Abstract

The marine fish culture is still quite incipient in our country, in spite of the intensification of the researches in that area in the last decade. The dusky grouper (Epinephelus marginatus) is a marine fish with great commercial acceptance, and its production technology in captivity has been developed, in Brazil, for Instituto de Pesca, since 2005. It was already possible to obtain the production in fingerlings in captivity, however, little knowledge is available on the growing of the species. Works on feeding strategies for rearing of dusky grouper are rare, turning the success of the fattening very random. Considering that the feeding corresponds the more than 50% of marine fishes production costs, the development of studies in this area is essential for the viability of the productive sector. Parallel, the development of systems of recirculation of salt water for production of marine fish presents countless advantages (almost zero exchange, larger control sanitarium, maintenance of the parameters environmental ideals for the species and possibility of being implanted moved away of the coastal area, turning possible the production of marine fish in interior of Brazil). This project has the objective of testing different feeding strategies for the fattening of the dusky grouper in recirculation aquatic system. As result is waited for an increment in the techniques of alimentary handling and the consolidation of the technological package for the commercial production of this species. (AU)
