| Abstract: | Oxygen
consumption rate (OCR) of the estuarine clam, Soletellina diphos (Linnaeus) was
studied in the laboratory. The OCR was measured against a range of body size
and weight, and under conditions of starvation, aerial exposure, temperature
and low salinity. The pattern of diurnal rhythm was also investigated. The OCR
was found to be inversely related to body size and body weight. It decreased
considerably with starvation but, with exposure to atmospheric air,
it increased up to 3rd hour and reached to the normal level by the 5th hour.
The OCR increased with rise in temperature from 20 oC to 35 oC.
It altered with decrease in salinity as compared to normal salinity (38 ‰), it
was highest at 70 % and lowest at 40 % of normal seawater. A distinct diurnal
rhythm in OCR was observed in these clams. The OCR was greater around afternoon
and at a lowest level around midnight. |
