Abstract

The proximate and fatty acid compositions of the flesh of cultured and wild common dentex (Dentex dentex), brown meagre (Sciaena umbra) and sharp-snout sea bream (Diplodus puntazzo) were evaluated. In all batches, cultured fish had higher values of fat contents. The lipids of cultured sharp-snout sea bream contained significantly (p<0.05) higher proportions of 18:1n-9cis, 20:1n-9, 22:1n-9, 18:2n-6cis and 22:2cis than the wild form. In addition, cultured common dentex contained significantly (p<0.05) higher proportions of 14:0, 20:1n-9, 18:2n-6cis, 20:5n-3cis and 22:6n-3. For these two species, the total polyenoic fatty acids content and the n-3/n-6 ratio were higher in the cultured than in the wild forms. Cultured brown meagre contained significantly (p<0.05) higher proportions of 14:0, 20:0, 16:1, 18:1n-9cis, 20:1n-9, 22:1n-9, 24:1n-9, 18:2n-6cis, 20:5n-3cis and 22:6n-3 than wild brown meagre. The total monoenoic and polyenoic fatty acid contents were higher in the cultured brown meagre, whereas the corresponding total saturated fatty acid content and the n-3/n-6 ratio were lower.
