Press Room Study reveals candidate genes to improve Atlantic salmon fatty acid composition through selective breeding St. Andrews, New Brunswick, Canada – January 7, 2025 Most are familiar with the term ‘fatty acids’ from widespread media coverage and various recipe/health publications given their requirement for normal cellular development and other biological functions. There are three categories of naturally occurring fatty acids: saturated FAs (SFAs), monounsaturated FAs (MUFAs), and polyunsaturated FAs (PUFAs). Perhaps the most famous of the PUFAs is omega-3 – a member of the n-3 and n-6 fatty acids, which humans are unable to produce on our own and must acquire from our diet. These two groups of essential fatty acids provide opposing health benefits with n-3 enhancing anti-inflammatory properties important for wound healing and reducing the risk of certain diseases and cancers while the pro-inflammatory properties of n-6 are important to protect the body against certain pathogens, infections and injury. Marine fish species, including Atlantic salmon, are well known to be major dietary sources of nutritional and digestible fatty acids. Surprisingly, there have been limited studies globally focused on fatty acid heritability and genomic structure in Atlantic salmon. These attributes have never been reported until now for North American-origin Atlantic salmon given its different number of chromosomes compared to its European-origin counterpart. Researchers from Huntsman Marine recently published results from a study that quantified 35 fatty acids and searched for candidate genes associated with each of them from Atlantic salmon fillets sampled following commercial culture of the fish. “Common Atlantic salmon marketing efforts focus on its high nutritional value, including as a source of essential fatty acids such as omega-3, and we wanted to determine whether any of these fatty acids were heritable and associated with specific genes to allow for more efficient selective breeding in the future,” explained Dr. Barbara Langille, Huntsman Marine Associate Research Scientist and lead author of the recent publication in the international peer-reviewed journal BMC Genomics . Under the direction of Huntsman Marine, Atlantic salmon families were created in a partial factorial design using 56 females (dams) and 38 males (sires) as part of a commercial breeding program. All families were combined post-hatch then communally reared in a commercial hatchery before stocking approximately 11,500 fish into a single sea cage for commercial grow out until harvested. A fish fillet portion from a sub-set of 208 salmon representing 60 families were sampled and shipped to the Agriculture and Agri-Food Canada-Lacombe Research and Development Centre (Lacombe, Alberta) to quantify 35 fatty acids from each fillet and five calculated traits (SFA, MUFA, PUFA, n-3 and n-6). The total amount of fatty acids in an Atlantic salmon fillet had a wide range between 0.04 and 41.3 mg per gram of flesh. Three fatty acids were present in the largest quantities with palmitic acid (a SFA), oleic acid (a MUFA) and linoleic acid (a PUFA) combining to account for almost 70% of the total fatty acid content of the salmon fillets. In contrast, 19 other fatty acids were present in trace amounts and accounted for less than 0.5% of the total fatty acid content. Based on the study results, Atlantic salmon is a better source of PUFAs compared to other livestock animals and contains a more balanced contribution across all fatty acids compared to other fish species. The wide range in specific fatty acid content was reflected in their moderate to high genomic heritability suggesting that selection for improved fatty acid content is possible for most all fatty acids within a breeding program. An important observation from the study was that bled weight and total fat both had a high positive correlation to fatty acid content. This is important since weight (growth) is often an important trait of interest within family-based breeding programs and selecting for growth should therefore also provide meaningful benefit to the fatty acid content of cultured Atlantic salmon. The same genomic peak for three fatty acids was present on Chromosome 23 (including γ-linoleic acid, stearidonic acid and dihimo-γ-linolenic acid). Three genes – sin3b , acbd6 and fads2 – coincide with this chromosomal location and functionally involved in lipid metabolism. Five other fatty acids were associated with genetic markers on different chromosomes that have genes associated with fatty acids and adipose cells. Otherwise the vast majority of studied fatty acids had no clear association with any specific chromosomes or genes. These results suggest fatty acid composition in Atlantic salmon is generally a polygenic trait that may be controlled by many genes of small effect with a few major genes. The few genes identified in the publication are ideal candidates for future functional studies as it relates to fatty acid composition. “We are pleased with results from this study as they provide important baseline data related to fatty acid content in Atlantic salmon at a time when the industry continues to make considerable diet formulation improvements,” concluded Langille. “Atlantic salmon provides consumers with a highly nutritious source of essential fatty acids and now we also better understand how selective breeding may be used to increase these dietary benefits in the future.” The research publication was co-authored by researchers at the Agriculture and Agri-Food Canada Lacombe Research and Development Centre (Lacombe, AB), Mowi Genetics AS (Bergen, Norway) and Tri-Gen Fish Improvement Ltd. (Lacombe, AB). The study was funded by the Atlantic Canada Opportunities Agency (ACOA) Atlantic Innovation Fund, New Brunswick Innovation Foundation (NBIF) Research Innovation Fund, Genome Canada & Genome Atlantic, and industry partners.

