Nordic network project on the distribution and abundance of seal populations in the North Atlantic, and their socio-economic impact on the fishing industry and other stakeholders

The research & networking project Nordic Seals, or "Nordic network on seal populations in the North Atlantic and adjacent waters", led by Matís, recently came to an end. The project was supported by the Nordic Council of Ministers' working group on Nordic cooperation in fisheries and aquaculture AG fisk.The main goal of the project was to establish a network of stakeholders involved in research on seal populations, and those affected by seals in the area. Thereby facilitating and promoting an active conversation between key stakeholders regarding the distribution and socio-economic impacts of seals on the environment and communities in the North Atlantic, including on fisheries and aquaculture.

Seal hunting was an important industry in many parts of the Nordic countries for centuries, as sealers from Norway, Finland, Greenland, Denmark, Iceland, Russia, and Canada hunted hundreds of thousands of seals every year. This industry came under severe criticism in the 1970s and 1980s, when animal welfare began to take a bigger place in the discussion about the exploitation of wild animals. By the turn of the century, seal hunting had become politically unacceptable, which affected the markets for the products and led to the eventual end of commercial seal hunting. Seal hunting in the N-Atlantic has now been almost non-existent for over two decades. But what effect has this change in the exploitation of seal populations had on the ecosystems and the socio-economic landscape of those affected by changes in the size and distribution of seal populations?

Since the Nordic Seals network was established in 2021, it has collected, analysed and shared information about seal populations in the Nordic regions, and their impact on the ecosystem and human society, for example by:

  • collecting information on seal populations and their distribution in the N-Atlantic, Arctic and adjacent water (e.g. North Sea, Baltic Sea, Skagerrak, Kattegat, etc.),
  • analysing the possible impact of seal populations on the ecosystem, and studying ongoing initiatives to quantify and assess those impacts,
  • analysing the effects of seal populations on the Nordic fishing industry,
  • studying available alternatives to control seal populations, including sustainable utilisation,
  • identifying and exploring potential products and markets for seal products, while considering barriers such as animal welfare, policy and political correctness, food safety and toxins.

The main results of the aforementioned work can now be seen in the recently published report, which can be accessed here.

Other important products of the project are the following:

In the abstract of the final report of the project it is stated that:

As several seal populations have grown in the North Atlantic, Arctic, and adjacent waters, they have become a controversial topic with fishermen and other stakeholders within seafood value chains who claim that they negatively affect commercial fish stocks, catch, product quality and economic viability of the fisheries. Many scientists and conservationists have on the other hand pointed out the lack of understanding of the functioning of seals in the ecosystem. Although seals are known to feed on commercial fish species, research on their effect on fish size and age distribution of prey populations, as well as stock size, is incomplete. More knowledge on the role and effects of seals in the ecosystem is therefore needed. As some seal populations still suffer from hunting that took place in the past, decisions on seal management must be well founded. Bycatch of seals is today the main threat to seal populations in many areas, which must be taken seriously.

Depredations and damage to fishing gear and fish farms caused by some species of seals is well documented. The exact ecological and economic impact of these is however largely unknown. There are ongoing initiatives that aim to fill in these knowledge gaps, but results are largely lacking. The issue of nematode roundworms that are parasites causing quality defects in commercial fisheries, which seals play a major role in distributing as hosts, has been a concern for fishermen. Controlling seal populations was in the past believed to be important to limit nematode distribution and therefore considered vital to safeguard the economic viability of the seafood industries in the North Atlantic.

Research show that the seal species in the N-Atlantic and adjacent waters need to eat a biomass corresponding to 4-6% of their body weight per day to sustain themselves. The number of seals in the area has now reached about 14 million individuals, and therefore it is likely that their consumption of biomass is about three times that of human fisheries in the area. But as mentioned before, knowledge of the effects of seals on the ecosystem and commercial fish species is incomplete.

Seals have a long history as an important food source. Seal meat is nutritious and full of important amino acids, vitamins, and minerals. But they also contain food safety threats, such as nematode ringworm parasites, and bioaccumulated trace elements. The import bans on seal products imposed by the US and EU have made any kind of trade in seal products difficult. But as some seal populations grow in certain areas, the question on potential utilisation becomes more pressing. To answer that question there is a need for more research to better understand the role of seals in the ecosystem, and on how to produce sustainable, safe and stable food or feed ingredients from seals.

