Table 3.
Mineral composition (mg/Kg WM) of Ostrea edulis in different seasons. The results are expressed as means (n = 3) ± SDs. Results from ANOVA show significant differences between the means. In each row, the means that are not statistically different are indicated with the same letter (A, B, C) as a superscript (Tukey’s test, p < 0.05).
