| Title | Effect of formulated diets on the proximate composition and fatty acid profiles of sea urchin Paracentrotus lividus gonad |
| Abstract | Three formulated diets were tested to evaluate their effects on gonad quality in Paracentrotus lividus. Experiments were conducted in parallel by the Consiglio Nazionale delle Ricerche (CNR) of Taranto (trial 1) and the University of Genoa (trial 2), in land-based systems. In both trials, somatic and gonadsomatic index (GSI) were measured and the nutritional profile of the sea urchins has determined significant variations in the biochemical composition. Sea urchins fed the experimental diets contained higher levels of nutrients (protein and lipid and carbohydrate) compared to wild sea urchins. However, total polyunsaturated fatty acids (PUFAs), especially EPA and DHA, and the n-3/n-6 ratio were lower in urchins fed with formulated diets. In both trials, sea urchins fed with diet 2 (SABS) showed a similar profile with PUFAs higher than SAFAs and MUFAs, the highest UNS/SAT ratio, although the highest n3/n6 ratio was observed in the group fed diet 3 (CNR). Atherogenicity, thrombogenicity, and hypocholesterolemic/hypercholesterolemic indices showed the best values in sea urchins fed diet 2 in both trials. |
