Description 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.
