Changes in the glycogen content of freshwater bivalve Indonaia caeruleus (Prashad, 1918) with injections of cerebral ganglionic extract and equivalent commercial hormones (progesterone and estradiol) during winter season.

Abstract

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, as we know the importance of
neuroendocrine control on the metabolic physiology of freshwater bivalves. During winter season, the adult bivalve mollusc, Indonaiacaeruleus (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
