| Title | The Biochemistry of Sabella spallanzanii (Annelida: Polychaeta): a potential resource for the fish feed industry |
| Abstract | To prevent over-exploitation of global fish stocks by the aquaculture industry, interest is growing
in 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 elemental
composition, gross protein and proximate composition, amino acid composition, total lipid and
fatty acid content, glycosaminoglycan (GAG) content and the extent of polychlorinated biphenyl
contamination were determined over an annual cycle. Sabella spallanzanii showed particularly
high gross protein (54.8±5.8%) and gross energy (4.89±0.5 kcal/g) content. All samples had high
concentrations of Na, K, Ca, and Cl. Saturated fatty acids were higher than monounsaturated and
polyunsaturated ones. A low ?-6/?-3 ratio (1.7) was recorded. Our results suggest that S. spallanzanii
can be used as a dietary supplement for farmed fish. The high concentrations of certain amino acids
that improve potential palatability for many farmed fish species suggest that S. spallanzanii extracts
can be used in artificial fish diets as an attractant. A further original aspect highlighted by this study
is the high concentration of GAGs, which are useful in pet nutrition and also in the nourishment of
farmed fish with a partially cartilaginous skeleton. |
