Feed additives in aquaculture2017-12-14
Researchers of Nutrigenomics and Pathology Groups of Institute of Aquaculture Torre de la Sal, in collaboration with the companies NOREL and EVONIK, evaluated the potential benefits of two commercially available feed additives, one based on medium-chain fatty acids (MCFAs) from coconut oil and another a Bacillus-based probiotic (B. amyloliquefaciens CECT 5940), in gilthead sea bream, a marine farmed fish of high value for the Mediterranean aquaculture.
This study showed differential beneficial effects induced by these dietary supplements: MCFAs exhibited a great growth-promoting action while the Bacillus-based probiotic revealed promising effects on immune maintenance and disease resistance in a farmed fish.
The results have been published in the Open-access Journal PeerJ (enlace).

The clock of gilthead sea bream larvae2017-10-18
- A coordinated research by two institutes from CSIC-Spain, the Instituto de Ciencias Marinas de Andalucía (ICMAN) and the Institute of Aquaculture Torre de la Sal (IATS), depicted the daily rhythms of whole gilthead sea bream larvae and provides tools to refine culture practices and establish novel quality criteria/certificate for larvae
- Fast growth of gilthead sea bream larvae occurs greatly because of a high synchronization among several biological processes through the day
The study, published in the journal Scientific Reports (https://www.nature.com/articles/s41598-017-13514-w), was founded by the projects RIDIGEST (MINECO-AGL2011-23722) and ARRAINA (7FP KBBE-2011-288925 project No. 288925).

TNA STAY AQUAEXCEL20202017-04-10
The PhD Student Mar Marcos from Galway-Mayo Institute of Technology (Ireland) has concluded a four-weeks stay in the Institute of Aquaculture Torre de la Sal (IATS-CSIC, Castellón, Spain) within the transnational access entitled “Study of genes involved in the epithelial and mucous cell hyperplasia occurring in gills of farmed Atlantic salmon during amoebic gill disease –AGDBIOMAR” financed by the European Project AQUAEXCEL2020.
The study was conducted in collaboration with researchers of Nutrigenomics and Pathology Groups of IATS
We hope her stay in our Group has been satisfactory.
The first follow-up meeting of PROGENSA III Project (2016-2018), organized by APROMAR/REMA, was held at the Polytechnic University of Valencia (April 5, 2017).
The Project, coordinated by Universidad de Las Palmas de Gran Canaria (ULPGC), is financed by the National Aquaculture Plans of the Ministry of Agriculture, Food and Environment with the help of the European Maritime and Fisheries Fund.
The meeting was attended by researchers from the ULPGC, IFAPA, IEO-Murcia, UPC and IATS-CSIC, together with representatives of sector companies of Cantabria, Andalusia, Murcia, Valencia, Baleares and Canarias, that discussed the work plan and expected results of the gilthead sea bream genetic selection program that began in 2009 and has its continuity in PROGENSA III.
The IATS-CSIC Research Group participates in this Project with researchers from the Nutrigenomics and Fish Pathology Groups who will evaluate, with families selected by ULPGC and IFAPA, the effects of nutrition x genome interaction on growth, conversion efficiency and disease resistance in a model of parasitic enteritis with E. leei.
The larval cultures for the studies of nutrition x genome interaction at IATS-CSIC are being carried out in the facilities of the IEO of Murcia. The culture start at IATS is planned for June-July 2017.
Serum metabolome of gilthead sea bream2017-02-05
Researchers of Nutrigenomics and Fish Growth Endocrinology Group of IATS in collaboration with the Institute of Waters and Pesticides of the University Jaume I of Castellón analysed by high resolution liquid chromatography and mass spectrometry the serum metabolome of farmed gilthead sea bream.
More than 15,000 m/z ions were identified in the serum of gilthead sea bream. Among them, 850 features were discriminant of fed and short-term fasted fish, helping to identify sensitive and robust metabolite markers of malnutrition in farmed fish.
Further studies are underway to determine the potential of this powerful methodological approach, alone or in combination with other omics approaches, for the discovery and validation of new biomarkers of nutritional status in a wide-range of physiological conditions arising with the advent of feed additives and new fish feed formulations.
The results have been published in the Open-access Journal PeerJ. Read more....

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 (firstname.lastname@example.org).

End of stay at IATS for two ERASMUS students2014-09-30
We say goodbye to students Debora D'Angelo and Alessandro de Ambrosi from the Università degli Studi dell'Insubria (Italy), after their five months (May-September) ERASMUS stay at IATS facilities and laboratories. Debora´s work has been focused on the molecular and functional characterization of the gilthead sea bream intestinal mucus proteome, Alessandro´s in the molecular identity and expression of metabolic sensors and growth factors in gilthead sea bream. Their stays have been mastered by Dr. Ariadna Sitjà and Prof. Jaume Pérez, respectively. We hope they profited and enjoyed their stays with us as much as we did from their company and assistance. We wish them the best in their future careers. Arrivederci!
AQUAEXCEL transnational access at IATS by a CIIMAR PhD student2014-08-01
PhD student Rita Azeredo, from CIIMAR (Portugal) has concluded a six-week stay in IATS experimental facilities and laboratories, within two transnational accesses (experimental-TNA-EXP- and analytical-TNA-ANA-, respectively) financed by European Project AQUAEXCEL. During her stay, supervised by Dr. Ariadna Sitjà (TNA-EXP) and Professor Jaume Pérez (TNA-ANA), she has conducted studies on the effect of dietary L-arginine supplementation on the immune response, the gene expression profile of the immune system and disease resistance of European sea bass.