Doctoral defense in Chemistry – Rebecca Sim

Next Monday, May 27, Rebecca Sim will defend her doctoral thesis in chemistry at the University of Iceland. The thesis is entitled Distribution of hydrophilic and lipophilic arsenic compounds among macroalgae.

The doctoral defense will take place in the Celebration Hall of the University of Iceland's Main Building at 11:00 a.m. to 1:00 p.m. Opponents will be Dr. Barbro Kollander, senior scientist at the Swedish Food Agency and Dr. Kristmann Gíslason, professional manager of the chemical analysis group at the Icelandic Marine Research Institute. The supervisor is Ásta Heiðrún Pétursdóttir, PhD in chemical analysis and expert at Matís.

The doctoral committee also includes Dr. Guðmundur Haraldsson professor emeritus, dr. Jörg Feldmann, head of the Trace Element Speciation Laboratory (TESLA) at the University of Graz in Austria, and Dr. Karl Gunnarsson, biologist at the Icelandic Marine Research Institute.

The director of defense is Dr. Einar Örn Sveinbjörnsson, dean of the Faculty of Science, University of Iceland.

Rebecca is from North-East Scotland but moved to Iceland in 2020 to study for a PhD. She completed a BSc in Chemistry at the University of Glasgow and an MSc in Analytical Chemistry at the University of Aberdeen. Rebecca currently works as an expert in Matís' chemical analysis group.

The following is an abstract of the essay:
Algae can absorb large amounts of the element arsenic from the sea in the form of inorganic arsenic, which is a known carcinogen. In the algae, arsenic is also detected in the form of diverse organic compounds of arsenic, for example arsenosaccharides and arsenolipids, but organic arsenic species have been considered harmless. However, recent research on arsenolipids has shown that they can be as cytotoxic as inorganic arsenic, and it is possible that arsenosugars have long-term negative effects with regular consumption. There is a lot of mystery about the origin of arsenolipids, but the starting point of their production is believed to take place in algae. Algae are becoming more and more popular in the West. More information on these compounds is urgently needed to fully assess the risks associated with their consumption and to ensure that appropriate regulations are established regarding their maximum levels in food. Samples of red, green and brown algae were collected near Grindavík and Kjalarnes. The samples were thoroughly analyzed for heavy metals and an arsenic analysis was carried out to obtain information on the chemical form of the arsenic. The speciation of arsenolipids is complex and was carried out in selected samples with mass spectrometry HPLC-ICP-M/ESI-MS/MS and HPLC-qToF-MS. In addition, brown macroalgae were divided into biological fractions to determine whether the distribution of arsenic species is uniform throughout the seaweed. Limited information is available globally on algal arsenolipids, so this extensive profiling of them in different species of algae will help elucidate how these enigmatic organic arsenic compounds are formed and where they are stored. The data can also be used for risk assessment of arsenic species in seaweed for human consumption and can therefore influence future food safety legislation.

Whitefish processing and land farming benefit from work in the Accelwater project

Last week, a project meeting took place in Spain in the collaborative project Accelwater, in which Matís participates. Two project managers from Matís, Sæmundur Elíasson and Hildur Inga Sveinsdóttir, attended the meeting and presented, among other things, the aspects of the project they have worked on.

The Accelwater project is about accelerating the cycle of water in the food and beverage industry across Europe, but the main goal of the project is to use value from water and reduce fresh water consumption during food processing. Numerous food producers and research partners are involved in the project, but Matís leads the work package that relates to Iceland, and here the emphasis is on land processing of whitefish and land farming of salmon. In addition to Matís, the Icelandic participants in the project are the University of Iceland's Faculty of Food and Nutrition, Útgerðarfélag Akureyri and Samherji Fiskeldi.

At the workshop, Hildur and Sæmundur presented the latest news about the Icelandic work package. The main news was about the installation of flow and energy sensors in whitefish processing in order to measure changes and achieve both water and energy savings in the processing. There, a master's student from Denmark is working on his final project around this work.

During the land fire, progress was reviewed in experiments with the utilization of sludge for fertilizer production. There is a system that filters the sludge and results in a mass of dry matter that can be used, among other things, in biogas or fertilizer. Experiments with dry bleeding of salmon and the possible use of salmon blood for value creation were also reviewed.

Finally, the results of the life cycle analysis, which is being worked on with the University of Iceland, were reviewed. The water use and environmental impact of the aquaculture industry and feed production are currently being analyzed there using the methodology of life cycle analysis.