Press Room Micro- and nano-plastic particle research needs urgent improvement for effective biomonitoring and risk assessment purposes St. Andrews, New Brunswick, Canada – February 4, 2025 Micro- and nano-plastic particles (MNPs) in the ocean environment and our aquatic food supply is quickly becoming one of the most pressing environmental and public health issues of our time. This level of importance is also reflected in the increasing attention given by the research community and resulting large body of scientific literature over the last decade. Unfortunately, there is a general lack of adherence to accepted guidelines for how to conduct and report this research, especially to increase its value for effective biomonitoring and risk assessment purposes – using living organisms to assess the quality of the environment. Huntsman Marine researchers, along with a colleague from ExxonMobil Biomedical Sciences Inc., completed an initial literature survey within various scientific databases for the period of 2017 - 2022, resulting in 409 applicable biomonitoring papers identified for further systematic review. Each of these were then scored using a previously published 10-category quality criteria rubric that assessed whether the publication included sufficient detail for: sampling method and strategy, sample size, sample processing and storage, laboratory preparation, clean air conditions, negative controls, positive controls, target component, sample treatment, and polymer identification. “On the plus side, the general quality of MNP study design appears to be improving with time,” notes Dr. Benjamin de Jourdan, Huntsman Marine Research Scientist and lead author on the published results in the peer-reviewed journal Science of the Total Environment. “However, deficiencies still occur in reporting study results that affect relevance and reliability for biomonitoring purposes with more effort needed to improve the scientific body of knowledge.” Biomonitoring studies are essential to quantify chemical and particle exposures while also allowing comparisons across all ocean regions and track changes over time. Biomonitoring also provides a means to assess the effectiveness or limitations of various technological, regulatory or policy interventions aimed at reducing the presence of a contaminant in the environment. Researchers therefore have a responsibility to carefully design biomonitoring studies and ensure their methods are fully described within publications to ensure results are best able to aid in the decision-making process. There is certainly a deluge of MNP research published each year but only about 100 are published annually meeting the relevant and reliable inclusion criteria used in this critical review. Essentially all ocean regions were included but with the greatest focus nearly equal from the North Pacific Ocean, Mediterranean Sea and North Atlantic Ocean. An impressive number of 1,243 unique species were included in the 409 reviewed papers with the overwhelming majority being fish followed by crustaceans and bivalves. The authors aimed to be completely transparent in their scoring process as part of their review. “Reviewing over 400 papers was no easy task and we made the scores for each paper available to view online,” explained de Jourdan. “This transparency ensures that others can see how we derived the scores and use them as a training set for future evaluations.” Some key observations from the critical review include: 23% of the research units had the lowest score possible for its description of sampling methods, such as gear type, sampling location and mesh size. 22% did not describe appropriate sample processing and storage methods following field collection. 20% were published without any acknowledgement that measures were taken to protect against sample contamination, such as clothing protection or use of PPE, while processing within the laboratory setting. 48% of reviewed studies did not note processing samples in clean air conditions in the laboratory (e.g., laminar flow cabinet or in a ‘clean room’ setting) to assure the high likelihood of contamination did not occur, which is an improvement from the 90% of studies failing this criteria previously. 