A team of researchers from the Spanish Institute of Oceanography (IEO) obtained viable eggs from the Atlantic bonito (Sarda sarda) in the third generation in the Marine Culture Facilities in Mazarrón, from the Murcia Oceanographic Centre.
Since last May 5, scientists have been collecting tens of thousands of Atlantic bonito eggs on a daily basis, which are being used to carry out the larval rearing and to advance the process of domestication of this species.
Last year, the researchers behind the project, Aurelio Ortega and Fernando de la Gándara, managed to close the life cycle of this species in captivity.
These research activities are developed under the SELFDOTT (Self-sustained Aquaculture and Domestication of Bluefin Tuna) project, coordinated by IEO and co-financed by the 7th Framework Programme of the European Union.
Even though the main objective of this project is to reproduce bluefin tuna (Thunnus thynnus) in captivity using aquaculture techniques, the Atlantic bonito is considered as a model species because both resources come from the same family.
Apart from its commercial value, Atlantic bonito is unique in that both males and females mature the first year of life, while most of the cultivated species do in three or four years.
Experts from Murcia Oceanographic Centre began to explore the Atlantic bonito in 2006, indicated the press release of the IEO.