In addition to this presentation, partners in the project located in Spain were visited. The meat processing company BETA was visited and the conditions were examined, but they are working to convert waste from the processing into value. MAFRICA's meat processing plant was also visited and they could see the waste treatment process developed in the Accelwater project. The waste/pig excrement is then put through a water purification process and a biogas plant, and the result is reusable water and energy, among other things in the form of biogas.

At the end of the trip, they had the opportunity to see the beautiful Montserrat mountain.

Development of a predictive model to assess the quality of fishmeal in salmon farm feed

Contact

Director of Business and Development

jonas@matis.is

Now the Food Fund project Development of an image and spectroscopic predictive model to assess the quality of fishmeal as an ingredient in salmon farm feed halfway through, but the previous project year ended in the autumn of 2023. This is a joint project of the Association of Icelandic Fishmeal Producers, Síldarvällúnn, Eskja, Ísfélagin, the University of Iceland and Matís. The goal of the project is to develop a NIR (near-infrared spectroscopy) prediction model that enables fishmeal producers to obtain a fast and accurate analysis of the quality of fishmeal as an ingredient in salmon feed.

Most Icelandic fishmeal producers already use NIR to measure the chemical content of the fishmeal, and thus get good indications of its quality. However, the NIR measurements that are carried out today are of limited use when it comes to assessing the quality of the fishmeal for its main use, i.e. as an ingredient in aquaculture feed. If such measurements are to be made, growth and digestibility experiments must be carried out in aquaculture, which are both time-consuming and costly. By developing a NIR prediction model, however, it is possible to shorten the time of the analyzes from many months to a few seconds, and the cost from many millions to almost nothing.

This is not a new approach, as Norwegian feed producers developed such NIR prediction models a few years ago and have used them to assess the quality of the fishmeal they buy. However, these manufacturers have considered their predictive models to be trade secrets, giving them a competitive advantage. By developing and making similar forecasting models available to Icelandic fishmeal producers, they will have the same (or better) information about the characteristics of their production as their customers, and therefore enable them to negotiate prices with their customers on an equal footing. The predictive model will also enable fishmeal producers to evaluate/improve their own production, with information for internal quality control. The database/prediction model will be handed over to the participants (fishmeal producers) towards the end of the project, together with the fact that courses on its use will be held.

As mentioned before, the project will take two years, and that work is now halfway done. The project is scheduled to be completed by the end of 2024.

Abstract

Microbes on the Earth's surface can be released into the atmosphere by wind and associated with events such as volcanic eruptions and dust storms. Before they reach a new surface, they are exposed to various stressful environmental factors that prevent the colonization of a large part of them. The diversity and evolution of low bacterial communities in different environments has been quite well studied. However, little is still known about microbial communities in the atmosphere, their colonization on the surface and what effect such colonization has on the microbial communities that are there. This study is the first to discuss the distribution of microorganisms in the Icelandic atmosphere and especially their colonization in a volcanic environment. Airborne microbial communities from two unique but different volcanic areas, both at sea level and at high altitude, were examined and compared. The research was carried out on the protected volcanic island of Surtsey and at the lava flow on Fimmvörðuhálsi, by analyzing the microbial communities of the atmosphere and their colonization in lava rock after one year. The atmosphere was also studied as an important source for the distribution of microbial communities in the soil and the methods by which microbes manage to withstand the harsh environmental conditions of the atmosphere. Cultivable and non-cultivable microbial detection methods were used to describe and compare the microbial communities. The diversity of uncultivated microbes was analyzed by isolating DNA from 179 samples and sequencing the 16S rRNA gene of the microbes ("amplicon" sequencing). A total of 1162 strains belonging to 40 genera and 72 species were isolated. Of these, 26 strains were probably new species. One new Flavobacterium species was fully described and the resistance of selected strains to atmospheric stressors was investigated. The origin and trajectory of the populations was determined with a special prediction model "source-tracking analysis". Results show that the microbial communities at both sampling sites consisted of Proteobacteria, Actinobacteria and Bacteroides, but the proportion of their numbers was controlled by the environmental factors of each area. The aerial and terrestrial communities were very different, which is reflected in the different environmental aspects of each environment. Interestingly, the bacterial communities in the lava rock at Fimmvörðuhálsi were more or less the same after one year of colonization, compared to a nine-year period, which suggests that the stability of the first settler community is achieved after one year, but that the progress of the community slows down after that. At Surtsey, over 80% of bacterial communities found in lava rock after a one-year period originated from the local environment. The communities showed tolerance to atmospheric stressors, which probably helped them to survive air dispersal and facilitated their colonization of the lava rock. In accordance with previous studies, it was also found that the most influential selection factors were freezing, thawing and cyclic permeabilization of the cells, and that Proteobacteria and Ascomycota seemed best suited to survive such atmospheric stress factors. Results indicate that stress-resistant microbes from the atmosphere are the source of microbes that are the first settlers in the nearby, newly formed environment by forming unique and diverse microbial communities in a short time or less than a year. These results provide important insights into the early stages of microbial colonization and demonstrate the importance of airborne microbial studies to advancing our understanding of Arctic volcanic ecosystems.

