This paper summarises some results from different research programs, from last decade, on the seed quality of Mediterranean aquaculture finfish. Since modern Mediterranean aquaculture began, the Laboratory of Experimental Ecology and Aquaculture, Tor Vergata University, has collected data on sea bass and sea bream. Inspections considered meristic counts and skeletal anomalies. Data analysis anomalies observed in sea bass and sea bream, both in wild and reared populations, allows to draw the following conclusions: (i) it is possible to assess the larval and post-larval quality of sea bass and sea bream by comparing wild and reared phenotypes; and (ii) different rearing techniques may modulate quality from a morphological viewpoint. Part of this information is currently being applied to new candidates for aquaculture (common sea bream, pandora, dentex, thick lipped mullet and sharpsnout sea bream) and could be further applied to other finfishes to evaluate the development stage of a diversified and responsible Mediterranean aquaculture.
