The Oceanographic Centre in Murcia, under the Spanish Institute of Oceanography (IEO), included 55 specimens of bluefin tuna (Thunnus thynnus) in its breeding stock, which will increase the production of viable eggs.
Researchers also hope that these new tuna specimens will help increase the genetic diversity of the stock.
The 55 bluefin tuna specimens come from a surplus production of the company Caladeros del Mediterráneo, which was granted by written authorisation of the Secretary General of Fisheries, under the Ministry of Environment, Rural and Marine Affairs (MARM).
This initiative will also serve to validate and improve the excellent results obtained so far, mainly in the last season, when the egg laying obtained resulted in over 3,000 juvenile tuna specimens.
Many of these juvenile specimens are alive today and have already exceeded two kilograms in weight.
This initiative has been joined by IEO and by the Polytechnic University of Cartagena, with the collaboration of the Ministry of Agriculture of the Autonomous Region of Murcia.
The project is funded by Fuentes group and it is expected the knowledge of bluefin tuna larval rearing can keep widening.
Since June 2009, the bluefin tuna stock has performed mass egg-laying events of fertile eggs, according to IEO.
IEO scientists are confident they can complete the life cycle of tuna in captivity in the next four or five years, as part of SELFDOTT (Self-sustained Aquaculture and Domestication of Bluefin Tuna) project.
IEO and this company have worked together for over 10 years in various research projects.
"The industrial production of bluefin tuna by means of integral aquaculture techniques with the sustainable exploitation of fisheries, will contribute significantly to the reduction of the existing pressure on all the natural stocks of this species, thereby accelerating its recovery process," concludes IEO in a press release.
