Fish news recently published an article discussing an exciting project that was worked on at Matís in collaboration with chef Dóra Svavarsdóttir and it was about experiments with dry emaciation or so-called dry-age effect on fish which is considered promising.
The article talks to Dóra, who worked on the research project together with Cecile Dargentolle, project manager in the field of value chain at Matís, specializing in fish. The dry-age method of action is well known and has been applied to meat to make it softer and more tender, but in this study it was used on fish to keep it fresh longer and the texture becomes firmer.
In the project, experiments were carried out with whole fish but also with fish fillets. They specifically looked at one white fish species and one oily freshwater species and chose haddock and char. The goal was to find the right temperature and humidity to increase the shelf life of the fish in a completely controlled environment.
With this dry-age effect, it is not at all a case of dried fish, like hard fish, or that the fish will be shriveled, as there is no fermentation involved. The result is fresh fish that is cooked in the traditional way and can become an exciting ingredient for a variety of restaurants.
The project was carried out with a grant from the Food Fund, and they are now aiming to apply for a grant for a follow-up project in order to conduct further research and prepare guidelines for this method of action for different types of fish, which would then be accessible to more people.
On the 5th-6th Last February, the kick-off meeting of the BIO2REG project took place. The project aims to transform large industrial areas into a circular economy.
Jülich Forschungszentrum in Germany leads the project and there are a total of 9 participants, including Matís. Iceland's role is to hold a specialized workshop or so-called Expert Workshop in this country where we present, together with our partners from RISE in Sweden, what has gone well in Iceland when it comes to adopting a circular economy and what should be avoided.
The organization of the project, the role of each participant and what is to be done in the coming months and years were reviewed at the meeting. BIO2REG will pave the way for economic operators to actively initiate and shape the transition to environmentally friendly production based on a region-to-region approach. There are exciting times ahead and we are very much looking forward to having foreign experts visit the Expert Workshop at the beginning of September.

The NextGenProteins project ended at the end of 2023. It is the largest project that has ever been funded by Matís, and work on it lasted from 2019. One of the final products of the project is brochure where the main results of each part of the project are reviewed and it is now available as a pdf. form on the NextGenProteins website.
The NextGenProteins project was funded by the Horizon 2020 fund and aimed to develop, optimize and optimize the production of three sustainably produced neoproteins, and validate their use in various foods and feeds. The proteins that were examined in the project were insect proteins made from by-products of food production, a single-cell protein that is a yeast mass that thrives on sugars from forestry products, and microalgae that are grown largely on CO2 emissions from geothermal energy production.
The aim of the project was, among other things, to examine the government's regulations and policies when it comes to new protein sources, analyze production obstacles and submit strategic proposals to simplify and change the government's regulations and policies towards a more sustainable food system. NextGenProteins also aimed to produce high-quality, safe, nutritious and sustainable protein sources by utilizing industrial by-products that are traditionally wasted.

Research and experiments were carried out to examine the possibilities of using these proteins in various food products and animal feed. Market research and consumer surveys were also carried out as well as sensory evaluation of products containing the new proteins. The sustainability of new protein sources was also examined and compared to more traditional protein sources as well as their environmental and economic impact, production efficiency and resource utilization.
All the main goals of the NextGenProteins project were achieved and such success can pave the way for innovation and new solutions to the challenges facing the current world food system. The production of the proteins examined in the project has less negative environmental impact than most traditional protein production. It is important to take that factor into account when thinking about how to meet the increased demand for protein production along with increased population growth in the world.
In the attached booklet, which is in English, the supervisors of each part of the project review the main results. In addition, Birgir Örn Smárason, professional manager at Matís and project manager of NextGenProteins, tells about his experience of the project work and its outcome.
A prototype for a Responsive Fisheries Management System (RFMS) was developed in the context of the European FP7 project EcoFishMan and tested on the Portuguese crustacean trawl fishery. Building on Results Based Management principles, RFMS involves the definition of specific and measurable objectives for a fishery by the relevant authorities but allows resource users the freedom to find ways to achieve the objectives and to provide adequate documentation. Taking into account the main goals of the new Common Fisheries Policy, such as sustainable utilization of the resources, end of discards and unwanted catches, a management plan for the Portuguese crustacean trawl fishery was developed in cooperation with the fishing industry, following the process and design laid out in the RFMS concept. The plan considers biological, social and economic goals and assigns a responsibility for increased data collection to the resource users. The performance of the plan with regard to selected indicators was evaluated through simulations. In this paper the process towards a RFMS is described and the lessons learned from the interaction with stakeholders in the development of an alternative management plan are discussed.
