Marine species from the Egadi Islands 179

Finally, the saturated/polyunsaturated ratio was found to be very low for all the target
species, except Sepia officinalis, also compared to the aforementioned aforementioned
products, including mackerel.
It is important to highlight how all the species analysed showed TI values lower than AI
values, whereas meat from terrestrial animals has TI indexes higher than AI indexes [3].
This indicates that fish can be considered as a food suitable for the prevention of thrombotic
diseases.
In conclusion, this study can provide useful information on the chemical composition of
several important species from the Egadi Islands, highlighting good nutritional values. As for
marine species, the geographical location of catch, the season of the year, and the feeding
habits of the species are uncontrollable variables in terms of their chemical composition, and
further studies are in progress in order to fully characterize these species considering the
seasonal variation.
