Özet
Aquaculture of dentex commenced very recently compared to the culture of the traditional Mediterranean species such as gilthead sea bream and sea bass, which has increased in a spectacular way in recent years. Market supply in Mediterranean fish may be increased and a contribution be made to the development of aquaculture in diversifying the species being cultured, e.g. by culturing dentex. Yet, relatively few studies are available on this fish. In the current study, the proximate and fatty acid composition of the flesh of cultured and wild common dentex (Dentex dentex) were evaluated monthly during a period of 9 months. In parallel, color measurements and sensory analyses were carried out. Statistical analyses were done in order to compare wild and cultured dentex. According to the color values dentex which were cultured had a lighter and more yellow color than dentex caught in the wild. No significant differences between cultured and wild dentex were determined in the moisture content (p > 0.05). Yet, in the fat and protein content significant differences occured (p < 0.05) between cultured and wild dentex over the period of 9 months. The condition index values of cultured dentex were also in general higher than those of wild dentex. The analysis of the fatty acid composition showed that the EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) rates in the flesh of cultured common dentex were in general higher than those in the wild forms. In the sensory analysis wild dentex were perceived as having less fresh odor and fresh flavor and being less fat and less juicy. From the results obtained in the present work it can be concluded that cultured dentex can be an alternative to traditionally cultured species.
