PhD student Ibon García-Gallego from CCMAR (Portugal) is visiting IATS infrastructure through the AQUAEXCEL3.0 Transnational Acess (TNA) entitled FISH+ (Enhanching fish robustness through dietary functional additives). This TNA supervised by Nutrigroup Prof. Jaume Pérez-Sánchez. The TNA will analyze in the upcoming weeks the gut microbiota communities of samples from gilthead sea bream juveniles fed diets enriched with selected addtivies (thymol, butirate, taurine), in order to assess the impact of such additives on the enhancement of intestinal health of cultured fish.
The 2023 Stanford Ranking has recognized two IATS researchers (Jaume Pérez-Sánchez and Ariadna Sitjà-Bobadilla) among the most influential worldwide for their achievements throughout their research career. In addition, the Stanford list recognizes a third IATS researcher (Óscar Monroig) for his career over the last year.
Congratulations on this important achievement!

The Final Conference of AquaIMPACT Project was held at Vienna on September 18th as an open conference in the framework of the EAS 2023. It was a successful event, with more of 110 people in the audience. IATS-CSIC Nutrigenomic group participated with two presentations. One highlighted the importance of microbiota gut resilience and functional plasticity as traits to be considered for future selective fish breeding and nutritional innovation programs. The other one linked nutritional programming, the use of feed additives and gut micriobiota in two gilthead sea bream populations, showing as an outcome that the nutritional improvement of farmed sea bream is largely dependent of both the metagenome and host genome according to the Hologenome theory of evolution.
A short AquaIMPACT vídeo with the main relevant messages of industry is available.
Nutrigroup PhD student Ricardo Domingo-Bretón is one of the three nominees to the Student Spotlight Award granted by the EAS at the upcoming Aquaculture Europe 23 Congress (September 18-21, Vienna), with the work entitled “Gilthead sea bream microbiota shifts associated with thermal stress and dietary intervention during a record heat summer“.
This work resulted by collaboration with Nukamel company through the AQUAEXCEL3.0 Transnational Access EMULSAQUA2, with additional funding from National THINKINAZUL project. The combined effect of diet fat level and emulsifier supplementation (Volamel Aqua) was tested in juvenile gilthead sea bream during the extremely hot summer of 2022 at the Spanish Mediterranean coast. Gut microbiota was revealed as a strong biomarker of heat stress, and the feed additive turned down the microbiota dysbiosis and mimicked the microbiota changes associated to low energy diets. A nice piece of work that merited his nomination. Best of lucks for Ricardo.
PhD student Ricardo Matias, from CIIMAR (Portugal) has completed an experimental AQUAEXCEL3.0 Transnational Access (TNA) stay with IATS-Nutrigroup.
The RAYON2BASS TNA consisted in a feeding trial aimed to assess the impact of cellulose-based microfibres on sea bass growth parameters and nutrient utilisation.
The “Training course on Nutritional Innovations for Selected Aquaculture Fish” took place the 28-29 June in the Wageningen Campus, in the Netherlands. This was one of the two courses that AquaIMPACT project organized to train aquaculture professionals and students with the latest concepts about fish genomic selection and nutrition.
A total of 24 students from 9 nationalities attended the course, with lecturers belonging to research (INRAE, University of Las Palmas de Gran Canaria, University of Stirling, CSIC, University of Insubria) or aquaculture-related (Skretting Aquaculture Research Centre) institutions. The organization of the activity was promoted by the University of Las Palmas de Gran Canaria.
The IATS representation in this course was composed by Álvaro Belenguer and Fernando Naya-Català, from the Nutrigenomics Group. Álvaro showed recent research undergone by the group on sea bream nutritional programming, and explained the transcriptomics and epigenomic links after the implementation of this technique. Fernando explained the importance of the gut microbiota as a key factor to explain the relationship between fish breeding and nutritional interventions, and how this community and the host gut transcriptome can be modulated in sea bream by feed functional additives.
The Nutrigroup PhD student Fernando Naya-Català just came back from a 3-months stay at the Center for Integrative Genetics (CIGENE-NMBU), in Aas, Norway. Nando was trained in the use of the PromethION platform for the generation of whole genome sequencing data and the detection of DNA methylation patterns in the sea bream genome, under the supervision of Profs. Matthew Peter Kent and Sigbjørn Lien, and Drs. Mariann Arnyasi and Arturo Vera Ponce de León.
This stay, co-financed by the EMBO and iMOVE short-term mobility fellowships, will help Nutrigroup to gain expertise in the working and performance of third-generation sequencing systems for epigenomics aproaches, promoting the knowledge advance in this field.
Beatriz Soriano successfully presented her doctoral thesis at Institute for Integrative Systems Biology (I2SysBio, UV-CSIC) on june 15th.
Her work, entitled “Bioinformatics solutions for the analysis of omics data, knowledge discovery and genetic diagnosis in Sparus aurata and other biological organisms” was co-directed by Carlos Llorens (Biotechvana), Jaume Pérez (IATS Nutrigenomics Group) and Vicente Arnau (I2SysBio). It was financed by the Ministry of Science and Innovation through a grant for contracts for the training of doctors in companies (Doctorados Industriales).
The Thesis defense was awarded with the highest distinction. Congratulations to Beatriz for her excellent work.
Dr. Massimiliano Babbucci, from the University of Padua (UNIPD, Italy), has just started a 3-week stay at the Biology and Culture of Molluscs team of the IATS-CSIC (BICUMOL). Dr. Babbucci will work in the VENUSREAR project funded by the AQUAEXCEL3 collaborative European Network of aquaculture facilities. The goal of this project is to attempt rearing the striped venus clam (Chamelea gallina) in captivity. VENUSREAR ‘s principal investigator is Dr. Chiara Papetti, who accompanied Dr. Babbucci in his first day at IATS. Fisheries of the striped venus clam, an essentially Mediterranean species, have declined to near extinction in many fishing grounds. Development of captive breeding in this species could facilitate restocking and aquaculture. The same species is the focus of the project RECLAM, carried out in collaboration with the Universidad Politécnica de Valencia (Spain) with funding from de Spanish government (PRTR plan), the government of the region of Valencia (Spain) and the EU. Emmanuel O. Adesuyi, a student in the Marine Biology Master program at UNIPD, has joined this project to carry out his master’s thesis, funded by the Erasmus+ program. In the photo, from left to right, David Cordero (IATS technician), Dr. Babbucci, Emmanuel Adesuyi , Dr. Papetti and Dr. Carlos Saavedra (BICUMOL principal investigator).
Dutch student Justin Bleeker is completing a 4-month training stay, between February and June, through the Erasmus+ programme at the Nutrigenomics and Fish Growth Endocrinology group. Justin comes from the Noorderpoort college in Groningen, Netherlands, where he is being trained to become a laboratory technician. On the first of June of 2023 his teachers Kim Fränkel, Renella Herder and Harold C. Tammeling visited the IATS, as Justin’s supervisors, to evaluate his work in our Center.