The reformed Common Fisheries Policy (CFP), adopted by the European Union in 2013, aims to achieve sustainable exploitation of marine resources. Beyond the mainstream of stakeholders' engagement, the literature increasingly calls for shared accountability in fisheries management. In such scenarios, identifying stakeholders' insights becomes critical for a successful design of innovative management approaches. This paper analyzes how the stakeholders perceive a results-based management system for four fisheries in different European sea-basins as well as at a pan-European level. The results indicate a need for adaptive spirit participatory management approaches, building on regional adaptations within transparent and plural frameworks for fisheries. To succeed, the system should explicitly address its associated public and private costs; neither participation nor accountability comes for free.
Horticultural farms produce a huge amount of by-products that can be used in a variety of productions. Leaves can be used in spice mixes and fiber can be extracted from them to be added to foods. Antioxidant activity was measured in various by-products and it was found that rose cuttings can be used in cosmetics such as facial creams. This is stated in the recently published final report of the project Valorisation of side streams from Icelandic horticulture which Matís led and finished at the end of 2023. The project was carried out in collaboration with the Farmers' Association of Iceland and Orkídea with a grant from the Food Fund.
The aim of the project was to explore the possibility of using diverse by-products from gardening as ingredients for food, nutritional supplements or cosmetics. The side products under investigation were cucumber and tomato leaves, leaves of outdoor cauliflower and broccoli as well as leaves and stems from floriculture. It was also examined whether the use of second-class carrots and potatoes could be improved. All this was studied with a view to increasing the value of vegetable production, improving utilization and increasing sustainability.
Nutritious leaves and low heavy metal concentration
It was surprising how much various nutrients were measured in the side products. Significant amounts of fiber were measured in leaves, stems and carrot grass. The diet of Icelanders often contains too little fiber, but it would be possible to use these substances to improve it. The by-products were generally found to be rich in minerals, particularly potassium, phosphorus, magnesium, calcium and iron. Heavy metals were not measurable or their concentrations were extremely low. These results encourage the utilization of by-products in food. When using new products for food, however, food safety must always be considered, as some plants contain unwanted natural substances to protect the plant. When plant parts have not previously been used for human consumption, it is necessary to check which rules apply to food.
Premium raw materials with the right processing methods
In the project, freeze drying was used to pre-process the raw material for various product development. For example, a special spice mix containing freeze-dried leaves of cauliflower and broccoli was created for meatballs to improve both the taste and wholesomeness of minced meat. The product concept is that the consumer only needs to mix one portion of spice mixture against 600 grams of raw mince and one egg, then it is possible to form buns and fry. This is a simple, nutritious and tasty dish with very little effort.
Deep-fried carrot strips could be a premium product to top off fancy dishes, as a snack or side dish. In the project, experiments were carried out with this processing method, and lightly salted, deep-fried beet strips turned out to be the most delicious. The taste was roasted/roasted, slightly bitter and reminiscent of coffee bean notes. The texture was crispy and the taste extremely delicious. Comparable products on the market are, for example, fried onions and potato straws (pik-nik).
Rose petals and branches with unexpected functions
Exciting opportunities lie in the use of rose petals and rose branches in skin care products, as the antioxidant activity is high in these side products of gardening that are usually thrown away. Rose leaves and branches had the highest antioxidant activity compared to leaves of cauliflower, broccoli, tomato and cucumber. It is therefore an extremely interesting future project to create skin care products with this ingredient and to better measure the effectiveness and conduct consumer tests.
Since 2005, the North Atlantic Seafood Forum (NASF) has been an annual event where managers and stakeholders in the fishing industry and aquaculture meet in Bergen to learn about the main innovations and compare books. This time, NASF will be held on March 5-7. and about 1000 people are expected to attend the event.
This March, NASF will be held for the 19th time, and then managers, investors, equipment manufacturers and other stakeholders in the fishing industry and aquaculture will flock to Bergen to attend the conference. The program this year is looking particularly exciting and has been published on the conference's website nor-seafood.com. The program is divided into 20 seminars and around 200 presentations will be held.
As often before, Icelandic companies and individuals occupy a large place in the program. In recent years, fewer people have come to NASF than they want to, as this is a unique opportunity to meet all the key managers and influencers in the fisheries and aquaculture industry in one place, and hear about the latest developments in the industry. Accommodation in Bergen is going fast during the event, so we encourage people to register early. Registration is taking place here.
