Technological Innovations for the Yellowtail production

1/0

Fundación Chile carried out the first capture of yellowtail (Seriola lalandi) during the summer season 2003/2004 in the Guanaqueros Bay, Coquimbo Region. These yellowtails were transferred and placed on an earth pond with an open flow of seawater in its facilities in Tongoy.

In 2010, FCh won a FONDEF project, called “Aquaculture Diversification: Technological Innovations for the Yellowtail production (Seriola lalandi) in the Macro North Zone”.

There are currently 14 specimens weighing between 10 and 18 kg, which have laid spontaneously the first eggs in the pond. This fact has provided the biological material for the production of larvae and juveniles. In this sense, the spawning and the obtaining of larvae and juveniles have enabled Fundación Chile to obtain the first generations of yellowtail in captivity and, thus, to carry out the first registers of basic farming parameters.

The fishes are in earth ponds with supply of seawater, a diet based on fresh fish and nutritional enrichment and a daily register of the main environmental parameters.

The new challenges with this species are in the study of the reproductive physiology, the development of strategies for the larval, postlarval and juvenile farming, the nutrition during the ontological development of the species, and the production of fish health certificates to begin the experimental fattening activities in open systems (different bays of the macro north zone of the country).

This fish shows a great potential for the farming species. However, there is a fundamental aspect for its industrial development that still needs to be solved: the fattening. The management of the species has finished in all its phases, but its behavior during the last phase of the process is still unknown. It could be in cages or in earth ponds. This technology was achieved in earth ponds in other countries. However, it is not available to be acquired, that is why the own development will be selected.
