Resumo: | The cuttlefish Sepia officinalis, is one of the main species capted in the Basse-Normandie fisheries. These animals are principally exportated in eviscerated and frozen form to mediteranean countries and to Japan. Then, high quantities of co-products are available from factories transformation of cephalopods. Enzymological and biochemical studies on co-products demonstrated an elevated potential in the valorisation of viscera by silage technical. Two silages are developed in our laboratory: LBBMA4 and LBBMA25. Primarly, they are studed in vitro as substrate for the culture of micro-organisms. This study established that silage LBBMA25 permits to obtain good growth cinetic and biomass, with comparable results to commercial peptone. Secondary, silages can be used as dietary complement. In this way, using silage LBBMA4 or LBBMA25 at low level in diet of post-larvae crustacean or juvenile mollusca and fish allowed to increase zootechnical parameters and to stimulate ontogenesis. Research on bioactive molecules in silage shows the presence of growth factors-like, digestion regulator and immunostimulator molecules. All data obtained during this study, demonstrated that our cuttlefish silage from co-products possess numerous applications.
