Ricardo Domingo-Bretón nominated to Student Spotlight Award of Aquaculture Europe 23 Congress2023-09-15
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.

XIII Workshop of Spanish Society of Microbiome, Probiotics and Prebiotics2022-06-10
Prof. Jaume Pérez-Sánchez was invited by the Spanish Society of Microbiome, Probiotics and Prebiotics to give a conference at their XIII Workshop, held in Valencia (June 7-9). His talk was focused on the latest group results in National and European Projects, regarding the interplay of mucosal microbiome composition of farmed fish with culture conditions, nutrition and genetic background. The presentation is available for download here.
6th International Symposium on Genomics in Aquaculture2022-06-08
Researchers and students of Nutrigenomics and Fish Pathology groups of IATS have attended the 6th International Symposium on Genomics in Aquaculture, held in Granada (May 4-6). They have participated in three oral communications.
Beatriz Soriano presented SAMBA (Scanning Aquaculture Microbiome via Bayesian Approach), an application based on Bayesian networks intended to predict changes in the composition and function of mucosal microbiome in farmed fish, correlating microbial architectures with a number of biotic and abiotic factors. SAMBA also permits to interrogate the model to identify which experimental conditions are optimal for obtaining a given pan-microbiome and associated metagenome. This application will be implemented to be accessible as a web server at this site.
Fernando Naya-Català talked about the interaction of the genetic background and dietary intervention through feed additives, driving reshaping of gut microbiome in gilthead sea bream. Experimental diets oil-coated with organic acids, Bacillus-species probiotics or natural plant extracts were tested in fish selected and unselected for growth. It was demonstrated that genetics and diet interaction on gut microbiota was specific for each additive, being gut microbiota less variable in selected fish.
Socorro Toxqui Rodríguez showed the validation of Oxford Nanopore minION technology as a fast and low-cost tool for the profiling of mucosal sea bream microbiota. This technology was compared with 16S amplicon data generated by other established techniques such as MiSeq and PacBio. Her presented results provided precise insights into the advantages and disadvantages of this specific sequencing platform, and their suitability depending on the experimental approach, expected output, and cost and time constraints of a given experiment.
Gut microbiota and host transcriptome interaction for adaptation of fish to fish meal-free diets2022-05-27
Researchers of IATS Nutrigenomics and Fish Pathology groups, in collaboration with enterprises Sparos (Portugal) and Adisseo (Portugal) have recently reported in Aquaculture the notable results achieved in terms of growth and sanitary status of gilthead sea bream fed fish meal devoid diets, based on principles of circularity and resource utilization in the framework of EU GAIN project.
The new diet formulation was able to support optimal growth, and the suspceptibility to experimental infection with the intestinal myxozoan parasite Enteromyxum leei was not altered by diet. The fish adapted to this new diet formulation through changes in gene expression and gut bacterial composition. Moreover, it was shown that intestinal microbiota and host gene expression were correlated, evidencing that they can interact not only locally but also at a systemic level.
This work remarks the contribution of GAIN-derived feed formulations to sustainable aquaculture. The aquaculture-related site mispeces.com has published a press note (in spanish).

Participation at GAIN Workshop “Novel aquafeeds”2021-09-23
Researchers of IATS Nutrigroup and Fish pathology group have participated in the “Novel aquafeeds” Workshop (21-22 September, online), organized by GAIN H2020 project with support from H2020 projects PerformFISH, AquaIMPACT, MEDAID, AQUAVITAE and NewTechAqua, as well as Italian project SUSHIN. The workshop was intended to present and discuss novel fish feeds that support eco-intensification of the European aquaculture industry.
Prof Jaume Pérez from IATS Nutrigroup shared with the audience the results of feeding trials in gilthead sea bream with sustainable GAIN feed formulations in the “Alternative fish feed formulation” session. Transcriptome and microbiome data highlighted how these diets, mainly those based in processed animal protein, supported optimum growth and immune response, contributing to sustainable aquaculture. Workshop session “Novel tools to assess feed performance” had two IATS contributions: Dr Carla Piazzon from Fish Pathology group talked about fish gut microbiome analysis, how it is affected by genetic background, diet, age or season, and the occurrence of a plastic microbiota adaptable to diet changes as a result of fish selection for heritable growth; and Jaume Pérez defined the potential of AEFishBIT sensor device for fish behaviour monitoring and its contribution to refine nutrient requirements and feeding schedules for more robust and sustainable fish.
Nutrigroup at the 13 AIEC Congress2021-09-17