Abstract

Surface microorganisms can be aerosolized into the atmosphere by wind and events such as volcano eruptions and dust storms. Before depositing, they experience stressful atmospheric conditions which preclude the successful dispersal of a large fraction of cells. While bacterial diversity and succession on different low-bacterial environments are reasonably well characterized, research on airborne atmospheric communities and the significance of their deposition for community assembly remains poorly understood. This study is the first to address microbial distribution in the Icelandic atmosphere and particularly in their colonization in volcanic environments. We assessed and compared the bioaerosols communities from two dissimilar unique volcanic sites located at sea level and at high altitude, the protected volcanic island Surtsey and Fimmvörðuháls lava field, by analyzing in situ atmospheric microbial communities and communities in lava rocks after one year of exposure time . Additionally, we investigated the air as a significant source for the dissemination of the microbial communities into soil and their potential strategies to withstand atmospheric stresses. Culture-dependent and culture-independent methods were employed to describe and compare these microbiomes. The uncultivated diversity was analyzed by DNA extraction from 179 samples and 16S rRNA amplicon sequencing. A total of 1162 strains were isolated and affiliated to 40 genera and 72 species, with potentially 26 new species. A new Flavobacterium species was fully described and the survival of selected strains against simulated air stress factors was investigated. The origin and dispersion of the isolates was predicted using a detailed source-tracking analysis program.

Our findings reveal that the microbial communities in both sampling sites are dominated by Proteobacteria, Actinobacteria, and Bacteroides, but their proportions were influenced by the unique characteristics of each site. The atmospheric and lithospheric communities showed significant differences, reflecting different environmental pressures from each site. Interestingly, the bacterial communities in the lava rocks of Fimmvörðuháls were similar after one year compared to nine years of exposure, suggesting rapid microbial colonization and slow succession of the community. On Surtsey, over 80% of the bacterial communities that colonized the lava rocks after one year exposure, originated from local surroundings. These communities displayed stress-resistant properties that likely helped their survival during air dissemination from close environments and facilitated their colonization into the lava. Furthermore, in line with previous studies, we observed that the most stringent selection factors were the freeze–thaw and osmotic shock cycles and that the strains affiliated with Proteobacteria and Ascomycota were the best to survive simulated atmospheric stresses. Our results suggest that atmospheric stress-resistant microbes that deposit from local sources in newly formed environments, form unique and diverse communities in a rather short time or less than one year. These findings provide important insights into the early stages of land colonization of microbes and puts emphasis on the important role of bioaerosol research in enhancing our understanding of subarctic volcanic ecosystems.

Natalie's climate project kick-off meeting

On the days 7-10 last november took place in Limoges, France, the opening meeting of the Natalie project, to which Matís is a member. The main focus of the project is to develop NSB's nature-based solutions to monitor and/or respond to the effects of climate change.

Natalie is a five-year project, which will be carried out by 42 participants from all over Europe. Iceland's role in the project is to verify new implementations of nature-based methods for assessing the effects of climate change on coastal areas and their ecosystems. The project is extensive and complex in its entire implementation, and the meeting was aimed at getting everyone to the table, introducing themselves and the parts of the project that each has at their disposal.

During the meeting, the management part of the project was thoroughly reviewed, i.e. what is expected of each of its members. There was also a presentation of all seven work parts of the project (e. work package, WP) together with the presentation of all the 42 parties involved in the project, i.e. their participation in the project and their background.

The meeting days were long but successful as planned. In addition, people managed to talk to each other and get to know each other, which is an extremely important part of such busy projects that cover as long a time as Natalie's proposed five years.

After the meeting, it is clear that there are exciting times ahead as Matís will participate in the development of the evaluation of new solutions to prevent the loss of important ecosystems. The challenges of climate change are numerous, including the threat to ecosystems that support food production, thereby threatening our food security as a nation due to local changes, but also on a global scale.
