Abstract

To prevent over-exploitation of global fish stocks by the aquaculture industry, interest is growingin the identification of nontraditional species with potential value as fish feed. In this study,we investigated the biochemical composition of the polychaete Sabella spallanzanii . Its elementalcomposition, gross protein and proximate composition, amino acid composition, total lipid andfatty acid content, glycosaminoglycan (GAG) content and the extent of polychlorinated biphenylcontamination were determined over an annual cycle. Sabella spallanzanii showed particularlyhigh gross protein (54.8±5.8%) and gross energy (4.89±0.5 kcal/g) content. All samples had highconcentrations of Na, K, Ca, and Cl. Saturated fatty acids were higher than monounsaturated andpolyunsaturated ones. A low ?-6/?-3 ratio (1.7) was recorded. Our results suggest that S. spallanzaniican be used as a dietary supplement for farmed fish. The high concentrations of certain amino acidsthat improve potential palatability for many farmed fish species suggest that S. spallanzanii extractscan be used in artificial fish diets as an attractant. A further original aspect highlighted by this studyis the high concentration of GAGs, which are useful in pet nutrition and also in the nourishment offarmed fish with a partially cartilaginous skeleton.
