Congratulations to my friend and colleague, Niklas Warwas, PhD in our group, with his first publication ‘Marine yeast (Candida sake) cultured on herring brine side streams is a promising feed ingredient and omega-3 source for rainbow trout (Oncorhynchus mykiss)‘ that just got accepted in Aquaculture.
The overall aim of Niklas project is to look for sustainable protein sources to replace fisheal in fish feed. In this study, we investigated different inclusion rates of marine yeast as potential replacement for fishmeal, and we also investigated the potential of this ingredient as an immunostimulant. This is the first publication of many that we will have in common this year, as Niklas is defending his thesis at the end of the year, in which he has conducted no less than five feeding trials. Stay tuned for more publications on alternative ingredients as fishmeal replacement in 2023 (Picture from AES 2019).

I am very happy to announce the publication of our second research article from our MARTINIS project: ‘Candidatus Scalindua, a Biological Solution to Treat Saline Recirculating Aquaculture System Wastewater‘, where we slowly adaptedthe marine anammox species Candidatus Scalindua to the wastewater of a recirculating aquaculture system (RAS). It is the follow-up study of our first project where we exposed this bacteria suddendly to RAS waster, and noticed a diminution in the nitrogen removal rate, but no changes in bacterial community composition. In this follow-up study, we have shown that by gradually exposing this bacteria to RAS wastewater, we could maintain a good removal rate. In addition, we have shown that, unlike for freshwater anammox straings, trace element supplementation is not necessary for the normal functioning of marine anammox strains.
This article is part of the Special issue from Processes, ‘Wastewater and Waste Treatment: Overview, Challenges and Current Trends (Volume II)‘. I would like to thank all of our collaborators, sponsors, and the editors & reviewers from this special issue.

I am happy to participate in master project of our MARBIO-student Chiara Fasoli, within the SWEMARC-SMAK project, led by together with Snuttan Sundell and Carl-Johan Skogh. This project is aiming at communicating and integrating the results of SWEMARC’s research into everyday life, in order to create a greater understanding of the necessity of sustainable aquaculture in a future sustainable production of nutritious food. In this particular project, Chiara is in charge of setting up an aquaponic system with 8 graders at local school (Fridaskolan), and develop a protocol for teachers who wish to set up a similar system. I am helping out with the building of the system and we welcomed ca 70. students at zoologen at the beginning of February to show them our research facilities and our aquariums, and to talk about our research on multitrophic systems.

New project grant:
– I am very grateful to VINNOVA and Region Västra Götaland for funding our HIFAI project, a continuation of our previous Strategic innovation program for process industrial IT and automation – PiiA. We aim atidentifying how AI and new technologies can be further developed to enable a more ecologically and economically sustainable production of fish and seafood in land-based facilities (3,300,000 SEK). This project is a collaboration between our industrial partners (Smögenlax, Gårdfisk), the University of Gothenburg, Innovatum and the Swedish Environmental Research Institute (IVL), coordinated by my colleagues and main applicants Jacob Andrén and Torbjörn Johansson (IVL).

I am very happy to be back in Japan after more than two years. After visiting Hiroshima University and my collaborator and friend, Prof. Tomonori Kindaichi, I had the honored to meet his Excellency, Pereric Högbergto at the reception of the INTSAM funded project delegation at the Swedish embassy in Tokyo (13/11), and to represent GU and SWEMARC at the Research and Innovation week at Kyushu University (15-18/11). During this week, together with my colleague and friend Federico Micolucci, we presented the advances of our MARTINIS project during the Sustainability session. In addition, I had the pleasure to be selected to part of the discussion panel on Research and Ethics, where I discussed the topic of animal testing. It was a pleasure to meet again face to face and initiate with many researchers from different universities and disciplines in both countries. I am looking forward for follow-up discussions and potential collaborations. I would like to thank the Kyushu university staff for organizing this meeting and our generous sponsors for this trip INSTAM, VINNOVA and STINT.
New article accepted for publication, ‘Pain Recognition in Fish’, the first article published together with my friend and colleague Dr. Lynne Sneddon (main author). This article will be part of the special issue ‘‘Pain Management’ of the journal Veterinary Clinics of North America: Exotic Animal Practice, edited by David Sanchez-Migallon Guzman and to be published in January 2023.

June-July 2022
Presenting at the 14th edition of the ICBF 2022 in Montpellier (28/6-1/7), the results of the experiment led by my PhD colleague, Niklas Warwas, on the valorization of aquaculture and fisheries side-streams in order to find new sustainable alternatives to fish meal oils in aquaculture feed. The FEL group was well represented with presentations from my colleagues Niklas Warwas and James Hinchcliffe, and a poster from Ida Héden. The first international conference in over two years, it was nice to see old colleagues and friends from the fish world.
New article accepted for publication in Evolutionary applications: ‘Invader at the edge – genomic origins and physiological differences of round gobies across a steep urban salinity gradient’.
This work is a collaborative project with my colleagues from the University of Gothenburg, led by Dr leon Green. In this study, we investigated the physiological capacity of the invasive round goby (Neogobius melanostomus) to acclimatize to environments with different salinities. For this purpose, we used 12 937 SNPs to identify the genetic origin and diversity of three sites along the salinity gradient and round goby from western, central and northern Baltic Sea, as well as north European rivers. Fish from two sites from the extreme ends of the gradient were further acclimated to freshwater and seawater, and tested for respiratory and osmoregulatory physiology. Our results show genotypic and phenotypic differences over short spatial scales across this steep salinity gradient. These patterns of the physiologically robust round goby are likely driven by multiple introductions into the high salinity site, and a process of sorting, likely based on behaviour or selection, along the gradient. The article is in press and can be found here.
New project grants: I am very grateful to the Helge Axelsson foundation (30,000 SEK) who renewed its trust in me, and the J. Gust. The Richert foundation & SWECO (100,000 SEK) for awarding me two new grants to continue my research on alternative feed ingredients for aquaculture to be used in a feeding trial planned in the fall, stay tuned!)
Launch of a new journal: Frontiers in aquaculture, where I have been invited to be a review editor for the section Production biology. Don’t hesitate to submit your abstract to this section before August 31th.
May 2022
New article accepted for publication in Biology: ‘Low Holding Densities Increase Stress Response and Aggression in Zebrafish’.
This work is a collaborative project with my colleagues from the University of Gothenburg. In this study, we investigated the optimal housing densities of zebrafish in laboratory conditions, in order to better understand how holding density affects zebrafish behaviour and physiology. For this purpose, we evaluated the welfare of zebrafish housed at different densities (1 to 16 fish/L of water), over a period of 9 weeks. We observed that fish housed at the lowest density (1 fish/L) showed higher levels of aggression, spent more time in the top zone of the tank, and secreted more of the stress hormone cortisol in the water. Our data indicate that zebrafish should not be kept at densities of 1 fish/L, or lower, to ensure good welfare of the animals. We believe that these findings are important and will help to refine housing protocols for zebrafish.
This study was the master project of Mica, under the supervision of Petronella Kettunen. Since then, Mica has joined our group as a new PhD from the Blue food project (https://www.bluefood.se/), and we are now collaborating on new projects aiming at developing inland IMTA systems. Stay tuned for updates on our project. In the meanwhile, you can find our article here.