IATS Nutrigroup has participated with two oral communications. Fernando Naya-Català highlighted the developmental and hypoxic Gh/Igf system programming in gilthead sea bream. And Paul Holhorea showed how the sex population ratio in cultured gilthead sea bream can be regulated by the nutritional and genetic background, and serves as a welfare indicator alerting of disturbance conditions altering reproductive performance and perhaps overall growth and offspring quality. Group works were funded supported by National (Bream-AquaINTECH) and European (PerformFISH) projects.
Next AIEC meeting will be, hopefully in person, in Bilbao in September 2023.
Hypoxia and exercise performance in fish2021-05-19
Researchers from the Nutrigroup of IATS-CSIC have targeted the mild-hypoxia driving force for metabolic and muscle transcriptional reprogramming of gilthead sea bream juveniles, focusing on blood metabolic landmarks and muscle transcriptomics before and after exhaustive exercise. These results after mild-hypoxia conditioning highlighted an increased contribution of lipid metabolism to whole energy supply to preserve the aerobic energy production, a better swimming performance regardless of changes in feed intake, as well as reduced protein turnover and improved anaerobic fitness with the restoration of normoxia.
The results of this work, funded by National (BreamAquaINTECH; RTI2018–094128-B-I00) and European AQUAEXCEL2020 (Aquaculture infrastructures for excellence in European fish research towards 2020; 652831) Projects, have been published in the special issue Transcriptome and Genome Analyses Applied to Aquaculture Research of the open-access Journal Biology (link).

Insect larvae meal as a sustainable feed ingredient in aquaculture 2021-04-15
A recent collaboration between IATS Nutrigenomics group and CIIMAR from Porto University (Portugal) has highlighted the feasibility of high replacement of fish meal in aquaculture diets with insect-derived meal.
The effect of fish meal replacement by defatted mealworm (Tenebrio molitor) larvae meal in European sea bass aquafeeds was tested, evidencing that it was possible to replace up to 80% of fish meal by insect meal without impairing growth performance, nutrients digestibility and fillet quality.
These results are of special importance for the growing need of environmentally sustainable alternatives to fish meal in aquaculture.
The work has been partly funded by a transnational access (TNA) of H2020 project AQUAEXCEL2020 at IATS infrastructures. It was selected as a relevant output in the Info Day of EATiP at Aquaculture Europe 2019 in Berlin, and it has been recently published in the Open Access journal Frontiers in Physiology.

Serum metabolome markers of intestinal parasitic infection in gilthead sea bream2019-11-21
Researchers of IATS-CSIC Nutrigenomics group and Fish Pathology group, in collaboration with Universitat Jaume I, Universidad de Cadiz and Portuguese Algarve University, have recently reported the effect of the myxozoan parasite Enteromyxum leei on gilthead sea bream gut integrity and permeability.
The response to an experimental infection with E. leei was studied by means of immunocytochemistry, electrophysiology, metabolomics and intestinal permeability analysis techniques.
This work provides the first functional evidence of the degradation of intestinal integrity caused by this parasite. Differences in serum metabolome in infected fish has highlighted valuable information about markers of parasite infection. In this regard, serum levels of creatine and inosine become excellent markers for discriminating infected and non-infected fish.
This work, which constitutes and important advance on the physiopathology of enteritis, and opens the possibility to new palliative procedures, has been funded by National and European (AQUAEXCEL2020 and ParaFishControl) Projects, and has been recently published in the Open Access journal Parasites & Vectors.
Photomicrographs of gilthead sea bream sections of anterior intestine immunolabelled (brownish colour) with antibodies against claudin 3 (CLDN3), tight junction protein 1 (TJP1) and E-cadherin (CDH1). For each intestinal segment, the upper panel corresponds to control healthy fish and the lower panel to Enteromyxum leei-parasitized fish. Arrowheads point to some labelled parasitic stages, and arrows to some of the positive immunostaining of control fish.
Protective effects of seaweed supplementation in European sea bass diets2019-11-14