86% of research units did not include a positive control or perform a recovery study. Only 24 of 409 papers included this crucial step, which is unfortunately consistent with an earlier 2018 assessment of biomonitoring studies. Scores from the initial 10 assessment criteria were applied to a two-step gateway review to determine overall reliability of each publication for biomonitoring purposes. First, each publication was assessed by giving more weight to whether specific polymers were identified “…as the core objective [of a biomonitoring study] is to develop quantitative relationships between biota and their environment.” In doing so, 108 of the 409 reviewed publications were excluded from further analysis given their limited quantitative utility for biomonitoring and risk assessments. The remaining 301 papers were assessed against a second gate on whether a quantitative relationship between the biota and external environment (matrix) could be achieved from the data reported in the publication. Here, studies that did not include a paired environmental sample (sediment and/or water) were excluded, further reducing the number of papers to 73. Only 32 of those papers had greater than a 50% score for reliability. Just 8% of the 409 publications reviewed met the criteria for reliability, utility for biomonitoring, and informing ecological risk assessment. These results clearly highlight the urgent need for more robust, methodologically sound studies for biomonitoring as a valuable tool but one that requires strict adherence to standardized methods and reporting. The publication finishes with a series of recommendations targeted towards journals, reviewers, funders and researchers. de Jourdan concludes, “We are encouraged to see that the research community is consistently improving with the methods used and described within their publications related to micro-and nano-plastic biomonitoring studies. There is still considerable work to be done but we hope that our recommendations will ensure the greatest utility of research results for effective decision-making and adoption of mitigation measures.” The biomonitoring publication review effort was funded by ExxonMobil Biomedical Sciences Inc.

I have been so passionate about marine biology for so long that I was quite nervous. I didn’t know if I would actually love it as much as I thought I did once I started doing the hands on stuff. But it was quite the opposite! It turned out to be my own little marine biology heaven where I became more and more passionate with everything we did. I had teachers who were passionate and willing to answer all and any questions I had, I was with a group of equally passionate youth who were as willing to learn as I was and who helped create a space where no one was judged on what they knew or didn’t know. And I got a FULL hands-on glimpse into what marine biology might be all about. From digging up worms, to looking at tiny plankton, to beach cleanups and fish dissections, I loved it all!” Kea McKay, ark Cat "Ever since I was a child, I knew I wanted to be a marine biologist – Huntsman helped make my ambition a reality at a young and influential stage in my career.

Press Room Huntsman Marine research expand possible options for oil spill clean-up response in Atlantic Canadian waters St. Andrews, New Brunswick, Canada – February 18, 2026 Canada has vast ocean space with high levels of offshore oil production and transportation activities but few options to mitigate the impacts associated with an oil spill within our coastal waters. Surface collecting agents (also called herding agents or herders) may assist in removing spilled oil by controlling its spread across the water surface to facilitate mechanical removal or aid in situ burning operations. Strategic application of herders are also able to provide short-term protection of sensitive areas thereby decreasing detrimental environmental impacts. Two surface collecting agents are currently listed and approved for potential use in the United States: Siltech OP-40 and ThickSlick 6535. Herder toxicity data is scarce and mostly focused on regulatory toxicity testing with standard species. It is urgent to assess potential adverse effects of herders on more geographically representative species to determine the level of ecological risks that may be associated with herding agent use. “We wanted to investigate the acute toxic effects of Siltech and ThickSlick herders on commercially important species in Atlantic Canada, including the vulnerable early life stages of green sea urchin, American lobster, Atlantic cod and lumpfish,” explained Dr. Davide Asnicar, Huntsman Marine Post-Doctoral Fellow and lead author on a publication in the international peer-reviewed journal Environmental Toxicology and Chemistry that describes the study results. All species specific toxicity tests were completed at The Huntsman Marine Science Centre laboratory located in St. Andrews, NB (Canada) under conditions that met the specific requirements for the species and life stages. Test media samples were shipped to the Danish Centre for Environment and Energy at Aarhus