Considering the metabolic shifts in freshwater bivalve molluscs, during changes in the environmental parameters, we report here the effect of ganglionic extract and commercial hormones injections induced changes in glycogen content from mantle, hepatopancreas, gonad and foot of freshwater bivalve mollusc, Indonaia caeruleus (Prashad, 1918) from Godavari river. During monsoon season, the adult bivalve mollusc, Indonaia caeruleus (50-55 mm shell length) were subjected to the five respective experimental groups are as follows- 1) injection of commercial hormone progesterone 2) injection of ganglionic extract 3) injection of sham operation 4) injection of estradiol and 5) control (normal) for 10 days. The glycogen estimation in bivalves from all four groups (including control) was measured on 3rd, 6th, and 9th day. The study revealed that, the glycogen content was significantly increased from foot in progesterone injected group and decreased significantly from mantle as well as hepatopancreas in estradiol injected group on 3rd day. The content of glycogen showed significant decrease from gonad and foot in all experimental groups compared to control on 6th day. Whereas on 9th day the glycogen content increased significantly from mantle, hepatopancreas and foot in estradiol and ganglionic extract injected groups.