Project Catalogues are available for download:
Defatted yellow mealworm larvae meal
Early life management protocol
PhD student Ana Basto (CIIMAR) discussed outcomes of research from IATS-EXP TNA project INSECTFISH, focused on European sea bass feeding with mealworm Tenebrio molitor meal. The principal aim of this research was to assess the use of large quantities of insects as protein sources to replace fishmeal in diets for sea bass, and to examine possible effects on their growth and welfare. Dr. Josep Calduch-Giner presented a protocol for early life management for optimal fish performance, highlighting surprising findings in relation to low O2 (hypoxic) conditions at early life stages of gilthead sea bream and its impact later in life. In terms of fish disease, Dr. Carla Piazzon presented on gene expression analysis of Atlantic salmon gills, derived from IATS-ANA TNA project AGDBIOMAR, and how it reveals certain key molecules during amoebic gill disease, one of the main health challenges for the marine Atlantic salmon industry worldwide. It is expected that the findings could contribute to a more timely and accurate detection of the disease which will prevent stock losses and improve fish welfare. Results of this work were recently published in an Open Access publication.
In addition to the knowledge outputs, Professor Jaume Pérez-Sánchez, as AQUAEXCEL2020 WP8 leader, presented the AEFishBIT device to the audience, with a video and an exposition of latest results and applications of this patented biosensor in sea bream and sea bass. This tiny device is designed to be attached to the operculum of farmed fish for individual monitoring of their metabolic traits. The newly patented tool is the result of collaboration amongst biologists, engineers and bioinformaticians from two AQUAEXCEL2020 institutes.
After the event presentations, interactive polls with audience overall revealed a major interest in most of the presented outputs. The next and final AQUAEXCEL2020 industry brokerage event will be held at next year’s Aquaculture Europe 2020 event in Cork (Ireland), presenting the latest high-potential industry-relevant outputs that will be resulting from the final year of the project.
Nutrigroup at XII AIEC Congress: fish biosensing2019-10-01
The interest in the patented AE-FishBIT device continues to grow. Nutrigroup member Kike Rosell-Moll presented a poster in the XII Congress of Asociación Ibérica de Endocrinología Comparada (AIEC, 26-28 September, Faro, Portugal). After the first published work presenting this promising biosensing device for tracking fish behavior, this poster assessed the lack of negative impact of AE-FishBIT attachment to fish operculum, as well as analyzed the measured device response in free-swimming fish against changing biotic (biological age) and abiotic (oxygen level, available tank space, parasitic infection) factors. Congratulations to Kike for this work, that is available online, has been awarded with one Best Poster prize in this Congress.
Nutrigroup at XII AIEC Congress: gilthead sea bream genome2019-10-01
The XII Congress of Asociación Ibérica de Endocrinología Comparada (AIEC), held 26-28 September at Faro, Portugal, has been quite productive and successful for Nutrigroup rookies. Fernando Naya-Català was honored with one prize for Best Oral Communication for the presentation about the sequencing of the genome of gilthead sea bream and the adaptation insights derived of the large genome size and the high level of gene duplications observed in this plastic species.
This prized work has been recently uploaded to bioRxiv and it is expected to be published soon in a ranked scientific journal.
Sea bream resilience to moderate hypoxia and high stocking density2019-08-02
Researchers of IATS Nutrigenomics and Fish Growth Endocrinology Group have assessed the re-adjustment of tissue metabolic and transcriptomic profile of gilthead sea bream exposed to two different levels of oxygen concentration (normoxia and moderate hypoxia) and stocking densities (9.5 and 19 kg/m3).
Integrated data on blood haematology, biochemistry and hormonal profiling evidenced that reduced oxygen availability induced a hypo-metabolic state with lower feed intake and growth rates, although it was accompanied by a more efficient energy metabolism. Transcriptional results also supported these findings, and the tissue-specific orchestration of stress response reflected the different metabolic capacities of targeted tissues (liver ≥ heart > skeletal muscle > blood). Knowledge on this global but also differential tissue-orchestration to reach the homeostatic load of fish is of special importance to warrant fish welfare during intensive farming conditions.
The results have been published in the Open-access Journal Frontiers in Physiology (link).

A new tool for reliable metabolic phenotyping of fish2018-06-05
Researchers from the Nutrigenomics and Fish Growth Endocrinology Group of the Institute of Aquaculture Torre de la Sal have evaluated the value of sirtuins (SIRTs), a family of proteins considered as master regulators of metabolism, for the metabolic phenotyping of the gilthead sea bream, a marine fish of high value for the Mediterranean aquaculture. The study showed that SIRTs may play different roles in the regulation of metabolism, inflammatory tone and growth in farmed fish. Also, the study revealed that the SIRTs profile allows the identification of individuals with metabolic features that lead to efficient and lean fish. This may be particularly useful in breeding programs for this species, by assisting gross measurements of visceral fat that are currently used to indirectly select efficient fish. The study has been published in Frontiers in Physiology and was founded by the projects MI2-Fish and PROMETEO FASE II, with additional support from PerformFISH-H2020.

New Publication: UNDERSTANDING BIOMARKERS IN FISH NUTRITION2016-12-12
Press release: December 2016
The EU-funded ARRAINA (Advanced Research Initiatives for Nutrition & Aquaculture) project has published a new resource for aquaculture feed producers, entitled “Understanding Biomarkers in Fish Nutrition”. The technical content is prepared by CSIC with contributions from other ARRAINA partners (NIFES, INRA, NARIC, ULPGC, USI, CCMAR).
The objective of this booklet is to provide a reliable set of biomarkers and associated methodologies to assess the nutritionally mediated effects on growth performance, metabolic homeostasis, stress responsiveness and health condition of fish which are fed new diet formulations from early life stages to completion of production cycle and sexual maturation. Of particular value are predictive and non-invasive biomarkers available at a relatively low cost, although the combination of conventional and omics approaches is emerging as a user-friendly option.
This booklet is specifically aimed at scientists and feed producers, but it also targets other industrial segments (e.g. fish farmers, feed additives companies, retailers) and individuals interested in gaining further knowledge of the physiological consequences of the raw materials that are currently used in the feeds of farmed fish. The species focussed on by the ARRAINA project are: Atlantic salmon, rainbow trout, common carp, European sea bass and gilthead sea bream.
This booklet is the final in a series of three technical booklets on the nutrition and feeding of fish farmed in Europe, and has been produced under the framework of the European Union FP7 funded ARRAINA project. The aim is to make these booklets widely available both to targeted stakeholders and society in general, in order to raise awareness of the science-based knowledge supporting the development of high quality, safe, and environmentally sustainable aquaculture feeds.
The first two ARRAINA technical booklets were focused on feed ingredients and nutrient requirements, and are available at www.aquatt.ie and can also be requested from the dissemination task leader Cliona Ní Cheallacháin, AquaTT (cliona@aquatt.ie).
