Fattening of the Sea Bass in Cages


The production of juveniles in a controlled environment for the establishment of productive parameters started with a stock of sexually conditioned reproductive examples and a regular and spontaneous production of eggs. Important progress for the reproduction of this species has been achieved so far, which allows having a preliminary technology for the production of juveniles. 150 thousand post-larvae were produced for spring and summer 2006, which have been biological material for different growth and nutrition studies of this species. This is the first species cultivated in a confined system in open sea in the north of the country (Bahía de Tongoy), due to a project that was developed in conjunction with the private company.

The objectives of the project include developing the first experience for the fattening of juveniles from 40 g to commercial size in cages for the establishment of productive parameters.

A market research was developed to determine the economical potential of the Chilean sea bass (Cilus gilberti), which is refrigerated in a total of eight markets of U.S., the European Union, Brazil and Asia (in four continents and in eight target markets). We can conclude from the study that this species is about to become in resource of commercial farming. Some interesting results of that investigation are:

  • The Cilus gilberti is appreciated in all markets where it is presented, and it is compared to other species of high-medium quality, such as the European sea bass, the seriola or the acoupa.
  • Chile has good prospects to develop the commercial aquaculture of the Cilus gilberti, at least from a commercial point of view.

The management of the species is finished in all its phases from the technological point of view. There are just some complementary aspects for evaluation, such as better diets, genetic selection, better farming areas, etc.
