The research group of the University of Murcia (UMU) Inespecific Immunity System of Teleost Fish, manages to introduce the results of its basic research in the business sector and in society.

This transfer has materialized recently with the granting of a patent, born of the work carried out together with researchers of the UPCT (promoters of the action), and which aims to reduce the stress of aquaculture fish to improve their quality when we consume them and lengthen its useful life.

In addition, these advances have been awarded the Jacumar Prize for research in Aquaculture, granted by the Ministry of Agriculture and Fisheries, Food and Environment.

A fact that for the UMU professor Alfonsa García Ayala supposes a tremendous satisfaction, since after so many years of basic research they have finally found a way to apply their results in companies, "contributing to change their protocols of action".

Thanks to the reception of this project the researchers have obtained funding for a European project that will allow to continue working with the gilthead seabream, and expand the samples to species with which they had not previously worked such as sea bass, trout or salmon.

New technology applied to murcian aquaculture

Traditionally, aquaculture fish, on the high seas, were taken to hypothermia to be frozen, whose consequences were translated into an agonizing death and a greater appearance of rigor mortis or post mortem rigidity.

In this project, entitled "Stunning and slaughter of aquaculture fish with nanoencapsulated clove essential oil embedded in ice crystals decreases animal suffering and improves the quality and shelf life of chilled fish", a new form of slaughter has been developed of aquaculture fish that decreases the agony of the animal, in this case of the gilthead bream, positively influencing both the quality of the fillets extracted from the fish and the decrease in the amount of microbiological load of the fish, allowing to double the shelf life of these fillets from 12-14 days to 28 days.

This initiative carried out by members of the two public universities of the Region of Murcia has been carried out within the framework of an R & D Project funded by the Center for Industrial Technological Development (CDTI) and the European Regional Development Fund .
