A comparison of macronutrient levels in green mussel (Perna viridis) and brown mussel (Modiolus metcalfei Hanley)

Abstract

Two species of mussel from Panay Island, Philippines, have been analyzed for moisture, crude protein, crude fat, ash, carbohydrated, crude fibre and minerals (calcium and phosphrus). Results showed that the brown mussel (Modiolus metcalfei), both the marketable size and the small ones, have higher protein content (71.49 and 67.10% dry weight) than the marketable-size green mussel (Perna viridis ), 63.94%. The green mussel contained more fat but less ash, crude fibre and minerals than the brown mussel.
