A group of researchers from the Centre for Technological Sciences of the Earth and Sea of the University of Valle de Itajaí (CTTMar/Univali), are evaluating the possibility of cultivating common snook (Centropomus undecimalis) in marine net tanks installed in Enseada da Armação do Itapocoroy, in the city of Penha, on the northern coast of Santa Catarina.
The aim of the initiative is to develop the methodology of cultivation this species during the pre-fattening stage, with the intention of diversifying aquaculture parks which were recently demarcated for shellfish producers.
This pioneering project is funded by the Foundation for the Support of Scientific and Technological Research of the State of Santa Catarina (Fapesc).
The study was conducted in association with the Company for Agricultural Research and Rural Extension of Santa Catarina (Epagri), the Federal University of Santa Catarina (UFSC), the Municipal Prefecture of Penha, the Maricultures Association of Penha and the company Nicoluzzi.
"The initial study will last two years and will serve to increase the amount of information relating to production technology, that will allow for a wider choice of options for the production of shellfish with marine fish production of a high commercial value," said Gilberto Manzoni, a researcher at CTTMar/Univali and one of those responsible for the project.
There are currently four tanks which have been installed, but only one contains fish. It is expected that in the coming months all the tanks will be in operation, informed Univali.
Common snook is a highly prized fish but increasingly rare due to overexploitation.
Proponents of the initiative also intend to eventually produce a specific feed for this species.
