The role of equivalent commercial hormones and cerebral ganglionic extract injections in regulation of oxygen consumption of fresh water bivalve mollusc, Indonaia caeruleus (Prasha, 1918) during monsoon season

Thorat SK and Vedpathak AN

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 respiratory metabolism 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 a) control (normal) (b) injection of a cerebral ganglionic extract of same species to intact individuals (c) injection of equivalent commercial hormone progesterone to normal control and (d) injection of estradiol to normal control for 8 days. The rates of oxygen consumption in bivalves from all four groups (including control) were measured on 2nd, 5th, and 8th day. The study revealed that, the rate of oxygen consumption was significantly decreased in cerebral ganglionic extract injected group on the 2nd day. The rate of oxygen consumption also showed significant increase in estradiol injected group and ganglionic extract injected group on 5th day. The rate of oxygen consumption showed significant decrease on 8th day in progesterone injected as well as an insignificant decrease in ganglionic extract and estradiol injected groups.