University (Roskilde, Denmark) for chemical analysis. “We have tremendous staff and facility capacity at Huntsman Marine to complete professional toxicology testing across a wide array of ocean species and often most vulnerable early life stages,” added Asnicar. All four test species have adult life stages that reside near or on the seabed well out of harms way from the effects of a surface oil spill or possible presence of chemical herders. However, these species also have early life stages (gametes, embryos and larvae) that develop in the water column where they are more likely to be impacted by an oil spill and ongoing mitigation operations when seasonally present. The four species also cover several animal groups and trophic levels with the early life stages being present across all seasons of the year. Green sea urchins reside on the ocean floor and are harvested in Atlantic Canada with commercial landings typically valued at more than $5 million annually. Sea urchin gametes are expressed into the water column where fertilization occurs when the seawater temperature is optimally about 8-12 ºC. A sea urchin fertilization test was used in this study to assess fertilization success in the presence of both herders at varying concentrations. American lobster forms the basis of a very important fishery throughout Atlantic Canada with landings expected to be over $2 billion each year. Female lobsters carry fertilized eggs on their abdomen for about a year with hatching in the Bay of Fundy region occurring during late-summer to mid-fall when seawater temperature is near its peak. “Huntsman Marine has developed numerous repeatable exposures involving all lobster life stages, with a frequently performed test focused on the newly hatched Stage I larvae that live in the upper water column where interaction with a surface oil spill is possible during those 3-4 months when larval lobsters are present,” explained Asnicar. Testing with Atlantic cod and lumpfish larvae is another Huntsman Marine specialty that is not readily performed by other toxicology labs globally. Both of these tests require maintenance of in house adults that become mature to spawn and provide access to gametes or fertilized eggs for incubation and hatching. The commercial value of Atlantic cod landings is presently a shadow of what it once was but still surpasses $20 million annually. Spawning occurs during winter and this requires exposure temperatures to be maintained at 3-7 ºC to provide realistic results. The lumpfish fishery is considerably lower in value but the species is receiving more recent attention due to its threatened status and consideration for listing under the Species at Risk Act in Canada. Lumpfish spawn in the April-May period and testing occurred at 12±2 ºC. The herder Siltech was found to be between 4 and 78 times more toxic than ThickSlick regardless of the test species or endpoint measured. The sea urchin fertilization test produced the most sensitive endpoint in the study with an effective concentration to cause an impact in 50% (EC50) of the fertilization success of 1.0 mg/L following a 20-minute exposure to Siltech. The least sensitive test to Siltech was from the lumpfish exposure for 3 hr with the lethal concentration to cause mortality in 50% (LC50) of the exposed larvae to be 13.4 mg/L. Siltech caused significantly higher mortality in Stage I lobsters than ThickSlick, however, all larvae that survived were able to molt from Stage I to Stage II lobsters during the exposure trials. Exposures to the herder ThickSlick using the same early life stages provided very different sensitivity results. The hatching success of 20-day-old cod embryos was the least sensitive to ThickSlick with an EC50 of 476.6 mg/L. The most sensitive endpoints were the survival of 24-hr-old cod embryos, with an LC50 of 8.6 mg/L at 48 hr and 7.6 mg/L at 72 hr, and the sea urchin fertilization 20-min EC50 of 8.8 mg/L. The choice of whether and which herder to use in the event of an oil spill will be based on what is approved by regulators, the type of oil spilled, and net environmental benefit analysis for the specific environmental sensitivity. “We are pleased to contribute necessary hazard data that regulators may use when choosing the best path forward to address a possible oil spill while providing the highest level of protection to the environment,” concluded Asnicar. The research publication was co-authored by researchers at Aarhus University (Roskilde, Denmark) and Fisheries & Ocean Canada. The study was funded by Fisheries & Ocean Canada through Canada’s Ocean Protection Plan, New Brunswick Innovation Foundation and The Huntsman Marine Science Centre.

