Serum metabolome of gilthead sea bream

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....
