Resumen
La acuicultura en Chile liderada ampliamente por la industria del salmón, evidencia una clara necesidad de diversificarse con el propósito de disminuir su vulnerabilidad y consolidarse internacionalmente. El lenguado chileno (Paralichthys adspersus) ha sido considerado como una de las especies endémicas de mayor potencial. El cultivo en el mar de lenguado, presenta ventajas considerables respecto al cultivo en tierra, tales como un menor costo de construcción e inexistencia de costos energéticos producto del bombeo de agua de mar a los estanques. Esto impulsó el desarrollo de un cultivo experimental de lenguado chileno en jaulas sumergibles, en la bahía de Tongoy. Durante el experimento se modificó constantemente el sistema de acuerdo a las necesidades que fueron presentando los peces. El cultivo concluyó luego que un frente de mal tiempo causara mortalidades excesivamente altas. Los principales problemas surgidos fueron la incapacidad de la jaula de resistir el mal tiempo y la inestabilidad de su piso. Durante los cuatro meses de cultivo, se obtuvo un crecimiento mensual de un 13,2 % y un índice de conversión alimenticia de 2,1; por lo tanto, el cultivo sería factible corrigiendo los problemas detectados a lo largo de la experiencia.
Chilean aquaculture, primarily focused on the Salmon industry is showing a clear need of diversification in order to reduce its vulnerability and attain its consolidation in the international market. The Chilean Sole (Paralichthys adspersus) has been regarded as one of the species with high potential for that purpose. Using marine based sites to farm the Sole shows substantial advantages over farming on land, due to lower infrastructure costs and the saving of energy costs associated with sea water pumping. The latter compelled the development of an experimental project for farming Chilean Sole in submersible cages in Tongoy Bay. Modifications to the system were made constantly in accordance to the variable requirements of the fish. The farming concluded after a bad weather front caused and excessively high mortality. The main problems that emerged were the inability of the cage to endure bad weather and the instability and consequential deformation of the nets at the base. During the four months of farming a monthly growth rate of 13.2 % and a 2.1 FCR were achieved. Therefore, more efficient farming can be accomplished if the aforementioned problems are addressed and solred.
