Total lipid, protein and glycogen content of the food and experimental mussels fed different diets.

Gross estimates for different microalgae diets (I. galbana; T.chuii; mixture of I. galbana and T. chuii; and commercial food) are based on the reports by Albentosa et al. (1996), FAO (2004) and Acuinuga Product Sheet. Values for M. galloprovincialis are based on the mussels fed ad libitum for 1 week on the respective diets. Letters in superscripts indicate significant differences between groups of dietary food type according to the Z-score test (p<0.05).
