Seasonal Changes in Glycogen Contents in Various Tissues of the Edible Bivalves, Pen Shell Atrina lischkeana, Ark Shell Scapharca kagoshimensis, and Manila Clam Ruditapes philippinarum in West Japan

Figure 2

Seasonal changes in glycogen content in different tissues collected from the pen shell, Atrina lischkeana. Bars represent means and whiskers represent standard deviation. 3–6 samples (replicates) were used for the analysis of each organ. No common letters out of parentheses indicate significant differences of glycogen contents in different tissues on each month and no common letters in parentheses indicate significant differences of seasonal changes on each tissue (; Tukey-Kramer test).
