Considering the importance of neuroendocrine control on the metabolic activities of freshwater bivalves, we report here the effect of injections of cerebral ganglionic extract and equivalent commercial hormones (Progesterone & Estradiol) on glycogen metabolism of freshwater bivalve mollusc Indonaia caeruleus (Prashad, 1918) from Godavari River. During summer 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 lipid estimation in bivalves from all four groups (including control) was measured on 3rd, 6th, and 9th day. The study revealed that, the lipid content was significantly increased from hepatopancreas, gonad and foot in ganglionic extract injected and estradiol injected groups on 3rd day. Whereas the lipid content decreased significantly from all the tissues in all experimental groups compared to control on 6th day. The content of lipid on 9th day increased significantly from mantle as well as gonad in progesterone injected group and it was significantly increased from hepatopancreas in estradiol injected group.
