, project manager at Matís. The trigger for the project was a big hole in the market, but at the moment no ready-made Icelandic baby food is available. At the same time, imports of foreign baby food increase by hundreds of tonnes annually.

Iceland has green energy, sustainable production, clean water, excellent raw materials and the negligible use of pesticides in vegetable production. Therefore, we in Iceland have full capacity to produce good and healthy baby food for our children.

The students' ideal was to use their learning experience to develop prototypes of Icelandic baby food that could be produced responsibly with environmental considerations and hygiene in the forefront. Children's public health is an urgent problem, but approx. a quarter of Icelandic children measure their ideal weight. It is therefore important to respond with healthy and suitable solutions for families with children. Food waste has a huge impact on climate change, but about 45% of the world's vegetables are considered to be wasted. In collaboration with Sölufélag garðyrkjumanna, the students developed baby food from, among other things, vegetables that are either too small, too big, curved or broken. Such vegetables would not be useful in traditional sale products but are otherwise of perfect quality and therefore ideal for the production of mashed and dried baby food.

At the end of the project, five prototypes remained Kids' circles - suitable baby food in bags and three prototypes of Kids body - pediatric nasal congestion.

Following the project, students have now founded the company Sifmar ehf. The company has also received additional grants, students have participated in business and marketing accelerations and Landsvirkjun has invested in the company. During the day at Sifmar ehf. is an ongoing financing process so that safer and more environmentally friendly production can be offered in this country.

It can therefore be said with truth that Icelandic production, sustainability, children's public health, combating food waste, positive environmental impact, agriculture and technological development are all issues that affect the project and go hand in hand with the United Nations' global goals.

Nordic co-operation

The project was supported by AG-Fisk and managed by six people with knowledge on the subjects or relation to the industry. The group came from Iceland, Norway, Faroe Islands, Denmark and Finland.

The workshop aimed to gather experts in specific fields of salmon farming in the Nordic countries. Areas of uppermost importance for the Nordic salmon aquaculture were identified as; salmon- and sea louse challenges, optimal feed composition sources, and production of large smolts.

Four specialists in sea- and salmon louse and preventive measures against these parasites came from three countries, Iceland, Faroes Islands and Norway. Four experts in new sources and optimal compositions of feed for different environments came from three countries, Iceland, Norway, and Finland. And tree experts in smolt hatcheries (RAS) discussed large smolts production from two countries, Iceland, and Denmark. 

There were 60 people at the meeting held in Olfus Cluster in Thorlakshofn, a fisheries community in Sothern Iceland. Olvus Cluster is a collaborative project by entrepreneurs planning large-scale production of land-based salmon farming. 

The guests of the meeting had it in common of working in the aquaculture business, serving the industry or being a public body.