Those who want to learn more about the event can contact jonas@matis.is or by phone 4225107.
The genetics group at Matís carries out, among other things, genetic analysis and research on salmon, both farmed and wild. Sæmundur Sveinsson is the head of genetics and he has looked at the life cycle of the Icelandic salmon and its genetic diversity by water area, genetic analysis of salmon from sea hog farming and genetic analysis of salmon for so-called fish farming to name a few.
Icelandic salmon stocks
It is believed that wild Atlantic salmon have been in Iceland since the end of the last Ice Age, or for about 10,000 years. The life cycle of salmon has interesting consequences on the genetics of the species, but salmon spawn in fresh water, the fry live in rivers for 2-4 years and then go to sea. Adult, sexually mature salmon then return to the same river they grew up in after a year or two at sea, to spawn. A salmon that spends one year in the sea is called a small salmon, and a salmon that spends two years in the sea is called a large salmon. This behavior of the salmon, to seek out a nursery river for spawning, is partly determined by certain genes or genes. This life cycle means that populations in rivers are quickly genetically different from each other.
The life cycle of salmon and this genetic differentiation between populations means that the origin of salmon can be traced to rivers and lakes through genotyping. Salmon in Iceland is therefore extremely diverse and there is a great deal of genetic diversity within - and between water areas.
The Institute of Marine Research worked on research on the population genetics of Icelandic salmon, in collaboration with Matís, in the years 1990-2017, which showed precisely the great genetic differences between water areas and parts of the country. It is extremely important to preserve this diversity, but overall the genetic diversity of species is declining globally. In addition to this, salmon caught in the sea, mainly as bycatch from mackerel fisheries, were traced to rivers of origin. Those analyzes revealed that most of the salmon on Iceland's coast in summer turned out to be from continental Europe and Scandinavia.
Genetic diversity is essential to the existence of species and enables them to adapt to changes in the environment. These changes can be diverse, from changes in temperature or other environmental factors to new diseases. Global climate change will undoubtedly exaggerate fluctuations in the weather here in the Arctic, and therefore it has never been more important to preserve biological and genetic diversity in Iceland's biosphere.

Brush salmon
For years, Matís has carried out genotyping analyzes of salmon. Streak salmon are fish that have escaped from sea pen farming and are then caught in rivers or the sea. Aquaculture inevitably involves the risk of farmed salmon escaping from the pens, but it is safe to say that no one wants this to happen and farm companies take various measures to prevent hatchery. In Iceland, a very efficient and good system is in place to keep track of the origin of salmon caught in rivers. It is a legal obligation to return all salmon that are caught to the Norwegian Fisheries Agency and/or the Norwegian Fisheries Agency. Matís receives a sample of the salmon for genotyping, which Hafró then uses to trace the origin of the fish, i.e. from which sea pen he escaped.
This system is based on the fact that Matís also genotypes all the broodstock used to produce fry in sea bream farming in this country. This data is used to perform paternity analyses, but all fish in a given pen have the same father, so their origin can be traced.
Sea urchins in Iceland
In August 2023, the Norwegian Food Agency, MAST, announced a large spill from a pen in Patreksfjörður. What was particularly serious about that streak was that most of the salmon caught turned out to be mature. That means the risk of serious genetic mixing is considerable. Matís received over 500 samples for analysis this fall.
Fish farming
In the fall of 2023, Matís began offering genotyping analyzes of salmon for fish farming. Fish farming refers to the raising of juveniles and juveniles and spawning from wild fish from the river in which the effort is being made to increase the number of fish and fishing. Matís' staff works very closely with the Norwegian Institute of Marine Research's experts in the organization's freshwater sector.
The Norwegian Fisheries Agency and Hafró agree that it would be very bad for salmon populations if farmed fish entered a hatchery and were used for fry or roe production. Salmon that have escaped early from a fire, i.e. when they were small, have very few visible signs of fire, and therefore it is not always possible to rely on the diagnosis of farmed salmon based on appearance. Genotyping is a powerful tool for identifying potential farmed salmon that could be included in fish farming. In autumn 2023, Matís carried out these analyzes for five fishing companies to ensure that only wild salmon would be used in fish farming.
A podcast about genetic analysis of salmon in Iceland
Sæmundur Sveinsson was an interviewer in Matvælinu, Matís' broadcast on research and innovation in food production these days. In the episode, he talks about genetic analyzes of salmon in Iceland over the years and especially the research that his professional group is currently working on. Sæmundi's song deals with these issues in an easy-to-understand and entertaining way, so it's safe to recommend listening!
