This paper is a review of the diverse results on marine finfish aquaculture diversification obtained at the 'Estación de Acuicultura' (Port of Andratx, Majorca) from its beginnings to nowadays. We expose the results obtained with the main finfish Mediterranean species investigated, briefly describing the capture of the individuals from the natural environment, the breeding, rearing and ongrowing technics, as well as the main pathological problems observed in our aquaculture facilities. We resume our results obtained with three finfish species: the amberjack, Seriola dumerili (Risso, 1810), the common dentex, Dentex dentex (Linnaeus, 1758) and the sharpsnout sea bream, Diplodus puntazzo (Cetti, 1777).