Press Room Huntsman Marine research expand possible options for oil spill clean-up response in Atlantic Canadian waters St. Andrews, New Brunswick, Canada – February 18, 2026 Canada has vast ocean space with high levels of offshore oil production and transportation activities but few options to mitigate the impacts associated with an oil spill within our coastal waters. Surface collecting agents (also called herding agents or herders) may assist in removing spilled oil by controlling its spread across the water surface to facilitate mechanical removal or aid in situ burning operations. Strategic application of herders are also able to provide short-term protection of sensitive areas thereby decreasing detrimental environmental impacts. Two surface collecting agents are currently listed and approved for potential use in the United States: Siltech OP-40 and ThickSlick 6535. Herder toxicity data is scarce and mostly focused on regulatory toxicity testing with standard species. It is urgent to assess potential adverse effects of herders on more geographically representative species to determine the level of ecological risks that may be associated with herding agent use. “We wanted to investigate the acute toxic effects of Siltech and ThickSlick herders on commercially important species in Atlantic Canada, including the vulnerable early life stages of green sea urchin, American lobster, Atlantic cod and lumpfish,” explained Dr. Davide Asnicar, Huntsman Marine Post-Doctoral Fellow and lead author on a publication in the international peer-reviewed journal Environmental Toxicology and Chemistry that describes the study results. All species specific toxicity tests were completed at The Huntsman Marine Science Centre laboratory located in St. Andrews, NB (Canada) under conditions that met the specific requirements for the species and life stages. Test media samples were shipped to the Danish Centre for Environment and Energy at Aarhus University (Roskilde, Denmark) for chemical analysis. “We have tremendous staff and facility capacity at Huntsman Marine to complete professional toxicology testing across a wide array of ocean species and often most vulnerable early life stages,” added Asnicar. All four test species have adult life stages that reside near or on the seabed well out of harms way from the effects of a surface oil spill or possible presence of chemical herders. However, these species also have early life stages (gametes, embryos and larvae) that develop in the water column where they are more likely to be impacted by an oil spill and ongoing mitigation operations when seasonally present. The four species also cover several animal groups and trophic levels with the early life stages being present across all seasons of the year. Green sea urchins reside on the ocean floor and are harvested in Atlantic Canada with commercial landings typically valued at more than $5 million annually. Sea urchin gametes are expressed into the water column where fertilization occurs when the seawater temperature is optimally about 8-12 ºC. A sea urchin fertilization test was used in this study to assess fertilization success in the presence of both herders at varying concentrations. American lobster forms the basis of a very important fishery throughout Atlantic Canada with landings expected to be over $2 billion each year.

