Scientists of the Fish Farming Laboratory of the School of Marine Sciences of the Catholic University of the North (UCN) obtained the first spawning of its set of yellowtail kingfish (Seriola lalandi) reproducers.
This resource, which has great value in and out of Chile, was selected as one of the species for the future development in the north of the country.
According to Alfonso Silva, an investigator in charge of the study, this initiative allows Chile to "be able to initiate investigations related to the optimization of this species farming at different stages as well as to produce juveniles for farming," reported Aqua.
"It takes approximately 22 months to prepare the reproducer set at the laboratory facilities, and it consists of 25 specimens (40 per cent females) being between 9 and 12 kilograms in weight," added the scientist of UCN.
The team plans to perform the first experiences of yellowtail kingfish juvenile production over the next 60 days.
It is expected that this plan allows "the experimental protocol for juvenile production of the existing species in the laboratory to be validated and thus comply fully with the commitments obtained in the project Fondef DO7I1015, which is in its termination process," explained Silva.
Internationally, yellowtail kingfish is also known as palometa, vidriola and dorado.
At present, this resource is an attractive alternative of aquaculture farming in the north of the country, especially in the regions of Antofagasta and Atacama.
Meanwhile, the company Sociedad Inversiones Acuícola y Acuícola del Norte (Acuinor) is working on the development of the first yellowtail kingfish juvenile exports to the US and to some European countries.
