Dharmaraj, S (1982) Oxygen consumption in pearl oyster Pinctada fucata (Gould) and Pinctada sugillata (Reeve). In: Proceedings of the Symposium on Coastal Aquaculture, Part 2, MBAI, 12-18 January 1980, Cochin.
The rate of oxygen consumption of pearl oysters Pinctada fucata and P. sugillata from different localities namely pearl culture farm, pearl banks and near-shore waters of Tuticorin in the Gulf of Mannar has been studied. In P. fucata oxygen consumption was 1339 /l/hr. for oyster size range 40-50 mm; 1650 μl/hr for 50-60 mm and 1810 |il/hr for 60-70 mm. The rate of oxygen consumption of P. sugillata from the pearl banks as well as from the near-shore waters showed a linear relation with size of oyster. The rate of oxygen consumption of i>. sugillata from pearl banks (depth 12-21 m) was less when compared to that in the oysters of the near-shore waters (depth 0.5-1.S m). P. fucata from pearl culture farm survived after 21 hours of exposure to air. P. fucata from pearl culture farm could survive upto 19 hours, upto 24 hours in the case of P. sugillata from near-shore waters and upto 27 hours in P. sugillata from pearl banks, in anaerobic conditions. In all the oysters there was remarkable increase in shell activity and shell gape when there was a decline in the oxygen level.