Press Room Harvest timing and processing duration affect Atlantic salmon fillet colour St. Andrews, New Brunswick, Canada – April 1, 2026 Atlantic salmon fillet colour can be influenced by diet and genetics while playing an important role in consumer purchasing decisions. The reddish colour of salmon fillets comes from the binding of naturally occurring unmetabolized carotenoid pigments, such as astaxanthin and canthaxanthin, to the muscle – which is the same process that gives the pink to reddish-orange feathers of a flamingo! Adding natural astaxanthin to the salmon diet is now a common practice but at considerable expense as it accounts for 5-10% of total feed cost. It is therefore important to understand the effect of fish and family genetics for those able to deposit and retain more of the pigmentation in their muscle to give favorable fillet colour. Earlier published data from The Huntsman Marine Science Centre (St. Andrews, NB) reported that fillet colour was a highly heritable trait amongst salmon families. However, colour intensity and variability are known to be influenced by many factors. Breeding programs rely on accurate measurements when describing a specific trait, such as measured during commercial harvest evaluations, to make informed breeding decisions. Any effect of small time discrepancies over hours to days on muscle colour intensity has received limited research attention. However, these effects could impact the perceived quality of fish and may alter accurate estimation of breeding values for selection. “We had a unique opportunity to collect detailed data on thousands of individual fish over many years of production during commercial scale harvest evaluations,” explained Dr. Amber Garber, Huntsman Marine Research Scientist and anchor author of the recent publication in the international peer-reviewed journal Aquaculture. “Our detailed dataset gives us the ability to assess how quality traits, like fillet colour, are affected by harvesting and processing time to increase confidence in our selection decision making process.” Huntsman Marine researchers recently published results from 10,380 individual Atlantic salmon fillets that were collected over eight year classes from 2011 to 2019. All collected data was time stamped to evaluate the impact of harvest day, hour of the day, and processing duration from the time between entering the plant facility to assessing fillet colour. Fillet colour was assessed both visually by comparing it to a standard swatch called a SalmoFan and measuring the colour components of redness, yellowness and lightness using a Minolta Chroma Meter. Harvesting all fish from a sea cage may occur in two or three separate harvest events in order to adequately provide workers sufficient time to process fish. The environmental conditions and feeding regimen experienced by the salmon remaining within the cage may differ dramatically as the total harvest proceeds. Not being fed again before harvested or experiencing stress during previous removals of fish may also affect fillet quality and color once remaining fish are eventually harvested. The 2015 year class fish had the largest span of days between first and last harvest and also experienced the greatest effect of days for the harvest on colour with generally lighter fillets as days increased. “It is reasonable for about three days to pass for gutting, rigour mortis and then filleting harvested Atlantic salmon for fillet colour assessment to occur and ideally each fish would be processed in the same amount of time,” noted Garber. “Only our 2017 year class involved a single harvest day so that all plant activities were completed for the entire assessed group at the same time and, as expected, these salmon fillets were not influenced by time.” Some fish in the study were assessed for colour up to 46 h after these same measurements were completed for other fish. Generally, the data showed that longer times to complete the processing requirements resulted in fillets that were lighter in colour. Processors recognize that the way salmon are stored and filleted post-mortem may affect fillet colour and the data published here further confirms this notion. S almoFan scoring was the only colour measurement that was significantly affected by time of day with lower values assigned later in the day. All SalmoFan assessments were completed by the same individual but this is a subjective measurement and may be influenced by eye fatigue or general weariness as the evaluation day progresses. Correcting the SalmoFan scores to account for the hour of the day increased its correlation with Chroma Meter colour component measurements. All measured colour traits from each year class had moderate to high heritability ranging from 0.260 to 0.859 when days of harvest, duration of processing and hour of the day were not accounted for in the models. These heritability estimates increased to be within a range from 0.286 to 0.860 when these time components were included in the statistical model. Fillet lightness and SalmoFan values showed the largest changes in most year classes when timing effects were included in the analysis. It is important to include a time stamp when collecting data as without these considerations certain fish may be erroneously perceived to have a higher value relative to other individuals thereby skewing overall trait heritability and selection. Completing full harvest evaluations in as few days possible is important to ensure the most appropriate comparison of results across individual fish and families as well as amongst year classes in a commercial breeding program. The published results may also have broad applicability to general product quality and marketing of farmed Atlantic salmon. “Our published results demonstrate the effect of days of harvest, duration of processing, and hour of the day on heritability and fillet colour Estimated Breeding Values,” concluded Garber. “It is essential that we time stamp data collection when evaluating colour traits, and possibly other quality traits, to make unbiased breeding decisions and apply genomic selection analysis.” The publication was co-authored by researchers at Mowi Genetics AS (Bergen, Norway). The study was funded by the Atlantic Canada Opportunities Agency (ACOA) Atlantic Innovation Fund, New Brunswick Innovation Foundation (NBIF) Research Innovation Fund, Genome Canada & Genome Atlantic, and industry partners.
